Cold Water in Scorching Heat? Experts Warn It May Be Harming Your Body
As temperatures soar across India, reaching for an ice-cold bottle of water feels almost automatic. But health experts are now warning that excessive consumption of chilled water during extreme summer heat may not be as harmless as it seems.
Doctors say that while cold water provides instant relief, it can negatively affect digestion, blood circulation, and even the nervous system in some cases. According to medical experts, drinking extremely cold water too quickly can trigger sudden spasms in the food pipe and stomach, leading to chest discomfort, headaches, or dizziness.
Some specialists have even linked ice-cold beverages to rare incidents of temporary unconsciousness. Experts explain that the sudden temperature shock may stimulate the vagus nerve — a nerve connected to heart rate and blood pressure — potentially causing the body to briefly shut down or feel faint.
Health professionals also caution that chilled water may worsen sore throats, slow digestion, trigger migraines, and constrict blood vessels. For people with heart conditions or blood pressure issues, this sudden cooling effect could place extra strain on the cardiovascular system.
Doctors particularly advise avoiding ice-cold water immediately after intense workouts, prolonged sun exposure, or during illnesses like cough, flu, or stomach infections. Instead, moderately cool or room-temperature water is considered safer and more effective for hydration.
As heatwaves continue to grip several parts of the country, experts say staying hydrated is essential — but how you hydrate matters just as much. Sometimes, that freezing bottle from the fridge may offer quick comfort, but your body could be paying the price later.
