Introduction
Taking sedatives can lower body temperature. However, if an allergic reaction occurs, it may lead to an increase in body temperature. Sedatives primarily act on the central nervous system, reducing its excitability to achieve calming and hypnotic effects. In daily life, it is recommended to use sedatives under a doctor's guidance and to monitor body temperature changes afterward, which can help in taking appropriate measures when necessary.

Generally, taking sedatives can cause body temperature to drop. However, if an allergic reaction occurs, it may lead to an increase in body temperature. The detailed explanation is as follows:

Sedatives primarily act on the central nervous system, achieving calming and hypnotic effects by inhibiting the excitability of the central nervous system. The body's temperature regulation center is located in the hypothalamus, which is also part of the central nervous system. After taking sedatives, the inhibitory effect on the central nervous system may affect the temperature regulation center, interfering with the normal temperature regulation mechanism, disrupting the original balance between heat production and heat dissipation, thereby causing a decrease in body temperature.

However, some individuals may be allergic to certain components in the sedatives they take, which can trigger the release of various inflammatory mediators such as histamine. These inflammatory mediators not only cause common allergic reactions like itching, rash, and rapid breathing but may also act on the body's temperature regulation center, raising the temperature set point and leading to an increase in body temperature.

In daily life, it is recommended to use sedatives under a doctor's guidance and closely monitor body temperature changes afterward, which can help in taking appropriate measures when necessary.
