How to Reduce Body Heat (Garmi) in Summer: What Works, What Doesn’t
“Garmi ho gayi hai.” It’s said about a nosebleed, a mouth ulcer, burning soles at night, a crop of boils, a short temper, a bad stomach and a fever, and the pharmacist nods and hands over a sachet. Reducing body heat in summer starts with unpacking what people mean by it, because half of “garmi” is dehydration you can fix by evening, and a small part is something a doctor needs to see.
In brief
- What “garmi” usually is: not enough water, too much sun, too little sleep, heavy spiced food in heat, and sweat rash.
- Fix first: fluids by the clock, shade between 11 and 4, loose cotton, a cooled room before sleep.
- Cooling foods: a real tradition, useful as a way to get water and salt in; not a medicine.
- Emergency: confusion, very hot skin (dry or still sweating), fainting, no sweat in a hot person. Cool them and call for help.
- Not garmi: yellow eyes, burning urine, a fever over 3 days, ulcers that last past 2 weeks.

What people mean when they say “body heat”
There’s no thermometer reading for garmi. It’s a folk word for a cluster of summer complaints, and the cluster is worth separating because each piece has a different fix. Burning palms and soles at night, a dry mouth, headache and dark urine: that’s a person who drank a litre and sweated three. Boils, prickly heat and an itchy back: sweat glands blocked under damp clothes, covered in prickly heat home remedies. A summer nosebleed: air-conditioned dry air cracking the lining of the nose, or a lot of sun. Mouth ulcers: often stress, poor sleep and a bitten cheek, and they cluster in exam season for reasons that have nothing to do with the weather. Short temper and poor sleep: a bedroom at 34 °C. Each one is real. None of them is a mysterious internal fire.
There’s a specific variant, jigar ki garmi, “heat of the liver”, used for a set of symptoms from bitter taste and nausea to acne and low mood. The liver is not hotter than the rest of you. If the symptoms come with yellowing eyes, dark tea-coloured urine, pale stools or a tender right upper belly, that’s a liver question for a doctor and a blood test, not for a sharbat.
The Unani and Ayurvedic idea, and where it’s useful
In Unani medicine a person’s mizaj, or temperament, sits somewhere between hot and cold, wet and dry, and summer is read as a hot dry season that pushes the body’s own heat upward; the remedy is food and drink of the opposite quality. Falsa, kheera, tarbooz, sattu, gond katira, tukh malanga (basil seed), khus and sandal sharbats, dahi and chaas are all “thanda” in that reckoning. Ayurveda’s grishma ritucharya says much the same: pitta rises in hot months, so eat sweet, cool, liquid foods, avoid sour, salty, pungent and hot things, rest in the afternoon, and sleep in a breezy room. Whether or not you accept the framework, look at the list: it’s water-rich food, less chilli, less frying, more rest and better airflow. As practical summer advice it’s hard to fault.
Where the tradition misleads is when the label replaces the diagnosis. A “cooling” sachet won’t do anything for a urine infection, a liver problem or an untreated fever, and calling them garmi delays the visit that would settle them.
Hydration, done by the clock
Most “garmi” resolves with fluid taken steadily rather than gulped when thirsty, because by the time you’re thirsty in a Pakistani June you’re already behind. The detail of how much is in how much water to drink in Pakistani heat; the short version is 2.5 to 3.5 litres a day for an adult who’s mostly indoors, more with outdoor work, judged by urine that stays pale yellow.
- On waking: 500 ml of water before chai. The night’s sweat has to be paid back before the caffeine takes its share.
- Through the morning: a 250 ml glass every hour. Keep the bottle where you sit; a bottle in another room is a bottle you won’t drink from.
- Midday: a glass of something with a little salt and sugar: thin chaas with a pinch of salt, a lightly salted nimbu pani, salty sattu sharbat, or half-strength ORS if you’ve been sweating hard. Plain water alone, in litres, without any salt on a heavy-sweat day, leaves you weak and headachy.
- Afternoon: a water-rich snack counts. 200 g of tarbooz or kheera is about 180 ml of water with the potassium thrown in.
- Evening: ease off an hour before bed so you’re not up three times, but go to bed hydrated. A last glass at dinner, not at midnight.
- Check: urine pale, headache gone, palms no longer burning by bedtime. If not, tomorrow’s numbers go up.
