New York, May 24 (ANI): Using your tablet or smartphone before bed can suppress quality sleep, thus putting you at risk for health problems, a new study suggests.
If you want to improve your sleep, researchers advise shutting off your tablet well before bedtime.
Nighttime exposure to LED rays illuminating from tablets, computers, TVs, and smartphones can disrupt your body's natural rhythms, and raise your risk for not only sleep loss but health problems, the report said.
Artificial light can prevent quality sleep by slowing the activity of neurons that induce sleep, activating those for wakefulness, and suppressing the sleep hormone melatonin, the New York Daily News reported.
"Technology has effectively decoupled us from the natural 24-hour day to which our bodies evolved, driving us to go to bed later," lead author Dr. Charles Czeisler, of Harvard Medical School, wrote.
Czeisler claims that a decline in the number of hours slept per night brings a host of health risks, including obesity, diabetes, depression, and heart disease, as well as concentration problems in children.
A study from Rensselaer Polytechnic Institute's Lighting Research Center in the US found that looking at a backlit screen, like those on iPads and other tablets, can lead to sleeplessness.
The study is published in the journal Nature. (ANI)
