Moodmetric smart ring – Finnish know-how at its best

The Moodmetric smart ring is a prime example of Finnish innovation in the area of health technology. Vigofere Oy was set up as a company five years ago to commercialize the invention of Henry Rimminen, D.Sc., who had developed a smart ring which measures electrodermal activity (EDA). The ability to measure, outside of test laboratory conditions, the electricity that your body emits was revolutionary and 2013 saw the birth of the first prototype for further development.

How It All Begun

As a researcher at Aalto University, Henry Rimminen had worked on various sensors and methods for measuring physiological activity. Fitness trackers were a growing trend and devices based on measuring heart rate had been available for consumers for some time already.

Measuring electrodermal activity had been in research use for over a hundred years, but there were no practical applications of the measurement method on the market for consumers. It was this challenge that Henry Rimminen aimed to solve.

Our bodies react to external stimuli, both psychological and physical. This triggers off the sympathetic nervous system, the activity of which can be measured by how the eccrine (very tiny) sweat glands respond. These glands are dense on the palm of our hands, making them the optimum location to place the measuring sensor on.

EDA, or skin conductance, is a phenomenon which was discovered by two researchers, Charles Vigoroux and Richard Féré in the late 19th century. The name of the company, Vigofere Oy, was derived from the names of these two trailblazers.

The Challenges

In laboratory conditions EDA is measured by placing electrodes on the skin, usually on the tip of two fingers. For an accurate reading, no movement is allowed.

To develop a consumer product, Henry Rimminen had to overcome several challenges:
• Downsizing the measuring device from the size of a block of cheese to as small as possible.
• Instead of restricting the use of two fingers, the device had to be effortless to wear in everyday life.
• The results should not be affected by physical movement.
• Data transfer should be wireless.

Early prototypes of the Moodmetric smart ring
Early prototypes

In the autumn of 2015 the first commercial version of the Moodmetric smart ring was launched. It was the result of many iterative rounds of research and development. Once the electronics and measuring capability were deemed robust enough, designer Vesa Nilsson provided the ring its Scandinavian look and feel. Vesa Nilsson is famous for transformational and clean design. For further information, see Oz Jewel.

Data Management

One of the key principles Henry Rimminen followed right from the start was ease of use: It was imperative that the data the ring collects could be effortlessly retrieved, read and managed. Developing an application running on a smart phone was the next logical step.

The mobile application had to incorporate two basic elements:
• The index with the numeric values 1-100 is calculated from the raw data and show the alertness level of the person wearing the ring. High numeric figures signify stress or excitement, low figures a sense of calm.
• A round diagram demonstrates the fluctuation of the stress levels during 12-hour intervals. The use of colour make it easy to visualize, in one glance, the different levels of alertness, sliding from red for high levels on the outer peripheral of the diagram to the light greens of low stress levels on the inner circle of the diagram. For further information on the Moodmetric index and data interpretation, see here.

A high school wellbeing project aimed at better self awareness with a physiological stress measurement

In Lempäälä high school, Finland, a large wellbeing project has been initiated. It aims to give the students practical tools to manage both their physical and mental wellbeing better. The pilot group in the fall 2018 had the possibility for a 2 week Moodmetric measurement. Surprisingly high stress levels were measured both with students and teachers.

Society and the working life expectations are transforming. The world we and our kids live in is changing every day and this all requires constant adaptation. According to Psychology Today, the average high school kid today has the same level of anxiety as the average psychiatric patient in the early 1950’s.

Practical approach to better wellbeing of students

The teachers in Lempäälä high school, Finland, have understood that things cannot be done as in the past.  Finnish core curriculum for basic education is on excellent level and under continuous scrutiny to match the future requirements for today´s youth.

But in Lempäälä they want to cover more than the basic agenda. They want to support the students to find their strengths and hidden talents early on. Better self awareness and understanding of what is best for myself are needed in the world of information flow and continuous stimulus. Own place within society and working life seems to be more and more difficult to plan and the feeling of insecurity can be stressful. A good self understanding helps to make right choices in life.

Jarmo Lehtinen is a teacher who wants to equip the students in the best possible way for the future working life – and life. – We learn by doing, we execute a lot of practical projects and try new things, we are not here just for theoretizing. The students are creative and innovative in a group they know and can trust. In it, it´s easy to get to know also difficult and hard topics.

