Heatwave Safety and Health Risks — Reading Comprehension

Imagine the air feeling thick and heavy, the sun beating down intensely, and even a fan only moving hot air around. This is what a heatwave feels like: a period of unusually hot weather that lasts for several days. These extreme heat events are becoming more common and intense, posing serious health risks to everyone, especially children, the elderly, and people with certain medical conditions.

Understanding the dangers of heatwaves is crucial for staying safe. Our bodies need to maintain a steady temperature. When it's very hot, our bodies try to cool down by sweating. But if it's too hot and humid, or if we don't drink enough water, our bodies can't cool down effectively. This can lead to dehydration, which means your body doesn't have enough fluids to work properly. Early signs of heat stress include feeling thirsty, tired, or dizzy.

More serious conditions can develop quickly. Heat exhaustion happens when your body overheats. Symptoms include heavy sweating, cold, clammy skin, fast weak pulse, nausea, muscle cramps, and fainting. If you experience these symptoms, it's important to move to a cool place, lie down, loosen your clothes, and drink water. The most dangerous condition is heatstroke, which is a medical emergency. Symptoms include a very high body temperature (over 103°F), hot, red, dry or damp skin, fast strong pulse, headache, dizziness, nausea, confusion, and even loss of consciousness. If you suspect heatstroke, call for emergency help immediately.

To minimize these risks during a heatwave, there are several key steps for heatwave safety. Stay hydrated by drinking plenty of water, even if you don't feel thirsty. Avoid sugary drinks or alcohol. Seek cool environments, such as air-conditioned buildings, or take cool showers. Wear light-colored, loose-fitting clothing and a wide-brimmed hat if you must go outside. Limit strenuous outdoor activities, especially during the hottest parts of the day (usually 10 AM to 4 PM). Never leave children or pets in a parked car, as temperatures inside can rise very quickly. By following these preventive measures, we can protect ourselves and our communities during periods of extreme heat.

Interesting Fact: The hottest temperature ever recorded on Earth was 134°F (56.7°C) in Death Valley, California, on July 10, 1913.
