Heatwave Safety: Practical Tips for Hot Weather

A heatwave is a period of unusually hot weather for a location. High humidity can make hot conditions feel more intense because sweat evaporates less efficiently. The risks may be greater for older adults, young children, outdoor workers, and people without access to a cool place.

Reduce heat exposure

Schedule strenuous outdoor activity for cooler parts of the day when possible. Rest in shade or an air-conditioned place, wear lightweight loose-fitting clothing, and drink water regularly. Never leave children or pets in a parked vehicle.

Watch for signs of heat illness

Heavy sweating, weakness, dizziness, nausea, or headache can be warning signs of heat exhaustion. Move to a cooler place and seek medical advice if symptoms worsen or do not improve. Confusion, fainting, or very hot skin can indicate a medical emergency—contact local emergency services immediately.

Check local advice

Heat thresholds differ by region, and official warnings may account for humidity and overnight temperatures. Follow your local weather service and public-health guidance, especially during prolonged heat.
