During the daytime,many people are busy using their cell phones. They only have time to charge (充电) them at night when they are asleep. But scientists have warned that having a glowing smartphone in your bedroom at night could not only affect your sleep,it could also make you fat.
When darkness falls,our bodies begin to produce a hormone (荷尔蒙) called melatonin (视黑激素) . K helps our metabolism (新陈代谢) so that our bodies can change food and drink into energy. When the sun rises,melatonin reduces. This light-dark cycle is good for our health.
But if you charge your phones when you are asleep,the phone releases blue light. Although it is not bright enough to light up a room,it can affect your sleep. Therefore,it slows down your metabolism and influences your body to digest (消化) food. This may make you fat.
"Blue light is bad for health because it keeps the mind buzzing," Simon Kyle,a sleep scientist at Manchester University,told the Daily Mail. And there is strong scientific data to show the connection between sleep interference (干扰) and people's health.
Earlier this year,leading scientists from universities including Oxford,Cambridge and Harvard,warned that a lack of sleep could cause serious problems,such as cancer,heart disease and obesity.
Kyle suggested turning off smartphones and desktop computers a few hours before going to bed. This helps to reduce people's exposure (暴露) to artificial (人工的) light.
