Immunity tends to decline during winter due to various factors, making the body more susceptible to infections. According to Ayurveda, the concept of Loka Purusha Samya Vada explains the interconnectedness between the universe and the human body. Changes in the environment inevitably influence our bodies, emphasizing the need to adapt our diet and lifestyle accordingly. In winter, climatic changes dry out the mucous membranes, creating favorable conditions for viral and bacterial infections. As a result, ailments like colds, coughs, and the flu become more prevalent. Ayurveda identifies winter as a season where Vata and Kapha doshas increase, necessitating specific dietary and lifestyle measures to maintain balance and immunity.
