It is critical to take care of your body and avoid illness regardless of your age. However, something as basic as the flu or a regular cold might worsen and cause difficulties if you’re 65 or older. Pneumonia, bronchitis, an ear infection, or a sinus infection are examples of secondary infections. If you have a chronic illness like asthma or diabetes, a respiratory ailment might exacerbate your symptoms. As a result, it’s critical to make healthy choices in order to improve your immune system and lower your risk of sickness. Physical activity boosts the immune system. The more you move, the better your body can fight infection and inflammation. It is not necessary for you to engage in a strenuous exercise. Bike riding, walking, swimming, or low-impact aerobics are all options. If you’re able, do 20 to 30 minutes of moderate-intensity activity each day to attain the recommended weekly total of 150 minutes. Lift weights or practice yoga to improve your muscles. Change up your workout program to see what works best for you. Some nutrients aid in the maintenance of a healthy immune system. Always check with your doctor before taking a supplement, especially if you’re on a prescription medicine. Calcium, vitamin D, vitamin B6, and vitamin B12 are some of the vitamins they may recommend. To strengthen your immune system, take supplements or multivitamins as directed.
