Having a glowing smartphone in your bedroom at night could do more than interrupt your beauty sleep – it could also make you fat, researchers have warned. 新的研究表明，晚上睡觉时在卧室里给手机充电不只会干扰美容觉，还有可能会使人变胖。 They say that our bodies need pitch-black dark to produce the right levels of a hormone involved in regulating the conversion of food and drink into energy. 我们的身体需要在漆黑的黑暗环境下才会分泌正常水平的一种调节食物和饮料转换成能量的激素。 It means ambient light from street lamps can disrupt the release of melatonin and prevent us burning food as efficiently. 这意味着连周围的路灯灯光都会扰乱褪黑激素的释放量，影响身体燃烧食物能量的效果。 But scientists say short-wavelength blue light, which is emitted by some devices when they are charging, is the most disruptive to sleep – and consequently our metabolism. 但是科学家说，一些设备充电时发出的短波蓝光对是睡眠最具破坏性，会影响到我们的新陈代谢。 Although it is not bright enough to light up a room, it still disrupts our bodies, they said. A team at the University of Granada in Spain discovered that injections of melatonin helped combat obesity and diabetes in rats by helping to regulate their systems. 虽然这样的光线不足以照亮房间，但还是会影响我们的身体状况。西班牙格拉纳达大学的一个研究小组发现，给小鼠注射褪黑激素通过帮助调节体内系统能够有助于对抗肥胖症和糖尿病。 |
