On sweltering days, gulping a glass of fridge-cold water immediately after coming in from the heat may feel instantly refreshing, but doctors and some studies warn it can cause several health problems. Medical experts say that sudden ingestion of very cold water can constrict blood vessels in the digestive tract, slowing digestion and increasing the risk of constipation, bloating and indigestion.
Research and clinicians also note that an abrupt temperature change can stimulate the vagus nerve, a key part of the nervous system that helps regulate heart rate. Rapid cooling of this nerve may trigger sudden changes in heart rhythm in susceptible people.
Drinking extremely cold water while overheated may also promote excess mucus production in the airways, raising the chance of respiratory congestion. People who already suffer from sinus problems or migraines may find their symptoms aggravated; sore throat, nasal cold and coughing are also commonly reported after abrupt cold exposure.
Physiologically, drinking very cold water right after prolonged sun exposure disrupts the body’s thermal balance. This “thermal shock,” as it is sometimes described, can temporarily weaken immune defenses and make people more prone to falling ill.
To stay safe in hot weather, doctors recommend avoiding ice-cold water from the refrigerator. Instead, choose water at room temperature or slightly cool. Drinking from an earthen or clay pot is often suggested because it naturally keeps water cool without being icy and is gentler on the body. Experts also advise waiting about 10 to 15 minutes after coming in from the sun-sitting in the shade or a cool spot until your body temperature settles-before drinking.
Small changes in how and when you drink can preserve the immediate comfort of cooling down while reducing the chance of digestive upset, respiratory trouble or other heat-related health issues.
