How to prevent getting sick easily?

Wash your hands. By far the best thing that you can do to prevent getting sick easily is washing your hands. General health practices like this are often overlooked but can make a major difference. This is especially true during seasons where a lot of your friends or coworkers may be sick. A flu vaccine can also be a great way to stay healthy during flu season and is strongly recommended.
Six Steps. Eat well: whole grains, half your plate with fruits & veggies, lean meat or nuts/beans, drink 6-10 glasses of water. Get moving 30-60 minutes every day. Sleep well. During sick season, wash your hands. Balance work/play [easy to say, hard to do!]. Make friends.
