MADRID, May 20 (EUROPA Press) –
Sleeping in teenagers can be improved by just one week, limiting their night exposure to light-emitting screens on phones, tablets and computers, according to the findings in Lyon, France, at the annual meeting of the European Association for Endocrinology, ECE 2019. The study suggests that by Reducing their exposure to blue light devices emit at night, it improves the sleep quality of adolescents and reduces the symptoms of fatigue, lack of concentration and bad mood, after only one week.
Recent studies have shown that exposure to too much night light, especially in light of the blue falling by smartphones, tablets and computers, may affect the brain clock and the production of the bedroom's hormone hormone, resulting in disruption of sleep time and quality.
Lack of sleep not only causes immediate symptoms of fatigue and poor concentration, but also increases the risk of more serious long-term health problems, such as obesity, diabetes and heart disease. Another work suggested that lack of sleep related to screening time may affect children and adolescents more than adults, but no analysis has fully explored how real life exposure affects adolescent sleep at home. And if it can be reversed.
In this joint study between the Dutch Institute of Neuroscience, Amsterdam UMC and the Netherlands Institute of Public Health and the Environment, the researchers studied the effects of blue light exposure among adolescents at home. Those who spent more than 4 hours a day in front of the screen had an average of 30 minutes of falling asleep later in the night awakening than those who recorded less than 1 hour per day of screen exposure time as well as other symptoms of sleep loss.
Reducing signs of sleep loss
The team conducted a randomized controlled study to evaluate the effects of blue light blocking with glasses rather than screen time during the night and sleep pattern of 25 frequent users. The blocking of the blue light with the glasses and the abstinence from sitting in front of the screen caused the appearance of the dream and awakening 20 minutes earlier, and the reduction of symptoms of sleep loss in the participants, one week
Dr. Dirk Jan Stanvers of the Department of Endocrinology and Metabolism at the WBU in Amsterdam says: "Teens spend more and more time on devices with screens and complaints about common sleep in this age group. These sleep complaints can easily be reversed by reducing night use of the screen or exposure to blue light. According to our data, it is likely that the complaints of adolescents and sleep delays mediate, at least in part, by the blue light of the screens.
"Sleep disorders begin with mild symptoms of fatigue and low concentration, but in the long term we know that sleep loss is associated with an increased risk of obesity," Dr. Stenvers and his colleagues are now interested in. Hyperthyroidism, diabetes and heart disease. "If we can take simple steps to address this problem, we can avoid bigger health problems in the coming years," concludes Stanvers.
