why sleeping is Important ?
Sleep is food for the brain. During sleep, important body functions and brain activity occur.
Skipping sleep can be harmful — even deadly, particularly if you are behind the wheel. You can look bad, you may feel moody, and you perform poorly. Sleepiness can make it hard to get along with your family and friends and hurt your scores on school exams, on the court or on the field.
Remember : A brain that is hungry for sleep will get it, even when you don’t expect it. For example, drowsiness and falling asleep at the wheel cause more than 100,000 car crashes every year.
When you do not get enough sleep, you are more likely to have an accident, injury and/or illness.

Researchers believe that sleep affects learning and memory in two ways: Lack of sleep impairs a person's ability to focus and learn efficiently. Sleep is necessary to consolidate a memory (make it stick) so that it can be recalled in the future.
Sleep deprivation or prolonged restricted sleep results in increasing irritability, worsening mood, and feelings of depression, anger, and anxiety. Some argue thatsleep loss leads to heightened emotional reactivity.
