The study also showed that filtering out the blue light reduced symptoms of fatigue, lack of concentration and bad mood.

Teenagers should wear sunglasses to bed to block out sleep-disturbing blue light from phones, computers and tablets, a study suggests.

A study by researchers in the Netherlands found that wearing glasses that filter out the blue light has virtually the same impact on sleep as turning off devices entirely. “Here we show very simply that these sleep complaints can be easily reversed by minimising evening screen use or exposure to blue light.

Similarly, the study also showed that filtering out the blue light reduced symptoms of fatigue, lack of concentration and bad mood, after just one week.

Google tends to push stories for left-leaning readers, study showsNewsrooms with left-wing readers get five times more views on Google’s Top Stories box compared to newsrooms with right-wing readers duh The good news , NATIONAL post , is that thinking people can filter it all and make an informed position.
