Introduction
Fever refers to an elevated body temperature. In general, feeling hot after swimming without an actual fever may be caused by water temperature, the body's thermoregulation, excessive exercise, infection, or allergies, and appropriate management is needed accordingly. If the swimming water is warm or the environment is hot, it can increase heat absorption by the body and impair heat dissipation, leading to a sensation of heat, which is considered normal.
Fever refers to an elevated body temperature. In most cases, feeling hot after swimming without actually having a fever may be caused by water temperature, the body's self-regulated heat production, excessive exercise, infection, allergies, or other factors, which require appropriate management. The details are as follows:
1. Water Temperature
If the swimming water is too warm or the environment is hot, it can increase heat absorption and impair the body's ability to dissipate heat, leading to a sensation of feverishness. This is considered normal. It is recommended that individuals take a shower promptly; discomfort usually subsides gradually after resting for a while.
2. Self-Regulated Heat Production
The body generates heat during swimming. If excessive heat is produced, one may feel hot, but the body will naturally regulate itself afterward. Choose swimming venues with suitable water temperatures. This is a normal phenomenon; individuals should pay attention to staying warm and avoid catching a chill.
3. Excessive Exercise
Swimming is a relatively intense physical activity. Swimming for too long or at too high an intensity can accelerate metabolism and generate excess heat, causing the body to feel feverish. Individuals should avoid overexertion and plan their swimming duration and intensity appropriately.
4. Infection
During swimming, exposure to bacteria or viruses in the water may lead to infection and subsequent fever. However, symptoms are generally mild and not severe enough to cause significant fever. Showering before and after swimming and maintaining good personal hygiene can help prevent infection. If needed, patients may follow medical advice to take medications such as cefprozil dispersible tablets or cefaclor dispersible tablets.
5. Allergy
Some individuals may have allergic reactions to chemicals in swimming pools, such as chlorine or disinfectants, which can cause skin warmth or irritation. Wearing breathable and comfortable swimwear and avoiding irritating skincare products is advised. Patients may follow medical guidance to take antihistamines such as loratadine tablets or cetirizine hydrochloride tablets.
If the fever persists for a prolonged period or is accompanied by other symptoms, prompt medical evaluation and treatment are recommended.
