Sleep is very important for our physical health and sleep deprivation has been linked to an increased risk of heart disease, kidney disease, high blood pressure, diabetes and stroke. A new study has revealed that you may have a great night's sleep if you put on orange glasses some hours before going to bed. Orange glasses block certain wavelengths of light emitted by electronic screens which hamper our sleep cycle, making it easier for us to sleep.
Researchers revealed that light from the blue part of the spectrum, inhibits the body's production of melatonin, a hormone that helps people fall asleep. A Swiss study of 13 teenage boys showed that when the boys donned orange-tinted glasses, also known as blue blockers and shown to prevent melatonin suppression, in the evening for seven days, they felt significantly more sleepy than when they wore clear glasses.
Experts said, "Older adults may be less affected by blue light, since the yellowing of the lens and other changes in the aging eye filter out increasing amounts of blue light."
