There are many benefits of sleeping well as sleep is essential to our lives. It affects our physical and mental health, and is essential for the health and wellbeing of our body. Deep and restful sleep helps the body to rejuvenate, restore, and regenerate itself. It is the time when our body lowers its energy requirements, the muscles are repaired and revitalized, and our mind memorizes the things we learnt during the day.

Getting peaceful sleep in the night is one of the keys to remain emotionally, mentally, and physically healthy.
