Academic Summary: A 2026 study demonstrates that sparkling water significantly mitigates cognitive fatigue during prolonged, mentally demanding tasks. By activating TRP channels in the oral and pharyngeal cavities, carbonation sustains prefrontal cortex activity and prevents the pupil constriction typically associated with mental exhaustion. Unlike caffeinated beverages, this effect occurs without altering heart rate, blood glucose, or cortisol levels, offering a sustainable strategy for maintaining inhibitory control and performance in digital environments.
