The search results do not contain information about cooling down an overheated horse, but they do contain information about heatstroke in humans. The following answer will address heatstroke in general.
Heatstroke is a dangerous condition caused by prolonged exposure to high temperatures and humidity, where the body’s temperature rises to dangerous levels of 104 to 110 °F (40 to 43 °C) or even higher. Cooling the body is critical; ice-water baths or packs combined with massage to promote circulation are effective. Cooling should be stopped when the individual’s temperature reaches 102 °F (39 °C) but should be restarted if the temperature rises again. Seeking professional medical care is also important to manage potential circulatory issues and brain damage.
What Are the Signs of Heatstroke?
Heatstroke symptoms include headache, dizziness, flushed or paler skin, rapid breathing, disorientation, nausea or vomiting, and a high internal body temperature, often exceeding 104 °F (40 °C). Immediate medical attention is essential if these symptoms appear, as heatstroke can be life-threatening if not properly treated.
How Does the Body Normally Cool Itself?
The body typically eliminates heat through radiation and convection from the skin and lungs, as well as through the evaporation of sweat. However, when the surrounding environment is very hot and humid, these methods become less effective, and the body may struggle to maintain a safe internal temperature.
What is Heat Exhaustion?
Heat exhaustion, or heat prostration, occurs when a person collapses due to dehydration or inadequate circulation. Unlike heatstroke, heat exhaustion is characterized by a moderate or absent elevation of body temperature, heavy sweating, and possible heat cramps. Treatment involves lying down in a cool place and drinking water with added salt.
