睡覺時開燈引情緒低落

Sleeping in anything other than a completely dark room could lead to depression, research suggests, the Telegraph reports. Neuroscientists at Ohio State University in the US believe that even having a dim light on?-- such as a night light often used in a child's room -- adversely affects the chemical balance and structure of the brain. Such a light appears to interfere with secretion of the hormone melatonin, which helps let the body know it is night time.

英國《每日電訊報》消息，研究表明，睡覺時如果房間不是完全黑暗會導致情緒低落。美國俄亥俄州立大學的神經(jīng)科學家認為睡覺時即使只亮著一盞很暗的燈，就像很多孩子房間里的夜燈一樣，都會打破大腦中的化學平衡和結構。這是因為燈會干擾大腦中的黑激素，而黑激素傳遞信號讓身體知道什么時候是夜晚。
