Of course you don't want to be sick during your holiday. So what can you do while traveling? There are two things you should 1 : relax and sleep well.
A holiday is a time for relaxing, but very often it is not. There are so many places to visit: shops, parks and temples. You may 2 most of the days walking around these places. This can be very tiring. Do not ask your body to do 3 . A tired body means a weak （虚的弱） body. A weak body gets sick 4 . So take a rest in a nice place. For example, you can 5 a park bench （长凳） in good weather.
Sleep is also important. If you want to stay healthy, you need to get enough sleep. Your hotel room may be 6 or you may want to stay out late at night. Then you should plan to get some sleep during the day. The extra hour can make a big difference.
