Question

Heat and cold can make pain go away．Heat makes our blood move faster and cold helps our nerves（神经）relax．
If you are in pain because you exercised a lot，your muscles（肌肉）need a lot of blood．Blood helps carry the pain away from your muscles．The more blood that comes and goes，the more pain is taken away．That's why sportsmen like to take a hot shower or sauna after exercising．Also，if a sportsman hurts a muscle，the team trainer will put something hot on the sore muscle．
Cold works if you hit your knee or hurt your ankle（脚踝）．At this time，the injured area may get bigger．This is called inflammation．Cold helps to make inflammation smaller．Cold also makes your nerves relax．Nerves in your body tell your brain about pain．
It's always a good idea to ask a doctor about using heat or cold．Never use too much heat or cold!Put a towel around a hot water bottle or ice before putting it against your skin．If you don't，the heat or cold may hurt your skin．
Now if you ever get hurt while exercising or playing，you know what to do．Use heat or cold to help you!
