|Sleep is essential for a healthy body and mind. It is a basic human need and without it we would not be able to function properly. People often believe that they can get by with a little sleep but it catches up with you eventually. Getting a good sleep benefits your mood, memory and concentration. It also promotes growth and development, boosts the immune system as well as nervous system.
Understanding the sleep cycle is important to ensure that you get a peaceful, sounder sleep. When you sleep, your sleep goes in cycles between rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep. REM sleep is a basically a light sleep where you will most likely awaken. In REM, you do most of your dreaming and your body does not move much, heart rate increases and your eyes move back and forth. In NREM your body slows down to prepare you for your deepest sleep.
