1.You Could Feel Sick
可能会感到身体不适
You won't be surprised to know that when you exercise, you raise your heart rate for a period of time. While it's great to get that blood flowing, experts will tell you that it's just as important to "get your heart rate back to a normal level after the workout is over." This is also known in the fitness world as "cooling down."
我们都知道运动时心率会升高。虽然这会加速血液流动，但专家表示，“锻炼结束后让心率恢复到正常水平”同样重要，这在健身界也被称为“降温”。
"After physical activity, your heart is still beating faster than normal, your body temperature is higher and your blood vessels1 are dilated," write the health experts at the American Heart Association. "This means if you stop too fast, you could pass out or feel sick. A cool-down after physical activity allows a gradual decrease at the end of the episode."
美国心脏协会健康专家称：“在体育活动之后，心脏仍然比正常情况下跳动得更快，体温更高，血管扩张。这意味着，如果你太快停下来，你可能会昏倒或感到恶心。运动后的‘降温’会让你在运动快结束时逐渐平静下来。”
