I need to eat healthily. Healthy foods such as vegetables, fruit, grains, etc., are an important part of keeping my body 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. Overdo too much strenuous or excessive can leave me prone to illness, too. I make sure to get adequate sleep every night, get at least seven to eight hours sleep nightly
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. Manage my stress is contributing to prevent the flu. Beside, 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 actually cause a cold or flu (the viruses do), but 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 be help me healthy and stronger to prevent the cold
