Optimal water intake hinges on weight, activity, and climate, yet hydration is non-negotiable for health, including oral wellness.

Water cushions joints, brightens skin, aids kidneys, and flushes waste. It also fuels saliva production, a natural germ fighter. Dehydration dries the mouth, inviting microbes and a milky coating.

Sip water often and tote a reusable bottle for easy access. Signs of dehydration include dark urine, fatigue, headaches, dizziness, and scant urination.

General advice suggests about 15.5 cups (3.7 L) of fluids daily for men and 11.5 cups (2.7 L) for women, counting drinks and water-rich foods. Hot climates or heavy exercise call for more.

Prioritize hydration by drinking regularly, eating juicy produce, and limiting diuretics like caffeine and alcohol.
