Ritucharya is the Ayurvedic practice of changing what you eat, how you sleep and how you move as the seasons turn. The classical texts describe six seasons, written for the climate of northern India — and anyone who has lived through a Chennai May knows the city does not follow that calendar.
What carries over is the principle, not the calendar. Chennai really has four stretches that matter: a long, humid summer, the south-west monsoon months, the north-east monsoon that brings most of the city’s rain, and a short, mild cool season. Here is how to read each of them.
The classical idea is that each dosha builds up quietly in one season and is provoked in the next. Heat drains strength and lets Vata gather; the rains weaken digestion and stir Vata further; the heat that follows the rains brings Pitta out; and the cool, heavy months gather Kapha. Routine is adjusted to meet each change before it becomes a complaint.
The texts also describe ritusandhi, the junction between two seasons — roughly a week either side of the change — when habits are shifted gradually rather than overnight. In Chennai the junctions are easy to feel: the first sticky week of March, the first heavy rain of October.
Your constitution changes how hard each season lands. Someone with a lot of Pitta tends to struggle in May; someone Kapha-heavy tends to feel the damp months more. The dosha quiz gives you a rough idea; a consultation gives you a reliable one.
The classical summer, Grishma, is a dry heat. Chennai’s is a wet heat, peaking in the Agni Nakshatram weeks of May, and the difference matters: you lose water and salt through sweat while the damp air leaves you feeling heavy and slow. Appetite drops, and that is normal rather than something to fight.
Air-conditioning adds a twist the texts never had to consider. Moving several times a day between a chilled office or car and the heat outside is hard on the sinuses and the joints, and it is often why a summer cold appears in the hottest month. Keep a light layer for indoors, and give yourself a few minutes in the shade before stepping from one into the other.
One caution before the list: if you have kidney disease or heart failure, your fluid and potassium limits come from your physician, not from seasonal advice — tender coconut water is high in potassium.
Chennai sits in the rain shadow of this monsoon, so these months stay hot, with humid evenings and the occasional thunderstorm rather than steady rain. Treat it as a continuation of summer with more damp in the air.
Keep meals light and freshly cooked, since food spoils quickly in this weather. Do not let an evening shower tempt you into a cold-water bath when you are still overheated from the day.
These months are also a useful time to prepare for what follows. If your joints or sinuses reliably suffer in October and November, September is the time to settle your routine and, if you want it, to see the doctor — before the heavy rain rather than in the middle of it.
This is Chennai’s real rainy season, and the classical description of the rains fits it well. Digestion is at its weakest, Vata is provoked by the damp and the sudden cool, and joints and sinuses complain. People with arthritis often notice stiffness before the rain arrives; people with sinus trouble notice it the morning after.
Chennai’s cool months — Margazhi and Thai — are mild by any standard, but the early mornings are cool and dewy and the air is drier. This is the closest the city comes to the classical Hemanta, when digestion is held to be at its strongest.
Classical practice timed purification to the seasons: Vasti during the rains for Vata, Virechana after the rains for Pitta, and Vamana as the cool months end for Kapha. A Panchakarma programme, typically 7 to 21 days, is sometimes scheduled around these junctions for that reason.
That is a principle, not a booking rule. Whether you need purification at all, which procedure and when, is decided at consultation — your health, your medicines and your diary matter as much as the calendar.
Some seasonal illness is not a matter of routine. Any fever during the monsoon months should be seen by a doctor promptly, because dengue, malaria and leptospirosis all occur in Chennai after heavy rain and flooding. In summer, confusion, fainting, a pounding headache or hot, dry skin after time in the heat can be heat stroke — that is an emergency.
For a seasonal plan of your own, Dr.V.Vaitheeshwari B.A.M.S., assesses your constitution through pulse, tongue and history in a first consultation of 40 to 60 minutes, and asks how each season tends to treat you. The hospital is open every day from 10 AM to 8 PM; bring a list of your current medicines.
