Quality sleep is crucial for immune function. During sleep, your body produces and distributes key immune cells like cytokines and T-cells. Aim for 7-9 hours of uninterrupted sleep each night. Create a consistent sleep schedule by going to bed and waking up at the same time daily. Make your bedroom a sleep sanctuary by keeping it cool, dark, and quiet. Remove electronic devices from your bedroom, or at least enable blue light filters in the evening.

Your immune system needs proper nutrition to function optimally. Focus on incorporating colorful fruits and vegetables rich in antioxidants, vitamins C and E, beta-carotene, and zinc. Include foods like citrus fruits, berries, leafy greens, nuts, seeds, and lean proteins. Garlic, ginger, and turmeric have natural antimicrobial and anti-inflammatory properties. Probiotic-rich foods like yogurt and fermented vegetables support gut health, which is closely linked to immune function.

Moderate exercise improves circulation, reduces inflammation, and stimulates the production of immune cells. Aim for at least 150 minutes of moderate activity or 75 minutes of vigorous activity per week. This could include brisk walking, cycling, swimming, or yoga. Exercise also helps reduce stress and promotes better sleep, both of which support immune function.
