You asked, Should I exercise when I'm sick?
讀者提問：生病時我應該運動嗎？
If you want to protect yourself from colds and flu, regular exercise may be the ultimate immunity booster.
如果你想預防感冒和流感，經常鍛煉或許可以說是提高免疫力最好的辦法。
Studies have shown that moderate aerobic exercise—
研究表明，適度的有氧運動——
30 to 45 minutes per day of activities like walking, biking or running—
也即每天堅持30--45分鐘的活動，如散步、騎車或跑步——
can more than halve your risk for respiratory infections, partly by increasing circulation of immune cells.
能夠將呼吸道感染的幾率縮小一半，部分通過加快免疫細胞的循環。
But when you feel sick, the story changes.
但你要是生病了，那就另當別論了。
"Exercise is great for prevention, but it can be lousy for therapy,"
“鍛煉對感冒的預防很管用，但對感冒的治療而言就非常糟糕，”
says David Nieman, director of the Human Performance Lab at Appalachian State University.
阿巴拉契亞州立大學人類機能實驗室主任大衛·尼曼說。
Research shows that moderate exercise has no effect on the duration or severity of the common cold, in which symptoms occur from the neck up.
研究表明，適度運動對普通感冒，也即癥狀只在頸部以上部位出現的感冒，持續的時間以及嚴重程度并沒有影響。
If you have the flu or another fever-causing infection, exercise can slow recovery.
如果您患上的是流感或其他發燒引起的感染性感冒，那么運動是會降低你恢復健康的速度的。
Your immune system is working overtime to fight off the infection,
你的免疫系統本來就在超負荷地抵御感染了，
and exercise, a form of physical stress, makes that task harder.
運動，本身就是一種身體壓力，只會讓這項任務變得更加艱巨。
Once your fever has subsided, wait a week before easing back in, says Nieman.
一旦你的燒已經消退，請等一周再慢慢恢復鍛煉，尼曼說。
By the end of the second week post-fever, if you're feeling good, you can return to your usual training.
在發燒后的第二周結束時，如果你感覺不錯的話，就可以恢復平時的訓練節奏了。
