Heatwave and Load Shedding: How to Cool Down Without a Fan
Two in the afternoon, forty-four degrees, and load shedding has taken the power for three hours with two more to go. This is the version of summer that most advice ignores, because most advice assumes a fan. Here is what actually helps when the electricity is the thing you cannot count on.
Before you start
- Cool the person, not the house. A wet cloth on skin beats an hour of trying to chill a room.
- The one rule: wet skin plus moving air. Either alone is half the effect.
- Drink on a clock, not when thirsty. Thirst lags behind losses.
- Stop everything if: confusion, fainting, vomiting, or skin gone very hot, whether it is dry or still sweating. That is an emergency, not a rest.

Cooling a room during load shedding
Most heat that makes an afternoon unbearable came in through a window earlier in the day and is now sitting in your walls and floor. So the work happens before the heat. Not during it.
Shut windows and draw curtains by about nine in the morning on the sunny side of the house. A wet chaadar or old sheet hung inside a sunny window does two jobs, blocking light and cooling slightly as the water evaporates, so long as some air moves past it. Rewet it every hour or so. If you have a khas or vetiver screen, this is what it was invented for.
Then open up hard once the sun is off the walls, usually after sunset, and get air crossing the house: one window open low on the cooler side, another open high on the opposite side. Heat leaves upward. A single open window is a hole, not a draught.
Floors are your friend. Sleeping low, on a chatai or a thin mattress on a damp-mopped floor, is cooler than a bed, and move to the roof once the surfaces up there stop radiating, which is later than people think.
Swap this for that
| Stop | Start | Why |
|---|---|---|
| Waiting out the load shedding indoors on a bed | A damp-mopped floor, lowest room in the house, curtains shut | Hot air rises and bedding traps your own heat against you. |
| Ice-cold shower to cool down | Tepid to cool shower, then air dry without towelling off | Very cold water can make you shiver and clamp down blood flow to the skin. The evaporation afterwards does the real cooling. |
| Drinking only when thirsty | A glass every hour, more if sweating | You are already behind by the time thirst arrives, especially for older people. |
| Heavy oiled lunch at peak heat | Lighter meals, fruit, dahi, the main meal moved to evening | Easier on a body already working hard, and it keeps you off the stove at the worst hour. |
| Synthetic nightclothes | Loose, thin cotton, or a damp cotton kurta | Sweat that cannot evaporate is sweat that is not cooling you. |
| Candles during a cut | A charged torch or a rechargeable lamp | Candles add heat, and every hot season brings house fires from one knocked over near a mosquito net. |
Cooling your body, safely
This is the part that works within minutes. It costs nothing but a mug of water.
- Wet a thin cotton cloth in plain tap water, around 250 ml is plenty, and wring it out so it is damp rather than dripping.
- Lay it over the pulse points: back of the neck, the wrists, the inside of the elbows, and behind the knees. Blood runs close to the surface there, so it is the most efficient placement.
- Get air moving across it. A hand fan, a folded newspaper, anything. 2 minutes of fanning does more than 10 minutes of a wet cloth sitting still.
- Rewet every 10 to 15 minutes as the cloth warms to skin temperature. A warm cloth left in place is a blanket.
- Feet in water. A bucket with 4 to 5 litres of cool, not iced, water, feet in for 10 to 15 minutes. Cheap, effective, and something an older relative can do sitting in a chair.
- Mist and let it dry. A spray bottle of plain water on the arms, face and neck, left to evaporate rather than wiped off. Rose water in the bottle is pleasant. It does nothing extra, which is fine.
Two notes on ice. Iced water straight from the freezer against the skin of a frail elderly person or a small child is unnecessarily harsh. Shivering generates heat. Cool is enough. And never use ice, or cold anything, as a reason to delay getting help for someone who is genuinely unwell in the heat.
The same trick makes a hot night survivable. Go to bed already cool and slightly damp: a tepid shower just before lying down, no towel, a thin damp cotton sheet over you rather than under. As the water evaporates you get a window of comfort, usually long enough to fall asleep, which is the hard part.
Drinking, and what to put in the water
Sweat is water and salt. Replacing only the water, in large amounts, on a day of heavy sweating is how some people end up feeling worse. Ordinary meals cover most of the salt. That is why the old pairing of water with a properly salted meal is sensible.
A plain jug of water with a pinch of salt and a squeeze of lemon over the afternoon is an easy habit. For actual fluid losses, vomiting or loose motions in this weather, use a correctly mixed oral rehydration solution rather than guesswork, and the namak cheeni ghol recipe and its exact proportions matter, because a badly mixed one is worse than none. Lassi, sattu, coconut water and plain nimbu pani all count as fluids, and coconut water has its own kidney caveat if you have been told to watch potassium.
