Soda Vs Water: Carbonation Tricks The Brain Into Feeling Extra Refreshment

On April 22, 2026, lifestyle experts explained why sodas seem more refreshing than water during summer. While hydration is the same, the sensory experience of carbonation makes fizzy drinks feel colder and more satisfying.

Why Soda Feels Colder

Carbonation effect: Carbon dioxide bubbles stimulate receptors linked to cooling and irritation, tricking the brain into registering the drink as colder.

Acidity: Ingredients like citric and phosphoric acid sharpen the crisp sensation, enhancing the perception of chill.

Sound and fizz: The hiss of opening a can and the fizzy pour add psychological cues of refreshment. 

Role Of Sugar And Energy

Sugary sodas provide a quick energy burst, which can feel like instant relief in hot weather. However, this effect is short-lived, and excess sugar may contribute to dehydration over time. Zero-sugar sodas are increasingly popular among younger consumers, accounting for nearly 30% of India’s soft drink market. 

Water’s Cooling Power

Plain water, when served equally cold, cools the body just as effectively. It hydrates without added sugar or acids, making it the healthier long-term choice for beating the heat.