Cooling foods, described as what they are
The summer table in a desi home is already built for heat, and it deserves credit for that. Tarbooz, kharbooza, kheera, falsa, sugarcane, lauki and tori curries, dahi and chaas, sattu, gond katira, tukh malanga soaked into a drink, khus and rose sharbats, kachi lassi, and a raw onion with the meal. Every one of them is a way of taking in water, and several bring salt or potassium with it. That’s the mechanism, and it’s a good one. What they are not is medicine that lowers a temperature: a person with a fever needs paracetamol and a doctor’s eye if it lasts, not a plate of melon. And most of the sharbats carry sugar by the spoonful, so a “cooling” habit of four glasses of Rooh Afza a day is a sugar habit with a cool name; make falsa sharbat and gond katira at home where you control the sugar, and lean on chaas, kheera and water for the bulk of it. Salty sour drinks like jaljeera are for meals, not for all-day sipping, because their cooling is mostly salt. The raw onion tradition is its own story, told honestly in raw onion and the loo myths.
The other half of the traditional advice is what to eat less of, and here the tradition is simply right. Chilli-heavy, deep-fried, heavy meat dishes at 2 p.m. in June add a little to the body’s own heat production and sit in the stomach when blood is being sent to the skin to cool you. Move the karahi to after sundown and eat daal-chawal, dahi and sabzi in the day.
Clothing, sleep and the room
Loose, pale, cotton or lawn. A tight polyester kameez traps sweat against the skin, which is where prickly heat and boils start; a loose lawn kurta lets sweat evaporate, which is the body’s only real cooling system. Change out of sweaty clothes rather than letting them dry on you. Wear a cap or dupatta over the head in direct sun, and stay in shade between 11 a.m. and 4 p.m. wherever the day allows it.
Sleep is where summer heat does its quiet damage, and a week of broken sleep produces exactly the irritability, ulcers and headaches that get called garmi. Cool the room before you get into it: windows open at both ends after sunset for a cross-breeze, curtains closed against the afternoon sun, a bucket of water in front of the fan in dry heat, a cotton sheet and nothing heavier. A lukewarm shower before bed (not cold; cold makes the body work to warm back up) brings the skin temperature down for an hour. When there’s no power, the tricks in cooling without a fan in load shedding hold. Sweat and smell have their own page in summer heat, sweat and cooling.
The three-day garmi test
Before buying a sachet, run three days of the hydration plan above, move dinner’s chilli and oil to after dark, cut screens after 10 p.m., and sleep in a room you’ve cooled first. If the burning soles, headache, dry mouth and bad mood are gone by day three, it was heat and water, and now you know. If a specific symptom is still there, it isn’t garmi and it’s on the list below.
When “garmi” needs a doctor
Emergency, now: someone in from the heat who is confused, agitated, slurring or fainting, with very hot skin whether dry or still sweating, or who has stopped sweating in the heat, or who has a fever above 40 °C. Move them to shade, strip outer layers, soak the skin with cool water and fan them, cold packs at neck, armpits and groin, and call for help; don’t give fluids to anyone who’s confused or drowsy. The full first-aid sequence is in the heatstroke first-aid article. Earlier than that, heat exhaustion looks like heavy sweating, cramps, nausea, headache and dizziness; rest, cooling and ORS should turn it round within an hour, and if it doesn’t, that’s a doctor. Same day: burning or frequent urination (a urine infection, not garmi); yellow eyes, dark tea-coloured urine or pale stools (liver, not garmi); a fever past 3 days or any fever with rash, stiff neck or breathlessness; a nosebleed that won’t stop in 20 minutes of pinching or that keeps recurring; mouth ulcers lasting more than 2 weeks or a single ulcer that grows. Extra care in the heat for babies and the elderly, who don’t feel thirst reliably; for pregnant women, in whom dizziness and swelling need mentioning at the next visit; for anyone with diabetes, whose readings go unpredictable when dehydrated; for kidney or heart patients on a fluid limit or on diuretics, who should not follow a 3-litre plan without asking their doctor; and for anyone on blood pressure tablets, antidepressants, antihistamines or antipsychotics, some of which reduce sweating or blunt thirst. Never stop or change any of those because it’s hot; ask the prescriber what to do in a heatwave.

