Over the past decade mounting evidence finds that teens are chronically sleep deprived and subsequently suffering significant health effects. Chronic sleep deprivation is becoming the norm for our high schoolers and is known to cause both mental and physical health challenges. In fact The National Sleep Foundation found that over 85% of high schoolers aren’t getting the 8-10 hours of sleep they need while over 50% of middle school students are already falling behind in their zzzzz’s.
The evidence is in: teens who don’t get enough sleep can have academic challenges, an increase risk for sleepiness-caused car accidents, inattention, risk for overweight, risk for anxiety, greater use of stimulants like caffeine or prescription medications, and mood disorders.
This is a biology thing not a laziness thing. That teenager who can’t get out of bed until 11am on the weekends is just tired and trying to catch up! Puberty changes all sorts of things in our life, one major biologic shift occurs in the brain as children morph into adults. Around the age of 12, instead of naturally falling asleep at 8 o’clock like children in middle childhood, tweens and teens’ sleep cycle shifts about 2 to 3 hours making it a real challenge to fall asleep prior to 10 or 11pm. That means those teens up and awake until 11pm are really just acting their age.
The causes of sleep loss for teens are complex. Early school start times, use of electronics, smartphones, and tablets interfere with sleep as do homework, extra-curricular activities, and sports. But so do misperceptions — the same research that found over 85% of HS students weren’t getting enough sleep also noted that >70% of parents to those tired teens felt their child was getting enough sleep! We have to make sleep a priority in our homes. Read full post »
