New Study Finds Blue Light from Electronics Causes Sleep Disturbances for Teens

blue light from technology disrupts sleep

If your teen is having a difficult time getting a good night’s rest, making it hard for them to get up in the morning, you may want to make sure electronic devices in their room are turned off at night. According to a recent poll by the National Sleep Foundation, more than half of parents with children ranging from 15 to 17 years of age report their child receives fewer than the recommended 7 hours of sleep per night. Of those surveyed, 68 percent sleep with an electronic device on throughout the night. In addition, sleep quality of 45 percent of children 6 to 17 years of age improved when sleeping with no devices turned on.

According to the results, electronics that emit a blue light affect melatonin levels, especially in teenagers. In fact, investigators of the survey discovered teens are more sensitive to blue lights than adults, even when exposed to only one-tenth of the level that adults are exposed to. This is due to the fact that the electronic lights suppress melatonin levels in teens.

Although any electronic lights at night are noted to cause sleep disturbances, blue light especially hinders a restful sleep. Blue light prevents the pineal gland from releasing melatonin, which is necessary for sleep.

As circadian rhythms naturally shift when children reach adolescence, causing a teens to feel more awake at night, the added electronic blue light only further reduces their desire to sleep.

If you’re noticing your teen is a little more drowsy than usual, it’s time to ensure all electronic devices, such as cell phones, video games, tablets, TVs, and computers are turned off at night. As an added benefit to getting more sleep, a restful night’s sleep is proven to increase grades, achievement tests, and attendance rates. Give your teen the boost they need by enforcing electronics are turned off at night.
