Summer is the perfect time to relax.As you plan for your trip,here are some tips on how to protect yourself.

    Fight against the mosquitoes in the hot spots.

    There are many mosquito-borne illnesses in tropical regions,which are traditionally vacation hot spots. Therefore,mosquito repellent（驱蚊剂）that contains DEET should be an essential item in your travel bag.

    In lesser-developed countries there is less equipment for clean water and public health.If you can't avoid unhealthful water,make sure you bring along a tea or coffee—making pot that will boil water for you.You'd better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

    Always protect your feet.

    It's best to wear slippers in the shower,but if you must be barefoot,put a towel down on the floor.You should never walk barefoot in any area of a foreign country,including your hotel room.

    Be sure to eat safe fruits.

    They may have been washed in the same water,or wiped with the same rag used to clean work surfaces in kitchens.The best advice is to bring your own peeler（削皮器）so that you know that something clean has been applied to the fruit.

    Enjoy the smell of roadside stands,not the food.

    Unless the food is piping hot when served,it's best to stay away from roadside stands,no matter how good the smell of the food might be.If you are concerned about whether a restaurant is clean,order the food to go.