Students get active for their own wellbeing

In the fall 2018 personal wellbeing has been in focus. – They say that we should be careful not to put too much pressure on the students. But the future will be very demanding, there will be a lot of things that need adaptation. We are learning stress management proactively, says Jarmo Lehtinen. – In media they discuss a lot of how young people are tired of school. I’d sat it’s not just school, but all the other things beside it, too. The whole life can be tiring these days. That’s why we need to aim for balance in everything, Lehtinen continues.

Lempäälä high school has taken a holistic approach to wellbeing. Everybody knows by now the 8+8+8 model. It means that there should be work, free time and rest in right proportions in the day. Sleep, exercise and stress management have been covered in a project led by an external coach, Pertti Ratilainen.

Before the project the teachers agreed that there should be tangible measured data. This would be important both in getting a good picture on wellbeing of the students but also in ensuring funding for the project. The Moodmetric smart ring measurement was chosen for a 2 week period for everyone participating in the pilot project. The measurements were done in October and the pilot was concluded in December.

What was learned from the Moodmetric measurement?

Students Karita Tanni and Kristian Haapalehto were glad to take part in the measurement. – I really looked forward to the measurement, I wanted more information of how my body works. When I got the ring, it was really interesting to follow the real time data, Karita Tanni.

The Moodmetric measurement data shows what stresses out and what calms down. For high school students it was surprising how strongly the mind could react and how it could stay active for a long time. On the other hand, a good focus on homework was well shown as low Moodmetric numbers. Relaxed states were also measured e.g. while driving or spending time with friends. These were the positive learnings that the students learned to look for. – With the Moodmetric measurement, I found ways how not to stress, says Kristian Haapalehto.

Also the teachers got interested in the measurement

The Moodmetric measurement was originally intended just for the students, but the teachers wanted to participate as well. We wanted to show the principal, how stressful our work is, laughs Jarmo Lehtinen.  – For students it was a surprise how many loading factors there were outside of school. For teachers the challenges of everyday life were more familiar. Jarmo Lehtinen gives an example: -We have a puppy now, which already makes a big impact for how much sleep I am getting – or not getting!

According to the Moodmetric measurement the school days have been quite active for both the students and the teachers. This can be a sign of enthusiasm, and of the joy of learning new things. High levels can also be a sign of negative stress. This would mean high Moodmetric levels combined with general negative experienced mood. In these cases it would be the most important to look for moments of recovery.

The sleep

Many were surprised to see how different the nights were from one to another. – One night was not similar to another. The most valuable insight personally was how much I can do myself to sleep better. What I do during the day and evening has a huge impact on sleep. Watching a soccer game where my team finally lost was not the best preparing for the night, grins Lehtinen.

Do I have the willpower to change my habits?

Young adults are very well aware of the factors affecting their wellbeing. Good habits have been discussed at home – the parents remind of the bedtime and try to limit the time spent on smartphone.

Knowing what is good for us is not enough. The difficult part is to change habits for better wellbeing, says Pertti Ratilainen. -This is difficult especially to adults! Even a small increase to sleep or outdoor activity seems to be very difficult to do.

The students of the Lempäälä high school show that they can do better. During the project, 80% of the participants had made positive changes for their own wellbeing.

This is just a beginning, says Jarmo Lehtinen. – We are planning a much larger project for next semester. We aim to include every 1. and 2. year student to be active for their own wellbeing. The effects of the products we expect to see in learning and school work immediately. In long term, it would be great to provide these students practical wellbeing tools for the entire life.

Good start to stress management

The starting level and objectives in stress management are as important as when maintaining physical condition. An employer wishes that every employee is with good health and well-being for the duration of their career. Most companies systematically take actions to promote this. When looking at stress management from an individual point of view, there are as many situations as people.

From a physical point of view someone might have as an objective to spend less time on a couch. Another wants to run a marathon or win a competition in weight lifting. Regarding the mental well-being, too many just would like to manage it until tomorrow.

“5 simple ways to live a less stressful life” or  “7 tips to managing daily stress”  are interesting titles and lead thoughts to how things are in ones´ life. Often these tips do not take into account the big picture nor is the experienced stress positive or negative.

The Moodmetric smart ring is the only wearable that shows the cognitive and emotional stress real time, and enables measuring also in long term.

The Moodmetric measurement data from several years has brought better understanding on stress

Analyzing the Moodmetric  data over the course of four years has helped us to better understand the fluctuating stress levels. The measurement periods are are from 2 weeks to years, which enables seeing how changes in life affect the stress levels. It has become clear, that a person’s starting point plays an important role in stress management.

