Following the right heatwave safety tips in Pakistan has never been more urgent than it is in 2026.
As of May 2026, mean temperatures are expected to remain above normal nationwide, which could increase the potential for heat spikes and heatwave conditions, especially over the plain areas of Punjab, Sindh and Balochistan.
Temperatures in Karachi recently climbed to around 42 to 44 degrees Celsius, making it one of the hottest periods seen in recent years. In these conditions, at least eight to ten people died, with reports indicating that most of the deaths were associated with heatstroke and dehydration.
This complete guide covers all the heatwave safety tips you need to protect yourself and your family during Pakistan’s most dangerous summer season in years.
What Is a Heatwave?
Before diving into heatwave safety tips, it is important to understand exactly what a heatwave is and why it is so dangerous.
An extended stretch of scorching weather, often with high humidity, that is much warmer than the average for the area is called a heatwave. It can last from days to weeks and poses serious health risks, including dehydration, heat exhaustion, and heat stroke.
In Pakistan, a heatwave is officially declared when temperatures exceed 45 degrees Celsius for three or more consecutive days. The Pakistan Meteorological Department issues three levels of alerts.
| Alert Level | Temperature Range | Action Required |
|---|---|---|
| Yellow Alert | 40 to 43 degrees Celsius | Stay aware, limit outdoor activity |
| Orange Alert | 43 to 46 degrees Celsius | Avoid outdoor exposure, stay hydrated |
| Red Alert | Above 46 degrees Celsius | Full emergency, stay indoors completely |
Heat extremes can worsen health risks from chronic conditions including cardiovascular, mental, respiratory and diabetes related conditions and cause acute kidney injury, according to the World Health Organisation.
Understanding what a heatwave is makes following heatwave safety tips much more meaningful because you understand the real risks behind each recommendation.
Symptoms of Heat Stroke
Recognizing heat stroke symptoms early is one of the most critical heatwave safety tips anyone can follow.
Understanding the symptoms of heat exhaustion and heat stroke can be life-saving. Heat exhaustion symptoms include headache, nausea, dizziness, weakness, and profuse perspiration. Heat stroke, a more severe condition, can cause a high body temperature, altered mental state, and even unconsciousness.
Heat stroke, also known as sunstroke, is an elevated body temperature that goes up to 104 degrees Fahrenheit or 40 degrees Celsius due to prolonged exposure and overexertion in extreme temperature.
Here is a complete breakdown of symptoms from mild to severe:
| Stage | Symptoms | Action Required |
|---|---|---|
| Heat Cramps | Muscle pain, heavy sweating | Rest, drink water, move to cool area |
| Heat Exhaustion | Dizziness, nausea, weakness, heavy sweating, pale skin | Move to cool area, drink fluids, rest |
| Heat Stroke | Body temperature above 40 degrees, confusion, no sweating, unconsciousness | Call emergency immediately, cool body with water |
Symptoms of heat stroke include dizziness, nausea, and extreme weakness. Patients should immediately be moved to a cool place and given water or home-made drinks.
One of the most important heatwave safety tips to remember is that heat stroke is a life-threatening emergency. If someone stops sweating during extreme heat and becomes confused, call for medical help immediately.
How to Stay Safe in Extreme Heat
The following heatwave safety tips cover everything you need to protect yourself during Pakistan’s dangerous summer months.
Stay Indoors During Peak Hours
People should avoid going out between 11am and 6pm. If necessary, people should carry water bottles and wet cloths for protection.
Avoid direct sun exposure. Whenever possible, remain indoors during the hottest hours of the day, typically between 12 PM and 3 PM.
Dress Appropriately
Wear loose, lightweight, and light-colored clothing. Light colors reflect sunlight rather than absorbing it. Cotton fabric allows the skin to breathe better than synthetic materials. Cover your head with a hat or dupatta when going outside. Never go outside without sun protection during a heatwave.
Keep Your Home Cool
Use curtains or blinds to block out direct sunlight.
Close windows during the day and open them at night when temperatures drop. Use wet sheets or towels hung in front of fans to create a cooling effect. Sleep on the ground floor during extreme heat because heat rises. Place a wet towel on the back of your neck for immediate cooling relief.
Stay Hydrated
Your best defense against heat-related illness is water. Even if you do not feel thirsty, drink water anyway.
