Hints for Good Health
Do you have trouble sleeping at night? Then maybe this is for you. When you worry about needing sleep and toss and turn trying to find a comfortable position, you're probably only making matters worse. What happens when you do that, 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 get virtually no exercise, or do you exercise strenuously late in the day? Are you preoccupied with sleep, or do you sleep late on weekends? Any or all of these factors might be leading to your insomnia by disrupting your body's natural rhythm. What should you do, then, on those sleepless nights? Don't bother with sleeping pills, they can actually cause worse insomnia later. The best thing to do is drink milk or eat cheese or tuna fish. These are all rich in amino acids and help produce a neurotransmitter in the brain that induces sleep. This neurotransmitter will help you relax, and you'll be on your way to getting a good night's sleep. Until tomorrow's broadcast, this has been another in the series "Hints for Good Health".
晚上睡不着觉？那么下面说的或许能帮到你。如果你一边担心睡不够，一边还辗转反侧试图找到那个舒服的姿势，或许你只是让情况变得更糟。因为那么做实际上只能使你的心跳加快从而更难以入睡而已。 你可能有的一些坏习惯也会引起失眠。比如白天时不时地休息、几乎不做运动或是在晚上进行了太过激烈的运动。又比如之前睡得太多或者周末起得太晚。这些因素中的任何一个或者几个都会打乱你身体原本的生物钟而造成失眠。 那在这些失眠的夜晚你该怎么办呢？千万不要去尝试安眠药，因为服用它们只会在以后引起更严重的失眠。最好的办法是喝些牛奶，或者吃些芝士或是吞拿鱼。这些富含氨基酸的食物可以产生帮助大脑诱导睡眠所需要的一种神经递质。这种神经递质有助于你放松并好好地睡上一觉。 明天的广播将会继续“健康贴士”的系列节目。 ——译文来自: tan13