1. People stress differently

Based on the Moodmetric measurement people can be roughly divided to two categories

  • Reaching high stress levels often and easily, both out of excitement and of negative stress. This means reacting often very strongly to emotional and cognitive stimuli.
  • Those who react more flatly, have less deviation from average values. Also these people can reach high Moodmetric-levels very fast, but they normally soon return back to equilibrium.

In the first group people might need to pay more attention to recovery every day. Sleep can be very deep when balance has been gained.

Example: A typical Moodmetric 24 hour measurement of a person easily reaching high stress levels. On the left the day from 6am to 6pm, on the right the night from 6pm to 6am.

In the second group the recovery during the night might not need to be as complete. This is because the load of the sympathetic nervous system is more modest during the day.

Example: A typical Moodmetric 24 hour measurement of a person with modest response to stress. On the left the day from 6am to 6pm, on the right the night from 6pm to 6am.

It is good to understand my own way to react to stress. There are as many ways as there are persons, and this can also change with different phases of life.

No way to react is better than the other. During evolution all types were needed – this has not changed. People acting differently are needed in social and occupational context. Diversity is good also regarding stress responses. 

2. You need to recover also from excitement

Also positive stress can wear out when going on for a long time. People devoted to their work, entrepreneurs, creative people and many others sometimes enjoy positive stress for too long. A dream job can also lead to burnout.a.

Devices and tests might tell a lot, but the most important is own experience. What is the situation in my life – the work, family, leisure, friends? Do I feel things are pretty good, or is some area of my life very demanding right now? If I say I am stressed, what does it feel like and how does it affect my life?

The Moodmetric smart ring is a support for individual stress management. It gives valuable measurement data and helps in better self understanding.

The measurement data always needs to be put in the context of own life. Same numbers can in different situations mean a different thing. Very low Moodmetric levels have been measured both with depressed and those who are simply always calm.

3. Good start to managing stress is to understand oneself and one’s life

What stresses me out, how do I calm down, what is my individual way to react? A short practice: Can you easily place yourself to the below fourfold table of wellbeing? No that your position might vary depending on whether you think of work, family or other part of life.

The wellbeing fourfold is for determining how high is the stress/arousal level, and is the state positive or negative. The Moodmetric measurement shows the stress level on a scale of 1 to 100. The app Analytics screen shows the chosen categories of life on a similar fourfold, when the user has defined the mood as pleasant/unpleasant. (Use the Diary feature for this.)

When defining where I am on the map, it is good to understand what was discussed in point 1: how do I react to stress. Some people mainly move in lower part of the picture, high levels of stress or excitement are not natural. Whether stress level is low or high, the right side of the fourfold is better in long term.

the Moodmetric measurement helps to manage stress better

The Moodmetric measurement helps to put oneself to the correct spot on the picture of own life and stress. What stresses me out, what not, what are my stress levels comparing the objective – ie. balance?

– What Moodmetric levels one should aim at?

No single measurement result is good or bad. In long term the objective is balance. This means that sleep and rest during the day compensate the activation of the sympathetic nervous system due to emotional or cognitive load. When the Moodmetric daily average number is about 50, it indicates balance of the autonomic nervous system.

Good start to managing stress is to acknowledge own situation as accurately as possible. Measured cognitive and emotional load is often both a support and a motivating factor.

Do you study stress, customer experience, attention or decision making?

The Moodmetric measurement gives accurate and real time data on cognitive and emotional load of an individual. Use cases below give a snapshot on what kind of research it can be applied to. These are just a handful of examples. Electrodermal activity is a signal with great and for most unused potential in field research.

Stress measurement with Moodmetric

Positive stress is a good thing and when in control, it takes us forward. Chronic stress reduces productivity, creativity and job satisfaction and it is a risk for physical and psychological health. It is not easy to catch signals early and stress might not be detected before it has reached harmful levels.

Questionnaires are subjective and bound to a certain moment. Preventive stress management needs continuous and long term measurement. The Moodmetric ring is intended for weeks and months of use. The mobile app offers a real time view which enables insights that can be actioned immediately.

