1) To know if you are getting enough sleep. Most people need at least six hours of sleep for normal memory and brain function.
2) To create a healthy routine. You can program yourself to sleep at the same time every night and wake up at the same time each morning.
3) To prepare yourself in case you get less sleep etc.

How do smartwatches measure sleep exactly?
Using the actigraphy process (don’t mind the technical term, we got you ahead -;), your tracker translates your wrist movements into sleep habits. It is necessary for the brain to respond to REM (Rapid Eye Movement) sleep waves, movement of the eye, and breathing in order to determine whether it is light or deep REM sleep.
Dangers of not having enough sleep
Sleep tracking may seem unimportant but it is not. Knowing if you are sleeping enough could benefit your general health and improve your relationships with others. Limited sleep on the other hand may result into:
- Lack of concentration
- Excessive fatigue
- Impaired or lowered immune system
- Weight gain
- That is how smartwatches measure sleep, so please endeavor to sleep responsibly by having as much sleep as you can.
