Ritucharya in Ayurveda

The year according to Ayurveda is divided into two kaals:

Aadaan kaal (Uttarayan) (Northeren Solastice)

Visarga kaal (Dakshinayaan) (Southeren Solastice).

This division is done according to the position of the sun. Aadaan means taking away and visarga means giving. In aadan kaal, the sun and wind are powerful. The sun takes away the strength of the people and the cooling qualities of the earth. It is the debialiting period. strength is weakened . In Visarga kaal , the sun releases the strength to the people. The moon is more powerful, the earth becomes cooled due to the clouds, rain and cold wind.

A year consists of six ritus (seasons). Each ritu is two masas (months) long. Three ritus (one semester) form a kaal.

Seasons and Doshas

Vata dosha accumulates during the dry or dehydrating heat of the summer .It becomes aggravated during the rainy season which causes weakened digestion, acidic atmospheric conditions, and gas produced from the earth.

Pitta accumulates during the rainy season due to the acidic conditions of the atmosphere and a weakened digestion. It is aggravated during autumn when the heat returns .This occurs after the cooling spell of the rainy season.

Kapha accumulates during the cold season due to the cold and damp caused by the winds, clouds, and rain. It gets aggravated during the spring when the warm weather liquefies the accumulating Kapha.
