Introduction
During exercise in hot environments, the body tends to sweat and generate substantial heat. Drinking iced water in moderation at this time can effectively lower body temperature, aid in heat dissipation, and reduce heat stress caused by physical activity. Additionally, cold water stimulates cooling receptors in the mouth and throat, sending signals to the brain that temporarily enhance exercise endurance and performance.
Generally, it is considered acceptable to drink ice-cold water during exercise when the ambient temperature is high, the body needs cooling down, and the individual has no adverse reactions to cold water. Conversely, drinking ice-cold water during exercise should be avoided when the body is already in a cold state, when body temperature drops sharply after physical activity, or when the individual experiences negative reactions to cold water. A detailed explanation follows:
During exercise in hot environments, the body tends to sweat and generate substantial heat. In such cases, consuming an appropriate amount of ice-cold water can effectively lower body temperature, aid heat dissipation, and reduce heat stress caused by physical exertion. Additionally, cold water stimulates the cooling receptors in the mouth and throat, sending signals to the brain that may temporarily enhance exercise endurance and performance.
However, if the body is already cold or experiences a sharp drop in temperature after exercise, drinking ice-cold water may further decrease body temperature, impair blood circulation and muscle recovery, and potentially lead to adverse effects such as shivering or hypothermia. Individuals with weak gastrointestinal function should also avoid ice-cold water to prevent issues like stomach pain or diarrhea.
It is recommended to maintain a healthy lifestyle, ensure sufficient sleep, improve dietary habits, adjust physical condition, and promote overall health.
