What does it mean to have a fever but no fever?
Feeling hot refers to the sensation of body warmth. Feeling hot but not having a fever is generally caused by physiological factors, and it can also be caused by environmental factors or early stages of fever, among others. Here are some causes:
1. Physiological Factors: When emotions are overly excited, tense, or after vigorous exercise, the nervous system becomes excited, causing an increase in body surface temperature. Since this is a physiological phenomenon, fever symptoms do not appear, and it may be accompanied by sweating.
2. Environmental Factors: Prolonged exposure to high temperatures can cause the body to feel hot. At this time, the body's temperature regulation center functions normally, so it does not cause fever.
3. Early Stages of Fever: In the early stages of fever, the body's temperature regulation center can still function, resulting in the sensation of heat without actual fever. Usually, patients may also experience symptoms such as limb pain and fatigue.
Apart from the above reasons, there are other possible factors, such as hyperthyroidism and perimenopausal syndrome. It is recommended to closely monitor body temperature changes. If symptoms persist for a long time without improvement, it is necessary to seek medical attention promptly.