Drink at least 10 to 12 glasses of water throughout the day. Do not wait until you feel thirsty because thirst is already a sign of early dehydration. Avoid caffeinated drinks like chai and coffee as they increase dehydration. Avoid alcohol completely during heatwave conditions.
Monitor Weather Updates
Regularly check local weather forecasts for heatwave warnings. Follow local news and social media channels for real-time updates.
These heatwave safety tips for staying safe at home and outdoors are the foundation of surviving extreme heat in Pakistan.

Best Drinks During Heatwave
Knowing what to drink is one of the most practical heatwave safety tips available to Pakistani families.
Lemon water and light meals, especially yogurt, are recommended during heatwave conditions.
Here is a complete guide to the best and worst drinks during a heatwave in Pakistan:
| Drink | Benefit | Recommended Amount |
|---|---|---|
| Plain Water | Best hydration, regulates body temperature | 10 to 12 glasses per day |
| Lemon Water with Salt and Sugar | Replaces lost salts and electrolytes | 2 to 3 glasses per day |
| Lassi (Yogurt Drink) | Cools the body, replaces electrolytes | 1 to 2 glasses per day |
| Coconut Water | Natural electrolytes, very hydrating | 1 to 2 glasses per day |
| ORS (Oral Rehydration Solution) | Medical grade hydration for severe heat | As recommended by doctor |
| Sattu Drink | Traditional cooling drink, high in nutrients | 1 glass per day |
| Fresh Fruit Juice (without sugar) | Vitamins and hydration combined | 1 to 2 glasses per day |
| Aam Panna (Raw Mango Drink) | Traditional summer drink, cools body | 1 glass per day |
Colourful bottled drinks sold in suburban areas often contain bacteria due to heat exposure, leading to diarrhea and cholera.
Following these heatwave safety tips for hydration can prevent the majority of heat-related illnesses that send thousands of Pakistanis to hospitals every summer.
Foods to Avoid in Hot Weather
Diet is an often-overlooked part of heatwave safety tips but it plays a major role in how your body handles extreme temperatures.
Foods to completely avoid during a heatwave in Pakistan:
Fried and Oily Foods generate a lot of internal body heat during digestion. Samosas, pakoras, and heavily fried dishes increase your body temperature and slow digestion during extreme heat.
Spicy Foods increase body temperature and cause excessive sweating which speeds up dehydration. Avoid very spicy curries and dishes during peak heatwave days.
Meat-Heavy Meals take a long time to digest and generate significant body heat. Reduce meat consumption during extreme heat and opt for lighter protein sources.
Salty Snacks like crisps and namkeen increase thirst and cause fluid retention which disrupts the body’s cooling mechanism.
Very Cold Drinks Immediately when extremely hot can cause stomach cramps. Let your body temperature normalize slightly before drinking very cold liquids.
| Foods to Eat | Foods to Avoid |
|---|---|
| Cucumber and watermelon | Deep fried food |
| Yogurt and lassi | Very spicy curries |
| Fresh fruits | Salty snacks |
| Light rice dishes | Heavy meat dishes |
| Mint and coriander | Caffeinated drinks |
| Coconut water | Alcoholic beverages |
These dietary heatwave safety tips are especially important for outdoor workers, students, and anyone who cannot avoid going outside during the hottest part of the day.
Heatwave Safety Tips for Children and Elderly
Children and elderly people are the most vulnerable groups during a heatwave and require specific heatwave safety tips designed for their needs.
The most vulnerable demographics include outdoor laborers, women, kids, and the elderly.
A significant proportion of heatwave victims were between 60 and 70 years old, an age group that is disproportionately vulnerable to the adverse effects of such catastrophic events.
For Children:
Encourage your children to carry a water bottle to school and consume cool drinks throughout the day.
Never leave children alone in a parked car even for a few minutes. A car parked in the sun can reach 70 degrees Celsius inside within minutes.
Dress children in loose, light-colored cotton clothing. Limit outdoor play to early morning before 9am or after sunset. Apply sunscreen with SPF 30 or higher on children going outside. Check on children frequently and look for signs of heat exhaustion including unusual quietness, red face, or stopping play due to fatigue.
School timings during heatwave alerts should ideally be moved to early morning. Parents should communicate with school management if temperatures are dangerously high.
For Elderly:
Check on elderly family members at least twice a day during heatwave conditions. Ensure their room has a working fan or air conditioner.
