In teenagers, sleep problems could be reversed in one week by limiting screen use in the evening.
It is known that blue spectrum light, such as that emitted by cell phones, tablets and computer monitors, inhibits brain secretion of melatonin, resulting in alterations to the body’s internal clock, delayed sleep onset and disruptions in sleep quality. This, in turn, can not only lead to daytime fatigue and poor concentration, but can also increase the risk of more serious long-term health issues such as obesity, diabetes, and heart disease.
A new study shows that by simply limiting their exposure to blue-light emitting devices in the evening, adolescents can improve their sleep quality and reduce symptoms of fatigue, lack of concentration, and bad mood, after just one week.
