Quick Answer
After heat exposure, cool the body with gradual transitions from intense activities to rest, drinking plenty of water, and using cooling methods such as spraying with water or wetting clothing. Remove excess clothing and apply cool compresses or wet cloths to the neck, wrists, and forehead. Seek shade or air-conditioning if possible.
Cooling Methods
When cooling down, it’s essential to avoid sudden, extreme changes in temperature. Instead, use a gradual cooling process by spraying the body with water or wetting clothing to reduce radiant heat gain. This technique can lower body temperature by as much as 1.5°C in just 10-15 minutes. Another effective method is to soak cloth in cold water, wring it out, and apply it to the neck, wrists, and forehead.
Hydration and Rest
Drink plenty of water to replenish lost fluids and electrolytes. Aim to consume at least 1-2 liters of water per hour, or more if you’ve been engaging in intense activities. Rest in a shaded area or air-conditioned space to allow the body to recover from heat stress. If possible, remove excess clothing to promote airflow and speed up cooling.
Medical Attention
If symptoms persist or worsen, seek medical attention immediately. Be aware of signs of heat stroke, such as a body temperature above 40.6°C, confusion or slurred speech, seizures, or loss of consciousness. If you suspect someone is experiencing heat stroke, call emergency services and provide cool water or a cold compress to help lower their body temperature until medical help arrives.
