Aim for regular sips rather than chugging, as your brain relies on steady hydration for focus, memory, and energy, and even mild dehydration can impair cognitive function.

Your gut communicates thirst relief to your brain within minutes, but the whole-body hydration process unfolds over time, with studies showing benefits from drinking water before tasks or after waking.

While not a definitive diagnosis, it's a quick, non-invasive way for clinicians to spot signs of impairment that warrant further neurological evaluation, particularly in conditions like Parkinson's-related dementia.
