Heat syncope

Heat Syncope

Heat syncope (pronounced: /ˈhiːt ˈsɪŋkəpi/), also known as heat collapse, is a form of syncope or fainting that is primarily caused by prolonged exposure to high temperatures.

Etymology

The term "heat syncope" is derived from the Greek words "heat" (thermos) and "syncope" (synkope), which means "cutting off" or "interrupting".

Definition

Heat syncope is a condition characterized by a sudden and brief loss of consciousness associated with exposure to high environmental heat. It is often accompanied by symptoms such as dizziness, lightheadedness, and a feeling of faintness.

Causes

Heat syncope is primarily caused by prolonged exposure to high temperatures, which leads to dehydration and a decrease in blood pressure. This can result in inadequate blood flow to the brain, causing a person to faint. Other factors that can contribute to heat syncope include physical exertion, inadequate fluid intake, and wearing heavy clothing in a hot environment.

Symptoms

The main symptom of heat syncope is a sudden and brief loss of consciousness. Other symptoms can include dizziness, lightheadedness, pale skin, and a weak pulse.

Prevention and Treatment

Prevention of heat syncope involves staying hydrated, avoiding prolonged exposure to high temperatures, and wearing light clothing in hot environments. Treatment typically involves moving the person to a cooler environment, having them lie down, and rehydrating them with fluids.
