Heatwave Safety Tips
What Is a Heatwave?
A heatwave is a prolonged period of excessively hot weather, often combined with high humidity,
that significantly exceeds the normal temperatures for a region. Heatwaves are among the deadliest
natural hazards — they cause more deaths globally than floods, hurricanes, and tornadoes combined.
Rising global temperatures driven by climate change are making heatwaves more frequent, longer-lasting,
and more intense, affecting millions of people each year.
Warning Signs of Heat-Related Illness
- Heat Cramps: Muscle pain or spasms in the abdomen, arms, or legs — usually the first sign of heat illness.
- Heat Exhaustion: Heavy sweating, weakness, cold/pale/clammy skin, weak pulse, nausea, fainting.
- Heat Stroke (Emergency 🚨): Body temperature above 39.4°C (103°F), hot/red/dry skin, rapid pulse, possible unconsciousness. Call emergency services immediately.
- Dehydration: Dark yellow urine, dry mouth, dizziness, and reduced urination are early warning signs.
Before a Heatwave (Prepare)
- Know the location of your nearest cooling center (library, mall, community hall).
- Prepare an emergency kit with bottled water, electrolyte drinks, a battery fan, sunscreen, and a first aid manual.
- Install reflective window coverings or blackout curtains to keep your home cooler.
- Sign up for local weather alerts and heatwave warnings from your national weather service.
- Check on elderly neighbours, young children, and people with chronic illness — they are most at risk.
During a Heatwave (Stay Safe)
- Stay indoors during peak heat (11 AM – 4 PM) and use AC or fans.
- Drink water regularly — don't wait until you feel thirsty.
- Wear loose, lightweight, light-coloured clothing.
- Take cool (not cold) showers to lower your body temperature.
- Never leave children, elderly, or pets in parked vehicles.
- Avoid alcohol and caffeine — they increase dehydration.
- Don't do strenuous outdoor activity during peak heat hours.
- Close curtains on sun-facing windows during the day.
