Seventy percent of the people who catch a cold feel better within a week, but it is not unusual to have the common cold for as long as two weeks.

Why does your cold seem to be staying longer than it should be? Here are some possible reasons.

Sleep plays an important role in our immune system(免疫系统). In fact, this year a study showed that people who got less than seven hours of sleep per night were nearly three times more likely to catch a cold than people who slept for eight hours or more.

Water plays an important part in our body. If your cold won't go away, think about drinking more hot water.

In fact, taking too much medicine can make things worse.

The common cold can easily be mixed with other illnesses. Often, people believe they've had a cold for a few weeks and may not realize that they aren't getting better because they're being treated for the wrong illness.

People ask “Should I exercise when I have a cold?” all the time. The answer is usually yes. But do it at a low level and listen to your body. For example, try taking a walk instead of running five miles. If you do it at a high level, it'll do more harm to your body. It'll also make the cold stay longer.
