Below is some advice on how to prevent colds and flu.
| 8 Ways to Avoid Colds and Flu 1. Wash your hands and wash them often The US Naval Health Research Center conducted a study of 40,000 volunteers who were ordered to wash their hands five times a day. The volunteers cut their incidence of flu by 45 percent. 2. Wash your hands twice every time you wash them Researchers at Columbia University found one handwashing had little effect, even when using antibacterial soap. So wash twice if you’re serious about preventing colds. 3. 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 ground for germs. Most dentists recommend you change your brush every two or three months. It’s also a good idea to replace it after you’ve had a cold or flu. 4. Sneeze and cough into your arm or tissue (纸巾) Whoever taught us to cover our mouths when we cough or sneeze got it wrong. That just puts the germs right on our hands, where you can spread them to objects — and other people. Instead, put your arm over your mouth and nose when you sneeze or cough if a tissue isn’t handy. It’s pretty rare that you shake someone’s arm, after all. 5. Stop blaming yourself when things go wrong Believe it or not, blaming yourself makes you more likely to catch a cold! Researchers found that even those who had control over their work were more likely to begin sneezing if they lacked confidence or tended to blame themselves when things went wrong. Such attitudes make people more stressed on the job, and stress, as you know, can challenge your immune system. 6. Once a day, sit in a quiet, dim room, close your eyes, and focus on one word Meditate (冥想). It is a proven way to reduce stress. Studies have shown that stress weakens your immune system. In fact, people with high stress levels have up to twice the number of colds as non-stressed people. 7. Get moving Ride a bike, join a dance class, or go for a walk. A study found that older women who did 45 minutes of gentle exercise, five times a week for a year, were up to three times less likely to get a cold than women who took little exercise. The researchers found that the exercisers’ immune system was strongest in the last three months of the study. 8. Leave the windows in your house open a crack You don’t have to keep all of them open, but one or two in the rooms in which you spend the most time. This is particularly important if you live in a newer home, where fresh circulating air has been the victim of energy efficiency. A bit of fresh air will do wonders for chasing out germs. |