Skip alcohol, go easy on very sugary bottled drinks, and do not push tea as your main fluid on a brutal day. If a doctor has restricted your fluid or salt intake for heart or kidney reasons, ask them specifically how to handle a heatwave rather than following general advice, because general advice can be the wrong advice for you.
Heatstroke: the signs that mean stop everything
Heat exhaustion is miserable and recoverable at home. Heatstroke is a medical emergency and people die of it every summer on the plains, often older people alone in a room during a long cut.
Move toward help, not toward another glass of water, if you see confusion, strange behaviour, slurred speech, unsteadiness or collapse, a seizure, vomiting that will not stop, a body that has gone very hot whether the skin is dry or still pouring sweat, because heatstroke happens both ways, or someone who cannot be roused properly. Get them into shade or the coolest room, strip off extra clothing, wet the skin and fan hard, put cool packs at the neck, armpits and groin, and call for medical help while you do it. Do not try to pour fluids into someone who is drowsy or not fully alert. Loo lagna, and how heat exhaustion differs from heatstroke, is worth reading before the season rather than during it.
Highest risk: babies and small children, anyone over about sixty five, pregnancy, people with heart, kidney or lung conditions, anyone on regular medicines including some for blood pressure, outdoor workers, and anyone who lives alone. Check on that last group daily during a heatwave.
And the one that needs no qualification: never leave a child or an older person in a parked car, not for two minutes, not with the window cracked.
Unani writing classes summer as hot and dry and prescribes the opposite qualities, cooling foods and drinks, rest through the worst hours, cool baths. Ayurveda’s ritucharya says much the same for grishma, the peak heat: light meals, midday rest, cool water, avoiding exertion in the sun. The khas screen, the floor wiped with water, sattu and lassi in the afternoon, the charpai on the roof after dark, all of it predates electricity and none of it stops working when the electricity does. Read it as sensible custom rather than medicine.
Makeshift cooling and the electrical risk
Every hot season, improvised cooling hurts somebody. A few things need saying bluntly.
Never run a petrol or diesel generator inside the house, in a closed verandah, in a garage, or next to an open window. Carbon monoxide has no smell and it kills people while they sleep. Outdoors, well away from windows, always.
Do not drape wet cloths over fans, coolers, wiring or any appliance, and do not balance a bowl of ice on top of an electrical unit. Keep wet hands off switches, plugs and inverter terminals, and keep the floor around a room cooler dry, because a puddle plus a socket is the classic combination. Inverter and UPS batteries need ventilation and should not live in a sealed bedroom.
Watch the load when power returns: everything switching on at once, on old wiring, is how fires start. Keep candles away from mosquito nets and bedding, or better, skip them.
Call for medical help for confusion, fainting, a seizure, skin that is very hot whether dry or sweating, repeated vomiting, or any child who is floppy, unusually sleepy, has sunken eyes, or has not passed urine for many hours. Older people can be seriously unwell in heat with very few complaints, so judge by how they are behaving rather than what they say. If you are pregnant, or you have heart, kidney or lung disease, or you take regular medication, ask your own doctor before the hot months how to adjust fluids and activity, because standard heatwave advice is not always right for you.
Do this before the next cut
Fill two bottles and freeze them overnight while the power is on, and keep a thin cotton cloth and a hand fan next to where you sit out the afternoon. When the lights go, you have cold water that keeps for hours and the only cooling method that works without a socket.
Where this sits in the year
Peak heat has a whole routine of its own around sun, sweat and chafing, and this piece deliberately skips that ground; start with the peak summer routine and use this one for the days the power goes. If the heat lands during a fasting month, the fluid rules change completely and the Ramadan care routine covers that. The rest of the year, season by season, sits on the Season Shift hub.
Does a wet sheet over the window actually cool a room?
A little, as long as some air is moving past it, because evaporation takes heat with it. In humid weather it works much less well and can make the room feel closer. The bigger win is simply blocking the sun before the room heats up.
Is it safe to sleep in a wet kurta?
For most healthy adults in dry heat, yes, and it is a very old habit. Keep it damp rather than soaked, use cotton, and skip it for infants, frail elderly people, or anyone who starts shivering, and if you wake up cold and clammy, it was too wet.
How much water should I actually drink?
There is no single number that fits everyone, and anyone quoting one is guessing about you. Use your urine as the guide: pale straw, and passing it regularly through the day. Dark yellow and infrequent means drink more, unless a doctor has restricted your fluids.
Someone fainted in the heat. What do I do first?
Get them flat in the coolest shaded place you can reach, raise the legs, loosen clothing, and start cooling the skin with water and air movement. Call for medical help straight away if they do not come round quickly, seem confused, or feel very hot to the touch. Do not give drinks to anyone who is not fully alert.
