“The most important way to keep your immune system functioning normally is the old-fashioned way that nobody likes to talk about: diet and exercise,” Dr. Mainardi says. “Having a varied diet can be difficult, I do understand that, but it’s definitely worth trying to do and will keep you much healthier in the long run.” So, opt for a rich in veggies, fruits, whole grains and lean proteins diet to protect you from germs.
Working out means more than you think. “As boring as it sounds, exercising regularly and eating healthy are the most significant factors for your immune system,” Dr. Mainardi says. “It’s been proven that people who live more sedentary lifestyles are far more likely to get colds or other infectious diseases.”
