I know, you stopped listening to your parents around age 12, but every now and again, they do have useful advice<\/a> for you:<\/p>\n

\n

Only 5% of high school seniors get eight hours of sleep a night. Children get an hour less than they did 30 years ago, which subtracts IQ points and adds body weight.<\/p>\n

Until age 21, the circuitry of a child\u2019s brain is being completed. Bronson and Merryman report research on grade schoolers showing that \u201cthe performance gap caused by an hour\u2019s difference in sleep was bigger than the gap between a normal fourth-grader and a normal sixth-grader.\u201d In high school there is a steep decline in sleep hours, and a striking correlation of sleep and grades.<\/p>\n

Tired children have trouble retaining learning \u201cbecause neurons lose their plasticity, becoming incapable of forming the new synaptic connections necessary to encode a memory. … The more you learned during the day, the more you need to sleep that night.\u201d<\/p>\n

The school day starts too early because that is convenient for parents and teachers. Awakened at dawn, teenage brains are still releasing melatonin, which makes them sleepy. This is one reason why young adults are responsible for half the 100,000 annual \u201cfall asleep\u201d automobile crashes. When Edina, Minn., changed its high school start from 7:25 a.m. to 8:30 a.m., math\/verbal SAT scores rose substantially.<\/p>\n

Furthermore, sleep loss increases the hormone that stimulates hunger and decreases the one that suppresses appetite. Hence the correlation between less sleep and more obesity.<\/p>\n<\/blockquote>\n

So, even though the temptation is to stay up as late as you possibly can . . . don’t. You’ll actually notice the difference the next day.<\/p>\n","protected":false},"excerpt":{"rendered":"
