Winter can be divided into wet and dry winter. Wet or early 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 the day of Lohri. In terms of Ayurveda, this 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, brain hemorrhage, heart attack etc. all occur when dry late winter starts.
The correct lifestyle in this season has been defined in Ayurveda and it involves reducing consumption of stringent, bitter and pungent foods