Even though the Moodmetric measurement is primarily intended for use at occupational health, the real time measurement enables several kinds of research. Below are some example use cases to give a picture of it´s possibilities:

Customer experience

A customer is testing a new shopping center virtually. The center is equipped with innovative implementations, including parking, navigating inside the center, paying in the shops (only mobile payment) etc. The pilot customers´ opinion have a major significance on the final drawings and the pilot is heavily studied. The Moodmetric measurement shows instantly and in real time the pain points – when the experience is getting from smooth to troublesome. The Moodmetric levels increase in seconds when the customer is perplexed.

A much simpler example would be e.g. driving through a car washing lane. How many of the customers actually get terrified inside, with not way of getting out in the middle? Could this be eased out somehow?

The Moodmetric measurement can be used to tracking stress levels in any environment, inside or out in the woods. It suits to observing a person in different situations, like choosing clothes. Which print makes the person react?

Gaming

Mobile and desktop games can be extremely agitating. Chasing, fighting, racing and performing dangerous tasks is enervating. The sympathetic nervous system of the player is active, as the body does not understand that the threat is just an illusion created by the game developer.

A game can also be soothing, like puzzles. Focus is needed but vigilance not.

What kind of a game is yours and what is the target audience? What if you could design games that really calm down the sympathetic nervous system – a game that you could wholeheartedly recommend e.g. for kids with concentration difficulties?

Pay attention! – Study focus with Moodmetric

We make better decisions, our movements are correct and precise, and we make better analysis when we pay attention. Really pay attention by not letting noises, lights, phone, emails or the smell of lunch distract us.

The Moodmetric index of 1 to 100 tells our arousal level. When focused, the level is below 30, in most cases below 20. Full focus on the task at hand might show a steady level of 12 with almost a straight electrodermal activity curve on the Moodmetric mobile app. The person is far from being sleepy (although in the evening at the sofa the numbers might be exactly the same), but fully focused.

This does not necessarily need an isolated environment. Most people can find their way to reach focus no matter the surroundings. But as it is not easy, many companies design spaces and areas inside their offices that enhance concentration.

Sports

What kind of training methods provide the best results? The Moodmetric measurement makes it possible to better understand what level of focus the athlete reaches. Interventions such as mental exercises can tested and found out the ones with the best results for improving concentration. The measurement also provides insights as to when recovery from practice is sufficient. The app diary helps to analyse which activities should be toned down or avoided in order to benefit optimally from training.

PART 4: The Moodmetric ring stress measurement and understanding the data

This article series tell about stress and ways to measure it. Parts 1 and 2 describe the fight or flight reaction and how the body reacts to chronic stress. Methods for long term monitoring are presented in part 3. In this article we explain the Moodmetric ring measurement and how to interpret the data.

The Moodmetric smart ring measures electrodermal activity. It detects skin conductance with the band of the ring that works as electrodes. The band consists of two silver coated steel rings, and an insulator band in between them. 

Electrodes need to get a good contact with an area on skin where the eccrine sweat gland density is high. This varies from 400/cm2 on the palm to about 80/cm2 on the upper arm. A ring form for the Moodmetric sensor has been chosen to reach the best possible accuracy. The measurement point is on the palm side of the finger and at best the signal is unbroken.

The ring measures continuously and stores the data inside the ‘stone’. The mobile app does not need to be on, nor the phone near the ring. When the app is opened and the calendar icon chosen, the ring sends the data to the app via bluetooth connection. The measurement and data storing to the ring continue immediately. The real-time signal can be followed any time with the app.

Research by the Finnish Institute of Occupational health (2015) shows that the signal of the Moodmetric ring is comparable to that of a laboratory device. The ring is applicable for field studies.

The Moodmetric signal is real time

The Moodmetric signal is the violet curve on the mobile app that can be observed real-time. It is the raw measurement signal but auto scaled in order to have the whole amplitude visible even during strong reactions.

The curve enables analysis of single reactions. Even a thought can cause a peak: excitement, idea, awe – each reaction forms a peak within a 1-2 second physiological delay.

Interpreting the raw signal requires expertise in the measurement method and understanding the possible sources of error.

The Moodmetric index is easy to interpret

The electrodermal activity (EDA) raw signal is difficult to interpret and prone to errors. Strong reactions can easily be spotted on the curve,  but mathematical methods are needed for further analysis.

The Moodmetric index or the Moodmetric level has been developed to provide accurate EDA measurement data that is easy to interpret. The algorithms count an index from 1 to 100 so that 1 is the lowest the person can reach. This is possible e.g. in deep sleep. 100 is the maximum arousal, strongest possible reaction of the person. Finding the min and max takes about 12 hours, which is the calibration period. The ring can be re-calibrated e.g. when changing from one user to another.

