New Delhi:It is very common during the winter and monsoon seasons for us to be more susceptible to various infections. According to Ayurveda, a year is divided into 2 kaalas i.e., Uttaryana and Dakshinayana. Each kaala consists of 3 seasons, and so 6 seasons per year with each season persisting for about 2 months.
Uttaryana Kaala (14 January to 14 July)
Shishir Ritu (Winter) Mid- January to Mid- March
Vasant Ritu (Spring) Mid- March to Mid-May
Grishma Ritu (Summer) Mid- May to Mid- July
Dakshinayana Kaala (14 July to 14 January)
Varsha Ritu (Monsoon) Mid- July to Mid- September
Sharad Ritu (Autumn/ Fall) Mid- September to Mid- November
Hemant Ritu (Late Autumn/Pre-Winter) Mid- November to Mid- January
Out of these 6 seasons, Shishir Ritu (winter) extending from Mid-January to Mid-March is a period that remains cold and windy.
Ritusandhi: 'Ritu' means season and 'Sandhi' means junction. It Is a junctional period consisting of the last 7 days of the previous season and the first 7 days of the next season. During this period, our body is prone to infections.
