No, body temperature does not generally rise when a person is tired. In fact, body temperature tends to decrease slightly as the body prepares for sleep. This decrease in body temperature is a natural part of the body’s circadian rhythm, which helps regulate the sleep-wake cycle.
However, if a person is experiencing other symptoms along with tiredness, such as fever or inflammation, their body temperature may rise as a result of those conditions. Additionally, certain medications and medical conditions can cause an increase in body temperature, regardless of tiredness.
So, while tiredness alone does not typically cause a rise in body temperature, other factors may contribute to an increase in body temperature.
