Ice-cold water seems to be one of the best thirst-quenchers after a hard workout, but doctors say it can cause not only indigestion but actually hinder your muscles from relieving fatigue.
The digestive ability of the stomach slows down right after exercising because blood supply is focused mainly on the muscles instead of the digestive organs. Drinking cold water overtaxes already weak digestive functions.
Hong Jong-ki at CHA University said, "If cold water makes contact with our stomach, the organ exerts energy to match the water temperature with that of the body, and its function weakens as a result.
As the stomach shrinks, the result can be indigestion, stomach aches and diarrhea. That means muscles could take longer to relax as well. Hong said, "The muscles that control breathing can also tense up from drinking cold water. This could mean it takes longer to relive fatigue."
For the same reason, cold showers are not recommended after workouts.
Drinking 250 to 300 ml of lukewarm water is much better, and better still are electrolyte drinks that replenish salt lost from sweating, because drinking too much water can lead to an electrolytic imbalance, causing dizziness and nausea.
