     As AH1N1 flu continues to spread, experts from the World
Health Organization are calling for everyone to practice smart flu
prevention techniques. Besides washing your hands and getting
enough sleep, here are the other 7 ways to keep your body strong
and your immune (免疫) system ready to fight infection.
Avoid Contact with Sick People
     Flu virus is spread when particles (微粒) blown into the air
through a cough or sneeze reach someone else's nose. So if you're
coughing or sneezing, cover your mouth and then wash your     		            
hands, and if you have to be around someone who is sick, try to stay a few feet away from them and avoid
physical contact.
Eat Immune-Boosting Foods
     Keeping your body strong and ready to fight infection is important in flu prevention. Fatty foods can make
you feel lazy, and make your immune system working in an inactive and compromised way. So stick with
whole grains, colorful vegetables, and vitamin-rich fruits.
Avoid Alcohol
     In addition to being a mood calm and pleasant, alcohol is an immune restriction that can actually decrease
your resistance to virus infections like AH1N1 flu. So avoid alcohol to keep your immune system strong.
Drink Enough Water
     Drink 8-10 glasses of water each day to wash out poisonous things from your system and maintain system
in a good state.
Keep Psychically Active
     Adequate exercise-for example walking for 30 to 40 minutes 3 or 4 times a week-supports the immune
system by increasing circulation, speeding the body's oxygen-taking-in, taking away poisonous things through
sweat, and releasing tension and stress. So get moving!
Be Careful of Surfaces
     This is as much a mindfulness exercise as anything else. Be aware of what public surfaces you touch,
when you've shaken hands with someone, or when you're using something like a pen that others have recently
used-and don't touch your face until you've had a chance to wash your hands.
Know When to Get Help
     AH1N1 flu can look like regular flu, so don't feel like you necessarily are infected if you're exhibiting flu-like
symptoms. But do consult your doctor if your symptoms are severe.