The Moodmetric index/level tells the activity level of the person at a certain moment, looking at a few minutes´ time window. The level does not indicate single reactions but changes fast if the arousal level of the person increases or decreases rapidly. E.g. increasing is first seen in growing amplitude and raising trend of the Moodmetric curve, then in higher Moodmetric level.

It is easy to get to 100. What is more interesting is to make rehearsals that aim to calm the mind, to get the index as low as possible.

In counting the Moodmetric index, the algorithms minimize the effect of finger’s movement and the skin normal moisture level on the measurement. The index is comparable between users. If two persons are at a same situation it is possible to observe which one is calmer.

There is no momentary optimal value

It is normal that the Moodmetric level fluctuates between 1 and 100 during the day. No momentary value is good or bad.

Important is also to know, that the Moodmetric measurement does not tell whether a reaction is positive or negative. The Moodmetric ring is not an emotion detector.

The fluctuation of stress levels is individual

There are people who react fast and strong, while others respond more calmly. For instance creative people are often very prone to stimulus and they get a lot of new ideas. This can be seen in high Moodmetric levels as well as big fluctuation. A person doing work that requires deep and long concentration might have low Moodmetric levels throughout the working day.

The levels can be high due to excitement and energy, or low due to good focus. All this is positive. The levels might also be high due to pressure and lack of control at work. Low figures in turn can tell of boredom or even depression. The measurement data always needs the ring wearer´s own perception of the situation. No one else can tell whether the 100 on the mobile app tells of excitement or irritation.

A good team is heterogeneous also by the way they react

At workplace it is good to have people with different ways to react. A team with individuals that all have a very mild or a very strong natural way to react, probably is not as productive as a more heterogeneous team.

The Moodmetric measurement helps to understand individuals and personal ways to react. This is important from wellbeing point of view. We should rather challenge ourselves keeping in mind our own physiology and environment, than compare to others.

The Moodmetric daily average level is the most important

The Moodmetric smart ring measures the sympathetic nervous system reactions on a scale from 1 to 100. Counting presumes balance. When the daily average value is around 50, there is enough recovery in correlation to load. The Moodmetric ring users notice the same: the daily average is normally 45 to 55 depending on how well daily load is compensated by rest and sleep.

Levels and fluctuation during the day can be very different between two persons. Both might still feel well and with plenty of energy. If high daily figures are combined with very restful sleep, can the daily average level be the same as with a person with much lower numbers during daytime. 

Below the different persons’ consecutive day and night views, where the daily average for both arrived at 46. In this example both reached good, quite a low average, but with very different daily levels:

The daily average of the Moodmetric index is the more informative, the more the person uses the ring. It is easier to analyse own balance of load and recovery when the ring is worn also during the night.

Feedback from the Moodmetric ring users tells that own perception is in line with the measurement. If the daily average is around 50, the situation and energy levels are normal. Values over 50 for a long time go hand in hand with the feeling of overload and weakened wellbeing. Very low daily figures might indicate depression.

The Moodmetric measurement helps the user to gain balance between load and recovery. The sources of stress and ways to recover are individual. For this reason the measurement data always needs own evaluation. Categorizing and analyzing own life e.g. with the help of the Moodmetric app Diary feature is a way to more balanced life.

PART 2: Chronic stress – The brain concludes that we are continuously in danger

The autonomic nervous system regulates the functions of our body as situations so require. Recovery and healing systems are the most active during sleep.  After lunch it is important to digest the food and use the nutrients efficiently. When faced with imminent threat, the immune system and food processing are not important. These functions are turned off to conserve all possible energy for the use of muscles, which are needed in the fight-or-flight response.

By and large, the autonomic nervous system works unconsciously. It is responsible for many vital functions such as blood pressure, temperature regulation, digestion, and function of the adrenal cortex.  It works through the neural network that controls the heart and other organs. The autonomic nervous system keeps us alive without us knowingly doing anything about it.

The autonomic nervous system consists of two complementary parts, the sympathetic and parasympathetic.  When active, the parasympathetic nervous system slows down our heartbeat, enhancing digestion and healing. It strives to calm the body down and keep the vital functions stable.

The sympathetic part is responsible for preparing our body for action, with the axons (nerve fibers) of the system being able to innervate tissues in almost every organ. The sympathetic nervous system becomes active in stressful situations and during hard physical strain.

