Introduction
In general, you should not drink ice-cold water immediately after running. Drinking cold water can strongly stimulate the gastrointestinal tract, cause blood vessel constriction, lead to blood pressure fluctuations, and place extra stress on the heart. Additionally, consuming cold water may cause pores to contract, impairing sweat release and thereby hindering the body's cooling mechanism. It is recommended to drink适量 amounts of room-temperature water after running to effectively replenish fluids and electrolytes.

Generally speaking, it is not recommended to drink ice-cold water immediately after running, as it may cause discomfort.

During running, blood circulation accelerates, body temperature rises, and blood flow to the gastrointestinal tract decreases relatively, leading to weakened intestinal motility. Drinking ice-cold water at this time can strongly stimulate the gastrointestinal tract. The cold liquid may cause a sudden constriction of blood vessels in the stomach and intestines, resulting in spasms that can trigger abdominal pain, diarrhea, and other uncomfortable symptoms. From a cardiovascular perspective, the heart is already under increased stress and heart rate is elevated after exercise. Suddenly consuming ice-cold water can induce blood vessel constriction and blood pressure fluctuations, placing additional strain on the heart and increasing its workload.

In addition, after running, the body dissipates heat through sweating to maintain thermal balance. Drinking ice-cold water may cause pores to contract, impairing sweat secretion and thereby interfering with the body's natural cooling mechanism. This could potentially lead to heat accumulation inside the body, making you feel even more uncomfortable.

It is advisable to rest for a while after running, allowing your body to stabilize before drinking an appropriate amount of room-temperature water. This effectively replenishes fluids and electrolytes while avoiding unnecessary harm to the body.
