Chan School of Public Health, vitamin C stimulates the production of white blood cells, which are key to fighting infections; while the National Institutes of Health notes that zinc is crucial for normal immune response and helps the body combat viruses and bacteria.
Eat more citrus fruits, garlic, spinach, and yoghurt, along with zinc-rich foods such as nuts and seeds.
Drinking water helps flush toxins out of your body, which aids in maintaining a strong immune system. The National Academies of Sciences recommends that men should drink about 3.7 litres per day and women, about 2.7 litres.

Chronic stress can weaken the immune system. Practices like meditation, yoga, and deep breathing exercises can help manage stress, as per the American Psychological Association.

Supplements like Vitamin D, C, and Zinc can help fill nutritional gaps, especially during winter months. A study in Nutrients shows that vitamin D plays a critical role in activating immune defences.
Good hygiene practices, such as regular handwashing and keeping surfaces clean, help prevent infections from spreading.
The Ministry of Health and Family Welfare and the Indian Council of Medical Research both recommend getting seasonal vaccines like the flu shot, especially for high-risk groups such as the elderly, young children, and individuals with chronic conditions.
