How do smartwatches measure stress

Smartwatches use heart rate monitors to measure stress. One of them was the stress-causing activity, i.e. is also known as heart rate variability. Heart rate variability measures interval time between the heartbeats. Measuring heart rate is about reading an average number of heartbeats per minute. 

It is stated out, if you have a high heart rate variability, then it’s good. But, a low HRV reading person is associated with stress. 

Also, the people with low heart rate variability are choked of diabetes, heart disease, and cholesterol. 

Let’s understand it using an example. 

Our heartbeat pumps according to our mental and physical activity. If you’re walking around then your heart rate will be normal than a running person. Similarly, a tensed person’s heart rate will be different from a happy person’s. It all happens when our body releases stress hormones known as adrenaline when you are mentally or physically stressed. 

In simple form, stress is when your breath fastens, your muscles tightens, and your heartbeat increases. 

How Do Smartwatches Control Stress? 

Stress can be relieved from any kind of physical activity. Your regular exercise and meditation can help you to recover from severe stress or tension. 

Smartwatches do monitor and also motivate you to be fit therefore it acts as a fitness guide.

Smartwatch monitors the types of stress or disease suffering from, using your heart rate monitor and suggests to you the types of exercise you should indulge in. As a result, the body will release hormones to prepare for a fight.