Both parts of the autonomic nervous systems normally work in good cooperation, but as a seesaw.  When the other becomes active, the other slows down. For instance, in acute stress reaction the sympathetic nervous system works at full speed, in an instant. The parasympathetic part ceases to operate and, for example, digestion almost comes to a halt. The sympathetic and parasympathetic systems have evolved to enable accurate and fast regulation of our internal mechanisms, regardless of the situation.

The fight-or-flight response is a way for us to cope in a threatening, rapidly escalating situation. In the time of cavemen, situations requiring response were normally quickly over and fights did not last for weeks or months. For us today, things can be completely different: The stress reaction might be a permanent state, and the parasympathetic nervous system does not have the chance to return our body to rest.

In long term stress the cortisol levels in our body are continuously high

Chronic stress keeps the hypothalamic-pituitary-adrenal axis active. It is like an idling motor, pumping stress hormones, such as cortisol, to our system.

Cortisol helps us to confront the threat, but it simultaneously shuts down the immune system. From the evolutionary point of view, this makes sense: If a crocodile attacks, we can shut down all the functions in the body that are not essential for fleeing or fighting. The immune defense of our body is weakened when we are continuously stressed, and this might lead to a series of infections. Stress factors also play a role in the development of autoimmune diseases, heart and blood vessel diseases, and cancer. Continuous boosts of adrenaline can harm blood vessels, raise blood pressure and increase the risk of cardiovascular diseases.

Worrying and fear increase our mental load and can put further strain on the sympathetic nervous system; physical symptoms persist, recovery via beneficial rest and sleep does not happen.

Heavy cognitive and emotional load during recovery from an illness might be as bad for our body as physical exercise. Our body would choose to put the work aside when being ill.

Chronic Stress affects memory, concentration and appetite

In a state of chronic stress, the brain thinks that a physical fight is about to start at any time. Cortisol, in turn, tells our body to have much energy available. It then enhances appetite and storing of extra energy, with might lead to weight gain.

Cortisol is also released to the hippocampus, the part of our brain which is central for memorizing and learning. A stressed-out person has difficulties in learning and regulating their emotions. There are also often problems associated with concentration and memory.

Burnout

Chronic stress cannot go on forever without its repercussions. Burnout is the consequence of chronic stress causing severe disturbance to our vital physical and mental mechanisms. A simultaneous collapse of our psychological, neural, metabolic and immune systems might be so all-encompassing that a complete recovery is very slow or even impossible.

The best cure for burnout is prevention. It can be difficult to accept the graveness of the situation. People tend to compare themselves and their work rhythms to others, set the bar too high and pretend that everything is fine. Just moments before the disintegration takes place, everything might appear quite normal for the people around.

Talk to your friends and family, colleagues, your superior or a health care professional if you feel that the load is too high. Usually the first cautionary signs are linked to changes in your sleep patterns.

The brain, sleep and stress

When our lives are in balance, we recover from acute stress reactions and even longer burdensome periods of strain. We all experience major turning points in our lives: a newcomer to the family, moving house, a study or work project that is exceptionally demanding. We overcome these changes and challenges when the quality and amount of recovery is sufficient enough.

Sleep is our most important means of recovery and an indicator of balance. Weeks and months of disturbed sleep is a sign of stress, and sleep deprivation further weakens our resilience to adapt to the challenges we have to deal with.

The brain needs sleep. During sleep our bodies repair and restore in ways we’re not aware of. It is almost like we need a nightly reboot to feel physically and mentally well.

There is no health without sleep. The importance of proper recovery becomes clear after experiencing periods of sleeping poorly. At worst life is reduced to mere coping. Unfortunately, this is reality for so many of us, so much so that we have begun to think it is normal not to sleep enough. But this couldn’t be further from the truth.

When we sleep well most nights and feel refreshed in the morning, our body and mind are better prepared to perform well. We are in balance.

PART 5: The Moodmetric measurement in preventive occupational health

Stress is a good thing, it is our driving force keeping us active and productive. However, excessive amounts of stress can lead to  overload, especially when the stress load is out of our hands. Chronic stress is a state where stress outweighs recovery. The autonomic nervous system is off balance and the body is continuously in alarm mode.

