Winter can be divided as either wet or dry winter. Wet winter is characterized by fall in temperature along with high humidity. Environmentally, we see fog and smog during this season. Dry or late winter on the other hand is characterized by absence of fog, smog and presence of chilly airy winds.

Most hypothermia illnesses occur in dry late winter. The transition phase between wet and dry winter is on Lohri. In terms of Ayurveda, it means shifting from Kapha to Vata atmosphere. The onset of dry winter is also the time for accelerated movement disorders in the body. Accelerated hypertension, arrhythmias, paroxysmal atrial tachycardia (PAT), brain hemorrhage, heart attack etc. all occur at the start of dry late winter. Unpublished compilation of data has also shown that maximum temporary pacemakers are also put during this season. The correct lifestyle in this season has been defined in Ayurveda and it involves reducing consumption of stringent, bitter and pungent foods.
