Question

12．[1]Have colds and the flu become part of your winter holidays？Develop these easy disease-fighting habits into your life to help stop sickness in its tracks．
[2]Wash your hands and wash them often．When the US Naval Health Research Center conducted a study of 40，000 soldiers who were ordered to wash their hands five times a day，they found that the soldiers cut their incidence of illnesses by 45%．
[3]Be smart about hand-drying in public washrooms．Studies find a shockingly large percentage of people fail to wash their hands after using a public toilet．And every single one of them touches the door handle on the way out．So after washing your hands，use a paper towel to turn off the tap．Use another paper towel to dry your hands，then open the door with that paper towel as a barrier between you and the handle．
[4]Change your toothbrush every three months． You think your toothbrush gets your teeth clean-and it does．But once you've finished brushing，it can be a breeding（滋生）groud for viruses．Most dentists recommend you change your toothbrush every two to three months．It's also a good idea to replace it after you've had a cold or flu．
[5]Use a humidifier．Dry air provides the perfect environment for cold viruses to grow，which is one reason why colds are so much more common in winter．Use a room humidifier，but make sure you change the water daily and clean it every few days．
[6]________________．Hit the gym，join a dance class，or go for a walk if you can handle the colder weather．A recent study found that older women who did 45 minutes of exercise every day，five times a week for a year，were up to three times less likely to get a cold than other women．
