Sunstroke, also known as heatstroke, is a life-threatening medical emergency where the body's temperature regulation fails, leading to a core temperature of 104°F (40°C) or higher. While many people wonder what is the best medicine for sunstroke, the most critical intervention is immediate physical cooling, not pharmaceutical drugs. Delays can be fatal or cause permanent organ damage.

The classic clinical mnemonic for anticholinergic overdose includes being 'hot as a hare,' a direct result of atropine's key anticholinergic property: the inhibition of sweating. This explains why does atropine cause hyperthermia by impairing the body's natural cooling system, leading to dangerous heat retention.

Overdoses of serotonin reuptake inhibitors or their use with other drugs may cause hyperthermia, leading to potentially life-threatening complications. This complex, drug-induced condition can result from various medications and requires prompt medical attention to avoid severe outcomes.

According to a 2024 study in *The Lancet*, drugs with high anticholinergic properties were found to increase core body temperature during heat stress at air temperatures above 30°C. Yes, anticholinergic medications can cause hyperthermia, a dangerous elevation of body temperature that can lead to heatstroke and other serious complications.

Studies show that taking medications with strong anticholinergic properties is associated with a two-times greater risk of heat-related illness and death [1.2.1]. The critical question is, do anticholinergics increase body temperature and how significant is this risk?

Anhidrosis, or the inability to sweat, is a well-documented side effect of the medication atropine, significantly impacting the body's ability to regulate temperature. This occurs because atropine blocks the specific nerve signals that command sweat glands to produce sweat. Understanding what does atropine do to sweat is crucial for managing this effect, particularly in hot weather or during physical exertion, where overheating and heatstroke are significant risks.

According to medical experts, fever, or hyperthermia, is a classic and potentially dangerous symptom of anticholinergic toxicity, often described by the mnemonic "hot as a hare". This occurs when a person is exposed to excessive anticholinergic agents, leading to a cascade of effects on the body's thermoregulation.

Atropine, an anticholinergic medication, is known to inhibit sweat gland activity, a side effect that can lead to an increase in body temperature, or hyperthermia. The question, **Does atropine increase temperature?**, is particularly relevant for vulnerable patients like infants and those in hot environments, where this effect can become dangerous.

Approximately 41% of people report experiencing night sweats, and this discomfort can make you wonder, "Why do I get so hot when I lay down in bed?". Understanding the link between pharmacology, your body's internal thermostat, and other triggers is key to uncovering the cause and finding a solution for your nocturnal overheating.

While excessive sweating is a common side effect of pyridostigmine, the medication does not typically cause a fever. A fever may indicate a more serious condition, such as a drug-induced hypersensitivity reaction or an infection, and requires prompt medical evaluation.
