Often when it is difficult to sleep, we are led on a television screen or gadget. In fact, this was considered to be increasingly disrupt the rhythm of sleep, even for people who rarely experienced trouble sleeping.
But sleep researcher Glenn Landry said, the choice is fine, as long as you wear sunglasses at least 2 hours before bedtime.
Light blue, or the type of light emitted from electronic devices such as laptops, mobile phones and TV screens may affect the circadian clock, the body's natural system that detects a change from daytime to evening. This system makes the body relax and finally sleepy.
Well, to the effect that no more blue light interferes with sleep, in addition to the circadian system help you work better, Landry advises his clients to wear goggles during the two hours before bedtime.
The goal is to "trick" the circadian clock into thinking that it is time to go to bed.
"From eight o'clock in the evening, two hours before going to bed, wear sunglasses. It aims to avoid any light. By doing so, the body will automatically detect that this is the end of the day."
Interestingly, he also commented, people who rarely get sunlight in the morning also at risk of losing cues to the brain about the differences when to be awake and asleep.
"Another way to avoid insomnia, you can wake up in the morning and bask in the sunshine. Make sure the room exposed to natural light during the day and darken bedtime."
