The real culprit is usually not temperature, but behavior. Think about it: when you’re hot and thirsty, you don’t sip—you gulp. Guessing you do it too.
Gulping traps air bubbles in the water you swallow. Plus, carbonated cold drinks (sparkling water, soda) are obvious gas bombs, but even plain cold water can cause aerophagia—the fancy term for swallowing air.

Another sneaky factor: cold beverages can constrict blood vessels in your stomach lining temporarily. This isn’t bloating, but it can create a tight, uncomfortable sensation that mimics it.
The Real Villain: Dehydration or Over-hydration?
Ironically, not drinking enough water (being dehydrated) causes your body to hold onto every drop—leading to that water-retention “puffiness.” Cold water is just the messenger.
On the flip side, drinking a massive volume of any temperature liquid at once stretches your stomach walls. That stretch signals “fullness” and can feel bloated for twenty minutes.
A little side note: your stomach can hold about one liter comfortably. Anything beyond that, and you’re in distension territory. Cold or hot, it doesn’t care.
