Tis the season for colds and flu, but there are science-backed ways to boost your immunity and stay healthy. Changes in weather, high stress levels, and poor diet can weaken your immune system, making you more susceptible to illness. To strengthen your body’s defense against germs and viruses, consider increasing your fiber intake, adding a probiotic to your daily routine, decreasing refined sugar consumption, exercising regularly, and eating a well-balanced diet. These strategies can help support your immune system and keep you feeling your best throughout the winter months.
