These glasses reduce the impact of smart phones on sleep .. Learn about technology
LONDON [Reuters] – Protective glasses that block blue light from smartphones can help technology-crazed teenagers sleep better at night, researchers said on Tuesday.
Dutch researchers studying the effects of screen time on adolescent sleep patterns found that those who spend more time on their phones are more likely to suffer at bedtime, but taking action in the evening and shutting down the screen before sleep has helped reverse these effects. .
A similar effect has been achieved by wearing special glasses that prevent blue light, which is believed to disrupt the body's internal clock.
Sleep disturbance affects concentration and memory. This can interfere with children's learning, but in the long run it is also associated with higher rates of obesity, heart disease and cancers, which makes the impact of smartphones an important area of research.
The researchers studied a group of 55 teenagers between the ages of 12 and 17, divided between screen users more frequently and less, and found that those who spent four hours or more using screens every day took about half an hour longer night to sleep than those who used screens For an hour or less, this group suffered from more intermittent sleep and took longer to wake up in the morning.
Blue light, which mimics daylight and sleep, can interfere with the prevention of melatonin production, so the results suggest that wearing blue light goggles may reduce the effect of repeated screen use on adolescent sleep. "
