Of course you do not want to spend your vacation sick (生病的) in bed. So what can you do to stay in good health when traveling? There are some things you should remember when you travel: relax, sleep and eat well.
A vacation should be a time for relaxing but very often it is not. Think about what you do when you are traveling. There are so many places to visit: museums, shops, parks ... You may spend most days walking around these places. This can be very tiring. Do not ask your body to do too much. A tired body means a weak (虚弱的) body. And a we
ak body gets sick easily. So sit down for a few hours in a nice and quiet place.
Sleep is also important. If you want to stay healthy you need to get enough sleep.Your hotel room may be noisy or the bed may be uncomfortable. You may not get enough sleep f
or other reasons. You may want to stay out late at night. Then you should plan to sleep for an hour during the day. That extra (额外的) hour can make a big difference.
At last, if you want to stay healthy, you must eat well. That means eating the right kinds of food. Your body needs fresh fruit and vegetables, and some meat, milk or cheese (奶酪).
So, remember this: if you want to e
njoy your vacation, take good care of yourself. Give your body some rest (休息). Get enough sleep and eat good, healthy food.
