While automobile vehicles need preventive servicing every three months, the human body needs it every two months. According to Ayurveda, the seasons change every two months, approximately in the middle of the month. Ayurveda describes these changes and precautions to be taken in great detail. The current makar rashi season, which starts today with sun changing its direction northwards resulting into lengthening of day and shortening of night time needs many lifestyle changes to balance health and prevent diseases. Vata gets aggravated, kapha gets accumulated and pitta gets depleted in this season. In allopathic language, pitta denotes metabolic functions, vata signifies movement functions and kapha stands for secretory functions of the body. Lohri, Makar Sankranti and Pongal are celebrated with khichdi, milk, gur, bhaat, sesame (Til) laddu, light hot food and beverages, etc. all indicating measures to reduce vata and kapha and to increase pitta in the body.
