Charging computers and cell phones in your bedroom while you sleep may cause weight gain, according to an article published in the Daily Mail. The light produced by a charging computer or phone is enough to disrupt the production of melatonin, the sleep hormone.
Many studies have linked too much light at night with a slowing of melatonin production, and other studies have shown ties between a lack of sleep and weight gain.
Researchers at Spain's University of Grenada found that injecting melatonin in rats helped reduce obesity and diabetes in rats. A new study at Manchester University is studying how regulating sleep patterns might help combat diabetes.
Dr. Simon Kyle, a sleep researcher at Manchester University, told Daily Mail that blue light — the kind phones and laptops produce — is the type of light that is most damaging to sleep, and therefore metabolism. In addition, blue light can also keep your mind active.
"In the couple of hours before bedtime, I try and enforce reduced light conditions - and that means an absence of computers, phones and iPads that emit the blue wavelength light," Dr. Kyle said.