Chronic stress is in connection with several physical and psychological illnesses, and it is often behind burnout. Overload is difficult to recognize because it builds up over a long period of time.  Stress can also still be a taboo, and people seek help too late. According to research, even 60-80% of medical visits are in connection with stress (Nerurkar et al. 2013). Every fourth tells to suffer from work related stress at some point of their working life.

The Moodmetric measurement of electrodermal activity

The Moodmetric smart ring is one of the first devices to measure long term stress by interpreting the phenomenon of electrodermal activity / skin conductivity. This physiological measurement can accurately tell about fluctuating stress levels in daily life. Electrodermal activity measurement is especially sensitive to detect changes in emotional and cognitive stress. This makes the Moodmetric smart ring a great stress management tool especially for knowledge workers.

The Moodmetric smart ring is easy to use, and the measurement results can be observed real time on a smart phone screen. A minimum suggested measurement period is two weeks, but the measurement can go on for years when needed. In two weeks the user learns the individual sources of stress and recovery, and gains motivation to seek better balance.

The Moodmetric measurement is real-time, informative, accurate and the ring is comfortable to use also in long term.  The mobile app content is visual and the real time view enables immediate actions. This is very important when seeking behavior changes. Findings can be applied to practice right away.

According to customer feedback, the data collected by the Moodmetric smart ring helps to better recognize individual sources of stress and recovery, and motivates to take concrete actions.

Moodmetric provides new services to Preventive occupational health

The Moodmetricin reseach and development has been strongly guided by our customer feedback. Customer comments and use cases have been collected since 2015. Especially our corporate customers have repeatedly expressed their wish to have the Moodmetric services available at the occupational health. Individuals often look forward to receive professional help to measurement data interpretation, as well as to better understand good stress management practices.

The occupational health has a limited selection of tools to offer the customers that seek help to manage stress overload, or whose health issues are clearly stress related. Most occupational health customers might not need continuous stress measurement in long term, but they wish a measurement to be available as a service when needed and for as long as needed.

Wellbeing technology can motivate individuals to take an active role in enhancing own health. The Moodmetric mission is to prevent health issues and related costs caused by stress on an individual and community level. Preventive stress management is equally interesting to insurance companies in relevant fields.

Electrodermal activity measurement provides athletes with new information

Different kinds of physiological measurement systems have been used for a long time in top sports. Wearable devices have made exercise tracking easy for everyone.

Heart rate monitoring is the most used measurement in sports. It was developed by an Australian physician Robert Treffene for swim exercising. In Finland hear rate monitor was invented by the Polar Electro founder, professor Seppo Säynäjäkangas in 1975.

Today there is a huge variety of equipment for hear rate monitoring. The most accurate ones still measure from chest, either with a band or with taped sensors. Wrist worn trackers are comfortable to wear and they have largely displaced chest bands especially with non-professional exercisers. The accuracy of wrist worn trackers has been improved in past years, but it suffers especially at high heart rates.

Heart rate, heart rate variability (HRV) and electrodermal activity (EDA)

Analysing heart rate gives a good view of physical strain. With different algorithms it is possible to understands also recovery, sleep and stress.

Heart rate variability (HRV) has been lately brought up especially in measuring non-physical load. There are challenges, as at high heart rates the algorithms struggle to understand what happens: is the person physically at rest, but nervous (e.g. about a soon-to-start exam), or is it now about physical exercise? Here the accelerometers, present in all of the trackers, are of help. These components can detect whether a person is moving or is at rest, and much more about movement directions and pace.

The electrodermal activity (EDA) measurement brings interesting new information to analyse performance of an athlete. This does not tell about heart, but about sympathetic nervous system activation through sweat gland reactions of skin. Skin is the only organ that is purely innervated by the sympathetic nervous system. The EDA measurement is very sensitive to emotional and cognitive stress, and it has been used in psychological research already for over 100 years. Only lately it has become available for consumers.

The Moodmetric smart ring measures electrodermal activity. The ring is comfortable to wear and it is thus well suited for continuous, long term measurement. Only a sufficiently long measurement period gives a full picture on stress, how it is generated and how recovery happens during weeks, months and even years.

Both top sports, and going after personal goals in exercising benefit of stress load related information. It is good to understand what sources of stress or recovery might affect the performance. For instance, cognitive load of a professional athlete might be less than for someone who need to have a day job to finance the sports career. The professional athlete can probably exercise more, as there is more time for recovery. The results and performance are affected by emotional and cognitive load, if there is no time to unwind.
