Understanding a Heatwave
Before diving into safety instructions, it’s important to understand what a heatwave is and why it matters.
What Is a Heatwave?
A heatwave is a prolonged period of excessively hot weather, often combined with high humidity, that can last for several days or even weeks. The specific temperature thresholds that define a heatwave vary by region, but generally, they involve temperatures significantly higher than the average for a particular area.
Why Are Heatwaves Dangerous?
- Health Risks: Heat exhaustion, heatstroke, dehydration, and worsening of existing health conditions.
- Environmental Impact: Increased risk of wildfires, droughts, and damage to crops.
- Infrastructure Stress: Power outages due to high electricity demand for cooling.

During a Heatwave: Safety Instructions
When a heatwave hits, following these safety instructions can help protect your health and well-being.
Stay Hydrated
- Drink plenty of water regularly, even if you don’t feel thirsty.
- Avoid alcohol, caffeine, and sugary drinks, as they can cause dehydration.
- Use electrolyte-replenishing drinks if experiencing excessive sweating.
Keep Cool
- Stay indoors during the hottest parts of the day, typically between 10 a.m. and 4 p.m.
- Use fans or air conditioning whenever possible.
- Take cool showers or baths to lower your body temperature.
- Wear lightweight, loose-fitting, and light-colored clothing.
Limit Physical Activity
- Avoid strenuous exercise during peak heat hours.
- If physical activity is necessary, do so early in the morning or late in the evening when it’s cooler.
- Rest frequently and seek shade if outdoors.
Protect Vulnerable Populations
- Check on elderly family members, neighbors, and individuals with chronic illnesses regularly.
- Ensure they have access to cool environments, hydration, and medications.
- Assist with transportation to cooling centers if needed.
Manage Your Environment
- Close blinds, curtains, or shades during the day to block out heat.
- Create cross-ventilation by opening windows on opposite sides of your home during cooler parts of the day.
- Use fans to circulate air, but be aware that fans are less effective if the indoor temperature exceeds body temperature.
Recognize Signs of Heat-Related Illnesses
- Heat exhaustion: heavy sweating, weakness, dizziness, nausea, headache.
- Heatstroke: high body temperature (>103°F or 39°C), confusion, loss of consciousness, hot dry skin.
- Seek immediate medical attention if symptoms of heatstroke occur.
