Can you drink ice water after intense exercise?

Generally, it is not recommended to drink ice-cold water immediately after intense exercise, as it may cause physical discomfort. The detailed explanation is as follows:

After intense physical activity, the body is in a highly excited state, with blood vessels throughout the body dilated and blood pressure possibly elevated. Drinking ice-cold water at this time may irritate the gastrointestinal tract, causing rapid contraction of the gastric mucosa, which could lead to gastric spasms and symptoms such as abdominal pain, nausea, and vomiting. The sudden intake of cold water may also cause abrupt intestinal contractions, which is detrimental to health and may result in diarrhea. Additionally, after strenuous exercise, the heart is already working at an accelerated rate and under significant strain; consuming ice water may induce persistent capillary constriction and increase peripheral vascular resistance, thereby further increasing the burden on the heart. Instead, after intense exercise, it is better to drink warm water or light salt water to replenish lost fluids and energy, which can help alleviate physical fatigue to some extent.

After vigorous exercise, one should also pay attention to resting and relaxing, performing appropriate stretching and massage to aid the body in recovering more quickly.
