Scientists have now found out that blue-light can affect your body clock and sleep patterns if used late in the evening or in the night, which is what most phone addicts do on a regular basis. The light is “Short-wavelength-enriched,” meaning it has a higher concentration of blue light than natural light - and blue light affects levels of the sleep - including the hormone melatonin more than any other wavelength.Changes in sleep patterns can shift the body’s natural clock, also known as the circadian rhythm. This body function controls our wakefulness, alertness and dictate function in the body’s organs.
The hormone melatonin is released late in the evening and it peaks during midnight. By confusing your body clock with irregular light patterns, the hormone melatonin and even tryptophan can be delayed which means it will be harder to get to sleep … and we all love our sleep. Also bright lights can strain and damage your eyes, leading to vision problems and may result in YOU having to wear glasses. Is it really so hard just to turn your phone off?
