Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Heat exhaustion is a precursor to heat stroke, a severe form of heat-related illness. Heat stroke is more likely than heat exhaustion to cause palor, hot and dry skin, syncope, and dysfunction of the central nervous system (e.g., altered mental status, loss of spatial awareness, loss of bodily movement control, seizures, etc.).
Heat exhaustion - Can be a precursor of heatstroke; the symptoms include heavy sweating, rapid breathing and a fast, weak pulse. Heat syncope - Fainting or dizziness as a result of overheating. Heat edema - Swelling of extremities due to water retention following dilation of blood vessels in response to heat. Heat cramps - Muscle pains that ...
Active muscles produce heat, but once you stop exercising, that heat dissipates and can ultimately lower your body temperature, Dr. Quinlan says. You might even develop muscle cramps, nausea, or ...
When the body cannot cool itself off sufficiently, symptoms of heat stress—including nausea, vomiting, loss of coordination, shortness of breath, dizziness and more—can occur. So-called strong ...
Extreme heat can cause dizziness and be troublesome for older people with heart conditions. Hot yoga isn't recommended for people with arthritis, heart disease, high or low blood pressure, and ...
Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F), [4] along with red skin, headache, dizziness, and confusion. [2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke. [5] The start of heat stroke can be sudden or ...
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.
