What Is a Heat Wave?

A heat wave is a prolonged period of unusually high temperatures that can significantly impact human health.

In the UAE, heat waves often occur during May to September, when temperatures can exceed 45°C and humidity levels increase, making conditions even more dangerous.

According to the National Integrated Heat Health Information System, extreme heat becomes especially dangerous when combined with humidity because it prevents the body from cooling effectively.

Essential Heat Wave Safety Tips

1. Stay Hydrated

Drink water frequently throughout the day, even if you do not feel thirsty. Avoid beverages containing caffeine or alcohol as they can contribute to dehydration.

Try to schedule outdoor activities early in the morning or later in the evening.

3. Wear Appropriate Clothing

Choose:

• Lightweight clothing
