Cold Drinks in Summer: The Hidden Risks a Gastroenterologist Reveals

It’s a scorching July afternoon, the sun blazing overhead, and the instinctive reach for a glass of ice‑cold lemonade feels almost reflexive. Yet, Dr. Ananya Mehta, a seasoned gastroenterologist, says that this seemingly harmless habit might be doing more harm than good.

When you gulp down a frosty beverage, the sudden chill hits the lining of your throat and stomach. Your body, ever the diligent thermostat, works overtime to restore its core temperature. This ‘thermal shock’ can trigger a cascade of physiological responses – from increased heart rate to a surge in metabolic heat production – that paradoxically make you feel warmer.

Beyond the heat factor, the cold assault can irritate the delicate mucosal layer of the gastrointestinal tract. For some, especially those prone to acidity or irritable bowel issues, this can translate into stomach cramps, bloating, or a sudden bout of indigestion. It’s a classic case of the cure feeling like the problem.

“People assume that because the drink is cold, it will cool them down internally,” Dr. Mehta explains. “In reality, the body’s effort to re‑warm the fluid can generate extra heat, and the abrupt temperature change can disturb gut motility.” She adds that the phenomenon is more pronounced in individuals with existing digestive sensitivities.

So, what’s the smarter way to stay refreshed? Experts recommend opting for drinks that are cool rather than ice‑cold – think room‑temperature water infused with mint or cucumber. These choices hydrate without shocking the system. Additionally, sipping slowly rather than gulping allows the body to adjust gradually, minimizing the thermal jolt.

In short, while an icy soda might seem like the ultimate summer savior, it could be secretly turning up the thermostat inside you. Choose milder temperatures, stay hydrated, and let your body handle the heat the way it was meant to.
