Charaka Samhita, Sutrasthana 6.12
Hemante balam utkrishtam — Strength is at its peak in Hemanta. Agni is most powerful. One should eat the most nourishing foods — sweet, sour, salty, and fatty — to build the Bala and Ojas that sustain the body through warmer seasons ahead.

Classical Hemanta regimen

Diet

Maximum nourishment

Sweet, sour, and salty tastes with oily, heavy foods specifically indicated — strong Agni can process what would create Ama in weaker seasons. Milk with ghee, sesame preparations, Urad dal, wheat. Cook everything.

Rasayana

Primary Rasayana season

Hemanta is the optimal season for extended Rasayana protocols. Chyawanprash specifically documented for beginning in Hemanta. Strong Agni ensures heavy preparations are fully absorbed.

Exercise

Maximum intensity

The season for maximum exercise intensity — vigorous training produces maximum Bala-building. Strong Agni processes metabolic products without accumulating Ama.

Building for the year ahead
The Bala and Ojas built in Hemanta and Shishira sustain the body through Grishma depletion and Varsha vulnerability. Winter building is the classical preventive strategy for the challenging seasons ahead.
