TOO MUCH SLEEP OR TOO LESS SLEEP: WHAT WORKS?
Sleep is important especially in growing and developing children. Not only does sleep provide an opportunity for the body to physically rest, it’s the time during which, according to recent research, the brain consolidates or reinforces what a child has learned or observed during the day.
Not surprisingly, sleep deprived children tend not to do well at school. Other symptoms of sleep deficiency in children include the obvious ones such as fatigue and inattentiveness. There can also be less obvious symptoms including irritability, impatience, fussiness and even aggressive behavior. Teenagers also need to get enough sleep. Just because they are older does not mean they can get away with less sleep. In fact, most adolescents actually get much less sleep than they need.
Staying up late a few nights in a row and then trying to catch up on the weekend does not help. In other words catch up sleep does not count. So, if on average, one seems to get enough hours of sleep over a week, but it is done so by catching up on weekends to make up for week nights of little or less than adequate sleep, it will not work. What counts is getting enough sleep each and every night.
Thus, try taking short breaks and maintaining adequate sleep routine which will help you to remain alert and responsive, studying till late or getting up early is immaterial. Remember though the amount tends to decrease with age, still the average adult needs at least 7 to 8 hours of sleep per night.