Elderly people often do not feel thirsty even when dehydrated. Encourage them to drink water every hour regardless of thirst.
People with diabetes, heart conditions, or kidney problems face much higher risk during heatwaves. Make sure their medications are stored at proper temperatures as heat can damage some medicines.
Do not leave elderly people alone in homes without working fans during a heatwave alert.
| Group | Key Risk | Most Important Tip |
|---|---|---|
| Children | Dehydration, overheating | Water every hour, avoid midday sun |
| Elderly | Silent dehydration, heart stress | Scheduled water intake, check frequently |
| Outdoor Workers | Prolonged heat exposure | Wet cloth on neck, frequent breaks in shade |
| Pregnant Women | Overheating, premature labor | Stay cool, drink more water than usual |
| Chronic Illness Patients | Medication and heat interaction | Consult doctor, store medications properly |
Karachi Heatwave Situation 2026
Karachi is facing some of its most severe heatwave conditions in recent years in 2026 and these heatwave safety tips are particularly urgent for Karachi residents.
An intense spell of heat in Karachi has put growing pressure on the city’s healthcare system, with government and private hospitals reporting a steady influx of patients affected by heat-related illnesses. According to the report, temperatures in Karachi recently climbed to around 42 to 44 degrees Celsius, making it one of the hottest periods seen in recent years.
At Jinnah Hospital, 80 to 90 patients are reporting daily for treatment. Similar conditions have been reported at Abbasi Shaheed Hospital, Sindh Government Qatar Hospital, Liaquatabad Hospital, Malir Saudabad Hospital and Korangi Hospital, where dozens of patients are arriving each day.
Karachi alone reports around 1,500 cases of heat stroke and several deaths every day as a result of the sharp temperature rise, and 30 to 40 people are taken to the Karachi city mortuary daily, according to the Edhi ambulance service.
The situation is made worse by two specific Karachi problems.
The long 12 plus hour power cuts all over the city worsen the situation as studies show that power cuts make heat waves even deadlier.
Karachi, being the most populous and polluted city in Pakistan, makes a worldwide contribution to making global warming even worse. Due to continuous vehicular and industrial emissions, deforestation, and excessive fuel and petrol consumption, the city has become more susceptible to such vulnerable events as heat stroke and global warming.
Specific heatwave safety tips for Karachi residents in 2026 include registering with your nearest cooling center location which the Sindh government has set up across the city, keeping a battery-powered or rechargeable fan ready for power cut hours, storing extra water at home since water supply becomes unreliable during peak heatwave days, and knowing the location of the nearest government hospital with a heat stroke emergency unit.
When to See a Doctor
Knowing when to seek medical help is one of the most critical heatwave safety tips of all.
Go to the hospital immediately or call for an ambulance if you or anyone around you experiences any of these symptoms:
Body temperature above 40 degrees Celsius or 104 degrees Fahrenheit that does not come down with cooling measures. Stopping sweating despite extreme heat which indicates the body’s cooling system has shut down. Confusion, disorientation, or loss of consciousness. Rapid heartbeat combined with weakness or chest pain. Seizures or convulsions. Vomiting that makes it impossible to keep liquids down. No urination for 8 hours or more which indicates severe dehydration.
If you or someone else shows signs of heat stroke, seek medical attention immediately.
While waiting for help or transport to the hospital, apply these emergency heatwave safety tips:
Move the person to the coolest available place immediately. Remove excess clothing. Apply cool water or wet cloths to the neck, armpits, and groin area. Fan the person continuously to speed up evaporative cooling. Give water by mouth only if the person is fully conscious and able to swallow. Do not give anything by mouth to someone who is confused or unconscious.
Here is a quick reference guide for emergency response:
| Situation | Immediate Action | Medical Need |
|---|---|---|
| Heavy sweating, dizziness | Move to shade, give water | Monitor, may not need hospital |
| Stops sweating, confusion | Cool with water, fan immediately | Emergency, call hospital |
| Unconscious | Cool body, call ambulance | Critical emergency |
| Seizures | Keep safe, do not restrain | Critical emergency |
| High fever above 40 degrees | Cold wet cloths, fan | Go to hospital immediately |
Government hospitals in Karachi that have dedicated heat stroke emergency units include Civil Hospital Karachi, Jinnah Hospital, Abbasi Shaheed Hospital, and Sindh Government Qatar Hospital.
