A heatwave is caused by a system of higher atmospheric pressure. In a high pressure system, air from upper levels of the atmosphere descends and rotates outward. As it comes down, it becomes compressed, which increases its temperature and dries it out.
The most common causes include heat stroke and adverse reactions to drugs. The former is an acute temperature elevation caused by exposure to excessive heat, or combination of heat and humidity, that overwhelms the heat-regulating mechanisms.
