As we embark on our exploration of the potential benefits of using a hot tub when afflicted by a fever, it is crucial to establish a clear understanding of what constitutes a fever. A fever, in medical terms, is defined as an elevated body temperature that surpasses the normal range, typically above 37.5°C (99.5°F) for adults and 38°C (100.4°F) for children.
This rise in body temperature is a natural response triggered by the immune system as it combats infections or illnesses. While a fever can be an uncomfortable experience, accompanied by symptoms such as chills, sweating, and fatigue, it is important to recognize that it is a protective mechanism employed by the body to fight off harmful pathogens.
