Loo Lagna: Heat Exhaustion vs Heatstroke First Aid at Home
Heatstroke is a medical emergency, and it can kill within hours. Everything else in this article about loo lagna, the kachi keri panna, the wet cloths, the shade, comes second to recognising that one moment when home care stops and a hospital takes over.

The person is confused, slurring, agitated, behaving strangely or not making sense; faints or can’t be woken properly; has a seizure; has very hot skin (with or without sweating); has a body temperature of around 40°C or higher; is vomiting repeatedly and can’t keep fluids down; or doesn’t improve within 30 minutes of cooling and rest. Start cooling immediately while waiting for help. Don’t give anything to drink to someone who is confused or drowsy, as they may choke. Babies, young children, older people, pregnant women, people with heart, kidney or lung problems, diabetes, and people taking water tablets (diuretics), some BP medicines or some psychiatric medicines are at higher risk and should be taken to a doctor sooner. Don’t give paracetamol or aspirin for heatstroke; they don’t bring down heat-caused temperature and can cause harm.
Heat exhaustion vs heatstroke
People use “loo lag gayi” for everything from a bad afternoon headache to a collapse in the fields. Medically, there’s a spectrum. Heat exhaustion is the body struggling but still coping. Heatstroke is the body’s cooling system failing. One can turn into the other quickly.
| Sign | Heat exhaustion | Heatstroke |
|---|---|---|
| Mind | Clear, tired, irritable | Confused, odd, drowsy |
| Skin | Sweaty, pale, clammy | Very hot; may be dry |
| Other | Headache, nausea, cramps, thirst, dizziness | Seizure, fainting, collapse |
| Response | Improves within 30 min of cooling | Emergency, call help |
Loo lagna first aid: cool first, then fluids
- Move them out of the heat. Into shade, an air-conditioned room, or the coolest room in the house under a fan.
- Lie them down and raise their legs slightly on a pillow if they feel faint.
- Remove extra clothing. Take off the jacket, shoes, socks and tight clothes. Loosen the shalwar string or belt.
- Wet the skin. Spray or sponge cool tap water all over the body, or cover them with a wet thin cotton sheet or dupatta.
- Fan them hard. The moving air over wet skin is what pulls heat out. A pedestal fan, a hand fan, a newspaper, anything.
- If you can, sit or lay someone with suspected heatstroke in a bathtub or large tub of cool water up to the neck, supported and never left alone; it is the fastest way to cool them. Otherwise keep wetting and fanning.
- Cold packs. Wrap ice packs or bags of ice in cloth and put them in the armpits, groin, and on the neck. Change them as they warm.
- If fully alert, give small sips of cool water or homemade ORS, about 100 to 200 ml over 10 to 15 minutes, then keep sipping. Don’t let them gulp a litre at once.
- Watch for 30 minutes. If they aren’t clearly getting better, or they get worse, go to hospital.
With suspected heatstroke, keep cooling during the whole trip to hospital. Wet cloths and open windows in the car or rickshaw. Cooling starts saving lives before a doctor arrives.
Heat cramps, painful spasms in the calves or stomach after hard work or sport in the heat, are a milder cousin. Stop, rest in shade, stretch the muscle gently and sip ORS or salted chaas. If cramps last more than an hour, or come with the heat exhaustion signs above, treat it as heat exhaustion.
What to drink in loo season
For someone recovering from heat exhaustion, and for everyone during a heatwave, a steady flow of fluids through the day matters more than a big glass at night. Good household options:
- Water, cool, sipped often.
- Homemade ORS if there’s been lots of sweating, vomiting or loose motions.
- Salted chaas with a pinch of roasted jeera.
- Sattu sharbat, the salty version.
- Kachi keri ka panna, lightly sweetened.
Kachi keri panna for loo season
- Boil or pressure cook 2 medium raw green mangoes (about 400 g) in water until soft, about 15 minutes boiling or 2 whistles.
- Cool, peel, and squeeze out all the pulp. Discard the stone and skin.
- Blend the pulp with 4 tablespoons (about 50 g) of sugar or gur, 1 teaspoon roasted jeera powder, half a teaspoon kala namak and a quarter teaspoon regular salt.
- This makes about 1 cup of concentrate. Store covered in the fridge for up to 3 days.
- For one glass, mix 2 tablespoons of concentrate into 250 ml of cool water and add a few mint leaves.
People with diabetes should use far less sugar or skip panna and stick to chaas and water. Avoid alcohol, and cut back on very sweet cold drinks and lots of strong tea or coffee in a heatwave.
Across Punjab, Sindh, Rajasthan and UP, families had a clear loo routine: a raw onion carried in the pocket, kachi keri panna, sattu, bel sharbat, a wet cloth on the head, and no stepping out between noon and late afternoon. Unani tradition sees loo as an assault of external heat and dryness, and prescribes cooling, moistening drinks and rest in shade. Ayurveda’s ritucharya (seasonal routine) for grishma, the hot season, advises sweet, cooling, liquid foods and avoiding hard exertion at midday. The onion in the pocket is folklore with no known effect. The rest, shade, rest, cooling drinks, is sound.
The day after heat exhaustion
Someone who had a bad bout of heat exhaustion often feels washed out for a day or two. That’s normal. Keep them resting indoors in the coolest room, offer fluids every hour they’re awake, and give light meals: dahi chawal, khichdi, fruit. No outdoor work, cricket or long bazaar trips in the afternoon for at least a day or two.
