Is 37.7°C considered a fever?

Generally speaking, fever refers to an elevated body temperature, with 37.7°C considered as a fever. If discomfort occurs, timely medical attention is recommended. The detailed explanation is as follows:

The normal body temperature in humans typically ranges between 36.0-37.2°C. When body temperature reaches 37.7°C, it has exceeded the upper limit of the normal temperature range and falls into the category of low-grade fever. Body temperature is precisely regulated by the hypothalamic thermoregulatory center, which maintains body temperature at a relatively stable level through various physiological mechanisms. Fever is usually a defensive response of the body to various pyrogens. These pyrogens may be exogenous pathogens, such as toxins released by microorganisms like bacteria, viruses, and fungi after infecting the body, or they may be substances produced during internal inflammatory responses, such as those occurring in autoimmune diseases when body tissues become inflamed. When these pyrogens affect the body, the thermoregulatory center increases heat production and reduces heat dissipation, resulting in elevated body temperature.

If body temperature reaches 37.7°C, it may be accompanied by some mild symptoms such as slight headache, fatigue, and muscle aches. At this stage, physical cooling measures can be taken first, such as wiping the forehead, armpits, and groin areas with lukewarm water to help dissipate heat. At the same time, it is important to rest adequately, drink plenty of water, and ensure good indoor air circulation. If the temperature continues to rise or other severe symptoms develop, prompt medical attention is necessary to determine the cause of the fever and receive appropriate treatment.
