How Does Stress Monitor Work in A Smartwatch? Is It Reliable?

How Does Stress Monitor Work in A Smartwatch?

Wearables have made some strides in monitoring how stressed we are. They have also monitored our stress levels, with Garmin, Apple, Fitbit, and Google on board. Stress can happen to all of us, whether from certain situations in our lives or just a hectic day at work.

But it can affect our health and lives, so stress detection and coping techniques are already prevalent in wearables. Wearables are also using these physiological measurements to offer us advice on how to cope with stress.

Stress has disrupted the lives of people these days. It is imperative to monitor the stress level to stay healthy and keep the mind calm. Many fitness bands and smartwatches have a stress monitoring feature that precisely measures your stress levels. The following article discusses how it works, how accurate it is, and the famous smartwatches with stress monitoring features.

What is stress level monitoring? Is it significant?

Stress is the physical or mental tension that negatively influences people’s minds and health. It is a human reaction that may arise from overthinking or worrying about something. The typical symptoms of stress are fatigue, headache, irregular sleep schedule, higher than normal blood pressure, heart disease, aging, obesity, etc. If an individual stays under stress for a prolonged period, it can severely influence their body and mind.

Two kinds of hormones, cortisol, and Adrenaline, facilitate stress in the body. In situations of high stress, the Adrenaline hormone overflows into the veins. This causes the blood pressure and heart rate to increase suddenly. Moreover, the blood influx in the muscles increases the body’s glucose level. Also, the eyes’ pupil becomes broader.

According to the WHO, stress is an “Epidemic of the Twenty-first Century.” It is helpful to measure the stress level because it informs you to stay calm and unwind your body to prevent health concerns.

Working of Stress Monitor in smartwatches or fitness bands:

For a few years, fitness trackers have been used to measure stress levels depending on an abrupt rise in heart rate. But this practice was not precise because the heart rate can increase and decrease during a workout or while performing any activity.

Currently, most smartwatches employ Heart Rate Variability (HRV) technology to assess stress. HRV measures the difference in time between every heartbeat. The autonomic nervous system (ANS) of the body regulates this difference. It automatically regulates blood pressure, heart rate, digestion, and breathing.

HRV is not identical to heart rate (BPM). A higher HRV is safe, whereas a lower HRV denotes stress, fatigue, and thirst. Certain smartwatches from the leading brands are implemented with dedicated sensors to identify the stress level.

For example, the Fitbit Sense comes with an Electro Dermal Activity (EDA) sensor, which detects stress through electrical variations in the skin’s sweat level. You must put your palm on the watch dial for two minutes to use this sensor. Also, it measures other health stats like workout activity, sleep, and heart rate to determine how much stress impacts your body.

How do smartwatches assist in decreasing stress?

All the smartwatches are implemented with the “Stress Monitoring” feature that includes a Breathing Exercise mode. This feature relaxes the body via extended breathing sessions. Ultimately, it reduces stress levels.

If the smartwatch has automatic stress monitoring, it automatically notifies you when your body has a high-stress level. Moreover, it will encourage you to perform breathing exercises to decrease stress.

Certain smartwatches help you choose the breathing exercise’s duration and intensity. Hence, when stressed, you can use easy breathing exercises with inhaling and exhaling stimuli to relieve your body.

Instead, you can carry out certain simple activities like watching positive content, going on a walk, drinking water, etc., to alleviate the stress. So, it calms your mind in stressful situations.

Do smartwatches reliably measure stress levels? How precise is it?

With constant technological evolution, smartwatches are implemented with the latest stress measurement methods like EDA and HRV. Most budget smartwatches are implemented with HRV instead of EDA due to cost.

As per specific reports, HRV can detect stress with 90% accuracy; the technology is constantly improving. Therefore, the stress level data on smartwatches is reliable to a fair amount.