Watch the urine. Dark, scanty urine means they’re still behind on fluids. Staying ahead of that in the first place is what our week of hot weather hydration is for. And keep an eye on the mind: new confusion, unusual drowsiness or a fresh fever the next day is a reason to see a doctor, not to wait.
Preventing heat illness in peak summer
- Plan outdoor work, errands and play for early morning or after sunset.
- Wear loose, light-coloured cotton, and a cap, hat or a wet scarf on the head.
- Carry water every time you leave the house. Drink before you feel thirsty.
- Never leave a child, an elderly person or a pet in a parked car, even for “two minutes”.
- Check on elderly neighbours and relatives who live alone during a heatwave.
- Take cool showers or wash face, hands and feet several times a day.
- Eat lighter: dahi, fruit, cucumbers, lauki, simple dal and rice rather than heavy fried meals.

What people ask about loo lagna
What are the symptoms of loo lagna?
Heat exhaustion brings heavy sweating, pale clammy skin, headache, nausea, dizziness, muscle cramps and strong thirst, while the mind stays clear. Heatstroke is more serious: confusion, odd behaviour, drowsiness, fainting or a seizure, with very hot skin that may be dry or still sweating.
How do I know if it’s heatstroke or just tiredness?
Watch the mind. Confusion, strange behaviour, slurred speech, drowsiness, fainting or a seizure in the heat means heatstroke until proved otherwise. Call for help and start cooling at once. Someone tired but thinking clearly, who improves within 30 minutes of cooling, is more likely to have heat exhaustion.
What is the first aid for loo lagna at home?
Move the person into shade or the coolest room, loosen or remove extra clothing, wet the skin with cool water and fan hard. Put wrapped ice packs in the armpits, groin and on the neck. If they’re fully alert, give small sips of cool water or ORS, then watch closely for 30 minutes.
Can I give paracetamol for loo?
Not for heatstroke. Paracetamol and aspirin don’t bring down a temperature caused by heat, and they can do harm. Cooling is the treatment. For a mild heat headache in someone who’s clearly alert, ask a pharmacist.
Is it safe to use ice water on someone with heatstroke?
Yes, fast cooling is the priority. A tub of cool water up to the neck, with the person supported and never left alone, is the quickest method. Wet sheets, hard fanning and ice packs in the armpits and groin all work too. Stop once they’re alert and comfortable, and let the hospital take over.
What should I drink to prevent loo in summer?
Sip water steadily through the day rather than gulping a big glass at night. Salted chaas with roasted jeera, salty sattu sharbat, lightly sweetened kachi keri panna and homemade ORS after heavy sweating all help. Cut back on alcohol, very sweet cold drinks and lots of strong tea.
How do I make ORS at home for heat exhaustion?
Mix 6 level teaspoons of sugar and half a level teaspoon of salt into 1 litre of clean, boiled and cooled water, stirring until dissolved. Give it in small sips, about 100 to 200 ml over 10 to 15 minutes, and only to someone fully alert.
Is kachi keri panna good for loo?
It’s a traditional summer drink and a good way to get fluid and a little salt into people who won’t drink plain water. It isn’t a treatment for heatstroke, though. People with diabetes should make it with far less sugar or stick to chaas and water.
Can I give water to someone who has fainted from the heat?
Not while they’re confused, drowsy or not fully awake, as they may choke. Focus on cooling and call for help. Once they’re completely alert and can hold a cup themselves, small sips of cool water or ORS are fine.
What should a baby drink in a heatwave?
Babies under 6 months should keep breastfeeding or formula feeding, just more often; don’t give plain water unless a doctor advises it. A hot, floppy or unusually sleepy baby, or one with fewer wet nappies, needs a doctor straight away.
I’m pregnant. How careful should I be in the heat?
Very careful. Rest in the coolest place you can, drink steadily through the day and avoid the midday sun. See your doctor promptly for dizziness, vomiting, a headache that won’t settle, or fewer baby movements than usual.
Who is most at risk of heatstroke?
Babies and young children, older people, pregnant women, and anyone with heart, kidney or lung disease or diabetes. People taking water tablets, some BP medicines or some psychiatric medicines are also at higher risk, so they should see a doctor sooner if they feel unwell in the heat.
How long does it take to recover from heat exhaustion?
Most people feel washed out for a day or two. Keep them resting indoors in a cool room, offer fluids every hour and give light food like dahi chawal or khichdi. Dark, scanty urine means they’re still short of fluids. New confusion or fever the next day needs a doctor.
What are heat cramps and what should I do?
They’re painful spasms in the calves or stomach after hard work or sport in the heat, a milder cousin of heat exhaustion. Stop, rest in the shade, gently stretch the muscle and sip ORS or salted chaas. If cramps last more than an hour, or come with dizziness, nausea or heavy sweating, treat it as heat exhaustion.
Does carrying an onion prevent loo?
No, it’s folklore with no known effect. What protects you is shade, steady fluids, loose light cotton clothes, a covered head and keeping out of the sun between noon and late afternoon.
Is it safe to leave a child in a parked car for a few minutes?
Never, not even for two minutes. A closed car heats up very fast in summer, and children, older people and pets can develop heatstroke quickly. Take them with you every time.