Garmi questions, answered
How do I reduce body heat immediately?
Get into shade or a cooled room, sip 500 ml of water or half-strength ORS, wet the face, neck and wrists with cool water, and sit under a fan in loose clothes. Burning palms and a dehydration headache usually ease within the hour. Someone who is confused or very hot to touch is an emergency, not a home-remedy case.
What are the symptoms of garmi in the body?
People use garmi for a cluster of summer complaints: burning palms and soles, dry mouth, headache, dark urine, prickly heat, boils, irritability and poor sleep. Most of it is fluid loss plus a hot bedroom. Each symptom has its own fix, and anything that lingers past a few days of good hydration probably isn’t heat at all.
What foods reduce body heat in summer?
Water-rich ones: tarbooz, kharbooza, kheera, lauki, tori, falsa, dahi, chaas and sattu. Tradition calls them thanda; the practical reason they help is the water, with some salt or potassium alongside. Eating less chilli and fried food at midday matters just as much as adding any single food.
How much water should I drink to get rid of garmi?
Most adults who are mostly indoors need about 2.5 to 3.5 litres a day in a Pakistani summer, more with outdoor work. Spread it through the day, starting with 500 ml on waking, and judge it by urine that stays pale yellow. Kidney or heart patients on a fluid limit should ask their doctor first.
Why do my palms and feet burn at night in summer?
Usually it’s too little fluid and a hot room. Fix both for a week first. If the burning carries on after that, or comes with numbness, tingling or pins and needles, it may be a nerve problem, low vitamin B12 or diabetes, and a doctor and a blood test are the next step.
Do cooling sachets and Rooh Afza actually work?
They help only because you’re drinking water with some sugar and salt in it. Most are sugar-heavy, so four glasses a day becomes a sugar habit. Homemade falsa sharbat or gond katira with less sugar, chaas, or water with a pinch of salt on a sweaty day do the same job.
Is gond katira good for body heat?
It’s a traditional summer drink, and soaked in water with a little lemon it’s a pleasant way to get fluid in. The tradition calls it cooling; think of it as a drink, not a medicine. Soak it properly (it swells a lot) and keep the added sugar low.
Can garmi cause fever?
Heatstroke can push temperature above 40 °C, and that’s an emergency. An ordinary fever with chills, cough, sore throat or body ache is an infection, not garmi. A fever lasting past 3 days, or any fever with rash, stiff neck or breathlessness, needs a doctor that day.
Is jigar ki garmi a real thing?
It’s a traditional label, not a diagnosis, and the liver isn’t hotter than the rest of you. Bitter taste, nausea or acne have ordinary causes. Yellow eyes, tea-coloured urine, pale stools or pain under the right ribs point to the liver, and that needs a doctor and a blood test, not a sharbat.
What are the warning signs of heatstroke?
Confusion, slurred speech, fainting or agitation in someone with very hot skin, whether it’s dry or still sweating. Cool them straight away: shade, outer clothes off, soak the skin and fan, cold packs at the neck, armpits and groin, and call for help. Don’t give drinks to anyone drowsy or confused.
Can garmi cause nosebleeds and mouth ulcers?
Not directly. Summer nosebleeds usually come from dry air-conditioned air or a lot of sun cracking the nasal lining, and ulcers from stress, poor sleep or a bitten cheek. A nosebleed that won’t stop after 20 minutes of pinching, or an ulcer lasting over 2 weeks, needs checking.
Should I take a cold shower before bed to cool down?
A lukewarm one works better. Very cold water makes the body work to warm itself back up, while lukewarm water brings skin temperature down for about an hour. Pair it with a room cooled by cross-ventilation after sunset and a thin cotton sheet.
Can I take my BP tablets as usual in a heatwave?
Don’t stop or change them on your own. Some BP tablets, water pills, antidepressants and antihistamines affect sweating or thirst, so ask your prescriber what to watch for in the heat. Diabetics should check readings more often, as dehydration can make sugar unpredictable.
How do I keep babies and elderly parents cool in summer?
Offer fluids on a schedule, because neither group feels thirst reliably. Babies under 6 months need only more breastfeeds or formula, never plain water. Keep them in shade, in loose cotton, in a ventilated room, and treat drowsiness, few wet nappies or confusion as a reason to see a doctor quickly.
