How to recognize the early stages of heat-related illnesses?

Recognizing Heat Exhaustion Symptoms

Heat exhaustion often begins with heavy sweating, which can be accompanied by pale or flushed skin. The individual may exhibit a fast and weak pulse, typically above 100 beats per minute, and their breathing may be rapid and shallow. Additional symptoms include nausea or vomiting, dizziness or fainting, and headaches. If you notice these symptoms in someone, have them lie down in a cool place and loosen their clothing to improve airflow and promote heat loss.

Cooling Methods for Heat-Related Illnesses

To cool the body effectively, use a combination of water-based and evaporation-based cooling methods. For water-based cooling, apply cool water to the individual’s forehead, neck, and wrists, or use a cool compress. Evaporation-based cooling involves fanning the individual to increase airflow and enhance evaporation of sweat. You can also use a wet cloth or towel to help cool the body through evaporation. Aim to cool the body to a temperature below 102°F (39°C) to prevent further heat-related damage.

Preventing Heat-Related Illnesses

Preventing heat-related illnesses is often more effective than treating them after they occur. Stay hydrated by drinking plenty of water, aiming for at least 8-10 cups (64-80 ounces) of water per day. Take regular breaks in cool, shaded areas to avoid prolonged exposure to direct sunlight. Wear lightweight, light-colored clothing that allows for airflow and helps to reflect the sun’s rays. Limit strenuous activities to early morning or evening hours when the temperature is cooler. By taking these precautions, you can reduce your risk of developing heat exhaustion or heatstroke.
