【英语专业四级满分听力】睡眠

　　When you worry about needing sleep and twist around, trying to find a comfortable position, youre probably only making matters worse. What happens is that your heart rate actually increases, making it more difficult to relax. You may also have some bad habits that contribute to the problem. Do you rest frequently during the day? Do you think about sleep a lot or sleep late on weekends? Any of these factors might be leading to your insomnia by disrupting your bodys natural rhythm. What should you do then on those sleepless nights? Dont bother with sleeping pills; they can actually cause worse insomnia later. The best thing to do is to drink milk or eat cheese or tuna fish. They are all rich in the matter that helps produce in the brain a neural transmitter that induces sleep. This neural transmitter will help you relax, and you will be on the way to getting a good nights sleep.

　　当你担心需要睡眠时辗转反侧，试图寻找一个舒服的姿势时，你可能只是在增加更多的问题。那会使得你的心跳速度加快，让你更难放松。你可能还会存在一些坏习惯造成这个问题。你是否休息过长时间?你是否觉得在周末睡得太多或者睡得太迟?这些都会破坏你的身体自然节奏，导致你失眠。 你应该在这些夜晚做些什么呢?不要依赖安眠药，它们实际上会造成更严重的失眠。最好的办法是喝一些牛奶或吃奶酪或金枪鱼。它们都富含能使大脑释放促进睡眠的神经物质。这些物质能帮助你放松，让你拥有一个美好的睡眠。
