Hello everyone I will once again look at how blue light can affect children's health and also their daily activities.We will see that when kids spend a lot of time on electronic devices that emit blue light,they will get a harder time in sleeping and therefore parents should keep away the gadgets away 2 to 3 hours to sleep .
Blue light can cause health problems to kids health.Let there be light. Just not blue light. The blue light emitted by our computers and electronic devices is getting a bad rap these days, as some scientists have warned people against exposure to blue light before bed which can trigger alertness, reduce melatonin levels, and delay or disrupt sleep. As a result, we’re seeing a whole new opportunity of consumer products designed to protect us from blue light—such as blue light blocking glasses for computer use, a blue light filter for smart phones, and blue light screen filters for your e-reader.
What Can Parents Do to Protect their Kids from Blue Light?
Many parents urge a digital curfew on their kids, making sure they wind down with device-free time before bed. Some home Wi-Fi systems have parental controls that automatically turn off Internet access to your kids’ devices at a certain time each night. Specialists suggest powering off about one to two hours before bedtime, so the body can increase production of sleep-regulating melatonin.
For older kids who do their homework on a computer at night, blue light blocking glasses can help to filter out the powerful wavelengths. It’s also a good idea to dull the brightness of the computer screen. And for kids who keep on looking at their handheld devices well into the night, apps are available that reduce the screen’s blue light at a certain time each evening (the screen will take on a slightly orange-ish color, for better or worse).
Perhaps the best thing parents can do is practice what they preach, withhold from screen time themselves after a certain time each evening. Then the whole family might reap the merits of better sleep at night, and increased alertness and productivity during the daytime.
