炎熱的夏天，每天都要洗澡，想想也是件麻煩事。為什么要洗澡呢，如果大家都不洗澡就好了。什么，不洗澡會有生命危險？！來看看為什么。
Think about whats going to happen if you decide to stop bathing：
Youll smell bad.
Your skin and hair gets dirtier and dirtier.
Your chance of infection goes up.
Youll probably itch a lot more， and this could lead to an even higher risk of infection.
You are constantly sweating， even though you may not notice it. There are two kinds of sweat glands all over your body — eccrine and apocrine. The sweat from apocrine glands contains proteins and fatty acids， which make it thick and give it a milky or yellowish color. This is why underarm stains in clothing appear yellowish. It turns out that sweat itself has no odor. Then why， you may ask， is a sweaty person so smelly？ When the bacteria on your skin and hair metabolize the proteins and fatty acids， they produce an unpleasant odor.
There are a number of things that can make a person itch. Anyone can get chiggers or ringworm. Normally， this isnt such a big deal. Get some medicated ointment and you will be fine. But if youre on a bathing hiatus and youre already quite itchy， either one of these conditions could send you into a scratching frenzy. You might scratch so much that you break your skins surface. Now， lets say you have some serious bacteria hanging around in all that grime — perhaps， staphylococcus. If it were to enter your bloodstream through the open scratches， the situation could even become fatal.
