Every human being needs sleep, we all know that. But why do we need it and what happens to our bodies during the sleep? Here is a list that describes the importance of sleep.
- Sleep helps the brain commit new info to memory. When studying It’s always advised to rehearse things before going to sleep.
- Sleep deprivation results in a decrease in immune system function as measured by white blood cells count (they protect the body) and a decrease in the release of growth hormone (needed for production of proteins).
- Sleep helps people maintain healthy emotional and social functioning while we are awake (during the sleep the parts of the brain that control emotions and social interactions are given rest).
- Insufficient sleep leads to impairment of memory and physical performance. If the scarcity of sleep continues, mood swings and hallucinations may develop.
- On tasks used for testing coordination, sleep-deprived people perform as poorly as or worse than people who are intoxicated.
- Chronic sleep shortage may cause weight gain by affecting the way our bodies operate with carbohydrates and by changing degree of hormones that influence our appetite.
