Sleep is food for the brain. When you sleep, important body functions and brain activity occur. A brain that is hungry for sleep will get it, even when you don’t expect it, and this is particularly true for teens. When the teen does not get enough sleep, he is more likely to have an accident, injury or illness.
Sleeplessness can make it hard for him to get along with his family and friends, hurt his school examination scores, or his performance in sports. Most teens need about nine hours of sleep a night — and sometimes more — to maintain optimal daytime alertness. But few teens actually get that sleep regularly, thanks to the early-morning classes, homework, extra-curricular activities, social demands, computers and other electronic gadgets.
In a 2017 study titled 'Sleeping habits among school children and their effects on sleep pattern' authors, A Mishra et al, says that Indian students are also sleeping less than the recommended nine hours a night. There is a change in the sleep pattern of adolescents due to changes in the levels of melatonin produced by the pineal gland. This substance influences the body clock which is getting set into the adult mode. Adults need six to eight hours of sleep.
Teens tend to ‘wind up’ around 7:30 p.m. while adults tend to ‘wind down’ around this time. Teens then tend to stay awake till 2:00 a.m. This is physiology and is called a sleep phase delay and not impertinence!
And asking a teen to share a bedroom with a grandparent can be disastrous. After the age of 60, sleep requirement is only for four to six hours and the sleep phase moves backwards leading to early bedtimes in the elderly.
Sleep is important during the teen years as the growth hormones are produced by the pituitary gland during sleep. Long term memory imprinting also happens during sleep. During this phase of rapid learning by the teen and formation and fixation of pathways in the brain, adequate sleep is critical.
In a 2010 study titled, 'Sleep deprivation in adolescents and adults: Changes in affect', authors Talbot LS et al say sleep deprivation could increase anxiety and depression in children and teenagers. Further, the study states that lack of sleep affects their performance, including their ability to think clearly, react quickly and how they form memories. It makes them irritable and affects their mood too.
Based on this, controversial as it may sound, we need to take a serious look at school schedules and parental expectations to accommodate the sleep needs of young people.
Changing sleep patterns in teens is associated with:
If teens need about 9¼ hours of sleep to do their best and naturally go to sleep around 11:00 p.m., one way for them to get more sleep is for schools to have a later start time. Today, teens’ natural sleep cycle puts them in conflict with school start times. Most high school students need an alarm clock or a parent to wake them up on school days. They are like zombies getting ready for school and find it hard to be alert and pay attention in class. On the other hand, studies in the US showed marked improvement in classroom attendance and alertness during classes, when the start time was pushed back by an hour.

So, teens need to schedule more study time over the weekends, instead of late at night. They should spend more time outdoors with nature if possible, be physically active, eat sensibly and get the required amount of sleep. Then both health and performance can win. Sweet dreams!
