MDMA decreases heat loss in the body by causing constriction of blood vessels near the skin and at times increasing heat production by muscles and the brain. Effects are amplified in people who become dehydrated and are unable to cool by sweating.

Consumption of water to achieve regulation of body temperature carries inherent risks. Over consumption may result in water intoxication and dilution of the blood that can cause swelling of the brain.

Physical exertion may lead to dangerously high body temperatures if precautions are not taken to remain cool.

Sustained high body temperatures result in muscle breakdown which in turn can cause renal failure and death.
