Bedwetting
Millions of kids and teenagers from every part of the world wet the bed every single night. It’s so common that there are probably other kids in your class who do it. Most kids don’t tell their friends, so it’s easy to feel kind of1 alone, like you might be the only one on the whole planet who wets the bed. But you are not alone.
The fancy name for bedwetting is nocturnal enuresis. Enuresis runs in families.2 This means that if you urinate, or pee, while you are asleep, there’s a good chance that a close relative also did it when he or she was a kid. Just like you may have inherited your mom’s blue eyes or your uncle’s long legs, you probably inherited bedwetting, too.
The most important thing to remember is that no one wets the bed on purpose4. It doesn’t mean that you’re lazy or a slob. It’s something you can’t help doing. For some reason, kids who wet the bed are not able to feel that their bladder is full and don’t wake up to pee in the toilet. Sometimes a kid who wets the bed will have a realistic dream that he’s in the bathroom peeing — only to wake up later and discover he’s all wet6. Many kids who wet the bed are very deep sleepers. Trying to wake up someone who wets the bed is often like trying to wake a log —they just stay asleep.
Some kids who wet the bed do it every single night. Others wet some nights and are dry on others. A lot of kids say that they seem to be drier when they sleep at a friend’s or a relative’s house. That’s because kids who are anxious about wetting the bed may not sleep much or only very lightly. So the brain may be thinking, "Hey, you! Don’t wet someone else’s bed!" This can help you stay dry even if you’re not aware of it.
译文：尿床
每天晚上全世界会有数百万的孩子尿床。尿床现象如此普遍，以至于你们班里也可能有别的孩子也尿床。大多数孩子不会把自己尿床的事告诉朋友，因此很容易感到你是独自一人，好像全世界只有你一个人尿床。但你并不是一个人。
尿床的学名是夜间遗尿。遗尿在家族中代代相传.也就是说，如果你有尿床的毛病，很可能你的近亲小的时候也尿床：正如你的那双蓝眼睛可能遗传白你母亲，或者你的两条长腿遗传自你的叔叔，你尿床也可能是遗传所致。
很重要的一点是没有人会故意尿床。尿床并不意味着你懒惰或是粗俗。这是件身不由己的事。因为某些原因，尿床的孩子感觉不到他膀胱已满而起来去上厕所。有时尿床的孩子会梦见自己真的在卫生间撒尿.只是等醒来时才发现自己已经湿透了。许多尿床的孩子都睡得很沉，想要叫醒一个尿床的孩子就像要叫醒一根木头——他就是醒不过来。
有些孩子们每个晚上都尿床，另一些孩子则有时尿有时不尿。很多小孩说，他们在亲戚或朋友家过夜时好像就不会尿床。这是因为他们因担心尿床而睡得不多或是睡得不熟.他们的大脑可能在想：“嗨，可不能尿湿了别人的床!”尽管你自己并未意识到这一点，这种想法却能帮助你抑制尿床。
