How would your day even go with zero sleep? How do you feel physically and psychologically? Why sleep is given so much importance?
Sleep serves a very important function – recovery. It gives your brain and body time to recover from the stressors. Sleep not only helps with relaxation but also makes you feel more optimistic, alert and stave off diseases. Inside your brain is a peanut-sized structure i.e. Hypothalamus. It consists a group of nerve cells which affects sleep and arousal.
There are 2 basic types of sleep
1. Rapid Eye Movement (REM) sleep – It occurs about 90 minutes after falling asleep.
2. Non-Rapid Eye Movement sleep- It has three stages,
- Stage 1 is changeover from wakefulness to sleep.
- Stage 2 is period of light sleep before deep sleep.
- Stage 3 is period of deep sleep that makes you feel rejuvenated.
Sleep pattern keeps changing as we grow older. There is no particular number as to how much or how many hours of sleep makes you feel refreshed. The matter is about the quality of sleep and how many hours of sleep you feel you need. Research has shown that treating sleep problems can reduce depression.
This Sleep Awareness Week 2022 is March 13-19. Sleep well! Sleep tight!
