I think we need to stay healthy to prevent the flu and keep as healthy as possible by taking good care of myself. Sleep and nutritional considerations are helpful to prevent the onset of a cold or flu, a healthy lifestyle helps my immune system to be in its best possible shape, giving me the best chance of being able to fight off the onset of a cold or flu.
I need to eat healthily. Healthy foods such as vegetables, fruit, grains, etc. are important in keeping my body's nutrition at its optimum. Processing fatty and sugary foods don't give the immune-boosting protection that healthier food does. Sugary foods can decrease immune function.
Exercise regularly. Exercise has enhancing immune system that can help ward off illness. Overdoing too much strenuous or excessive can leave me prone to illness. I make sure to get adequate sleep every night, get at least seven to eight hours of 

I need to reduce my stress too. Stress can harm the ability of my immune system to work optimally, and people who are stressed tend to catch colds more than less stressed people. Managing my stress is contributing to preventing the flu. Besides, Drinking water may also help wash cold and flu viruses from my throat to my stomach where they cannot survive. Although getting cold doesn't cause a cold or flu (the viruses do), being cold can reduce my stamina and make me feel miserable and fatigued, so I need to stay warm.
In addition, I eat more fruits to get vitamin C that might help me prevent the common cold, and I will also drink more milk, this will help me healthy and stronger to prevent the cold

Environmental protection activities. I really enjoy doing this. Because when we finish protecting the environment, if the environment is good, we can protect our health. So I have protected the environment.
