Heat syncope is fainting as a result of overheating (syncope is the medical term for fainting). It is another stage in the same process as heat stroke it occurs under similar conditions and it is not distinguished from the latter by some authorities. The basic symptom of heat syncope is a body temperature above 40°C (104°F) with fainting with or without mental confusion which does occur in heat stroke. Heat syncope is caused by mild overheating with inadequate water or salt.
