It is very important to boost our immune system during winter. You wash your hands 10 times a day and stop touching your face. To improve your health and avoid illness and cold.
To be immunologically fit, you need to be physically fit.
By boosting your blood flow, exercise gets them moving so they can carry out their surveillance tasks and locate and destruct other body components. Do at least 150 minutes of moderate aerobic activity (hiking, gardening, cycling) or 75 minutes of vigorous aerobic activity (running, brisk swimming, an aerobics class) or any other form of physical activity per day.
Exercising and eating well
The biggest thing is hygiene. So wash your hands, and sneeze and cough into your elbow. No one can completely avoid getting sick, not even top immunologists. A healthy lifestyle will ensure your defenses are as good as they can get!
