What are signs of a serious heat-related illness?

Recognizing Heat Stroke

Heat stroke is a life-threatening condition that occurs when the body’s temperature regulation system is overloaded. This can happen when the body’s temperature rises above 103°F (39.4°C) due to excessive heat exposure. Recognize the signs of heat stroke by looking for symptoms such as a body temperature above 103°F (39.4°C), confusion or altered mental state, seizures, or loss of consciousness. If you suspect someone has heat stroke, call 911 or your local emergency number immediately.

Preventing Heat-Related Illness

Preventing heat-related illness requires awareness of the dangers of heat exposure and taking proactive steps to protect yourself. Always stay hydrated by drinking at least 1 quart (1 liter) of water per person per day in hot and humid environments. Additionally, wear light-colored, loose-fitting clothing to reflect the sun’s rays and reduce heat absorption. Avoid strenuous activities during the hottest part of the day (usually between 11 a.m. and 3 p.m.) and take regular breaks in shaded or air-conditioned areas.

First Aid for Heat-Related Illness

If you suspect someone has a heat-related illness, provide first aid by moving them to a shaded or air-conditioned area, removing excess clothing, and loosening tight clothing. Cool the person with cool water or a cool, wet cloth, but avoid direct contact with ice or cold water. Encourage the person to drink cool water, but avoid forcing them to drink if they are unable to do so. If the person’s condition worsens or they do not improve within 15-20 minutes, seek medical attention immediately.
