Ayurveda, the ancient science of life, has never placed primary focus on treating diseases but rather on sustaining health and avoiding disease by maintaining a healthy lifestyle and diet. Its very foundation is in the principle Swasthyashya Swasthya Rakshanam, which means "sustaining the health of the healthy." This reinforces Ayurveda's preventive focus. At the center of this belief system is Ritucharya, or seasonal routine, which regulates diet and lifestyle in relation to the natural cycles.
Scientific research, including that conducted in 2015 at the University of Cambridge, aligns with Ayurveda's approach to immunity, with it showing seasonal influences affect immune response by changing gene expression, blood profile, and metabolism. Noting this, Ayurveda recommends seasonally specific diets for enhancing the natural immunity of the body. Let's understand the sagacity of eating in relation to the season and how this benefits general health.
Uttarayana, which takes place from mid-January to mid-July, is the sun's rise and intensified rays. The body at this time is subjected to added dryness and dwindling power. The intense sun drains the body of moisture, causing disturbances in energy levels and metabolism. It is necessary to eat wholesome, easily digestible foods like:
Dakshinayana, which extends from mid-July to mid-January, is characterized by the sun's fall, cooler climates, and greater vigor in the human physiology. The atmosphere is more anabolic, i.e., the body is able to regenerate and develop immunity efficiently. Ayurveda suggests that during this season, one must include in the diet plenty of:
Spring is known for the preponderance of Kapha dosha, which may bring about slow digestion and congestion. To balance them out, Ayurveda advises:
In summer, Pitta dosha prevails, causing excessive body heat. Cooling foods and fluid intake are essential during this season:
Fresh fruits like melons, cucumbers, and pomegranates
Dairy items like buttermilk and ghee to counteract internal heat
Fluids like coconut water and herbal teas
Avoiding spicy, oily, and salty foods that increase body heat
Rainy season enhances Vata dosha, causing digestive disturbances and impaired immunity. Ayurvedic advice is:
Autumn increases Pitta dosha, and hence it is necessary to eat foods that balance heat:
It is a Kapha-season in winter that requires warming as well as immunity-inducing food:
Ayurveda recognizes three main seasonal influences on the body's doshas:
Caya (Accumulation): Normal accumulation of doshas in their primary sites, e.g., Vata in intestines.
Prakopa (Aggravation): Doshas overflow and deposit in secondary locations of the body, resulting in imbalances.
Prashamana (Alleviation): Doshas balance with ideal diet and seasonal regulation.
