What Are Amphetamines?
Amphetamines are synthetic substances that stimulate the release of certain neurotransmitters in the brain, such as dopamine and norepinephrine. These neurotransmitters play a role in regulating mood, attention, and alertness. Amphetamines come in various forms, including tablets, capsules, or powder, and can be taken orally, inhaled, or injected.
Effects of Amphetamines on the Body
Amphetamines have several effects on the body due to their impact on neurotransmitter activity. They can increase heart rate, blood pressure, and body temperature. The rise in core body temperature is a notable effect of amphetamine use. According to a study published in the journal PMC, amphetamine slows down the rise in core body temperature during exercise, which can decrease exhaustion without affecting oxygen consumption. However, it's important to note that amphetamine can still lead to dangerous overheating of the muscles and exertional heat stroke.
The administration of amphetamines alters both heat production and heat dissipation within the body. The increase in body temperature caused by amphetamines can lead to exertional heat stroke and potentially dangerous overheating of the muscles. In fact, a study published in PMC found that the muscle temperature at the end of exercise was significantly higher in the amphetamine-treated group compared to the control group.
The rise in body temperature from amphetamines is attributed to the drugs' ability to speed up metabolism, increase heart rate, and elevate blood pressure. This increase in core body temperature can have serious consequences. In severe cases, it can lead to muscle breakdown, kidney damage, and in extreme circumstances, even death.
Understanding the effects of amphetamines on body temperature is crucial for recognizing the risks and dangers associated with their use. It is important to seek medical attention if you or someone you know experiences symptoms of overheating or hyperthermia after using amphetamines.

Amphetamines, such as dextroamphetamine and methamphetamine, increase the body's core temperature by speeding up metabolism and elevating heart rate and blood pressure. These stimulant drugs stimulate the central nervous system, leading to an increase in energy expenditure and heat production within the body.
The administration of amphetamines has been found to increase heat dissipation in the core, which masks or delays fatigue during exercise. This effect can lead to an increased tolerance for physical exertion, as the rise in core body temperature is slowed down. However, it is important to note that the rise in body temperature can still occur, potentially leading to exertional heat stroke and dangerous overheating of the muscles.
Mechanisms of Heat Production and Dissipation
Amphetamines not only affect heat production but also impact heat dissipation within the body. The increased metabolism caused by amphetamines leads to heightened heat production. As the body's metabolic processes are accelerated, more energy is converted into heat.
Heat dissipation, on the other hand, refers to the body's ability to release excess heat and maintain a stable core temperature. When amphetamines increase body temperature, the natural mechanisms of heat dissipation, such as sweating and vasodilation (expansion of blood vessels), may be affected. This can disrupt the body's ability to effectively cool down, potentially leading to dangerous overheating.
It is important to recognize that amphetamine-induced hyperthermia can have severe consequences. In severe cases, the increase in body temperature caused by amphetamines can result in muscle breakdown, kidney damage, and, in extreme circumstances, even death. Therefore, understanding the risks and dangers associated with amphetamine use and recognizing the symptoms of hyperthermia is crucial for seeking timely help and taking appropriate measures.
