Hydration and Aging – Why Thirst Declines and How to Stay Hydrated

 

Did you know the body's thirst mechanism becomes less sensitive as we age? By the time an older adult feels thirsty, mild dehydration has already set in.

Risks of Dehydration in Older Adults

• Orthostatic Hypotension: Sudden drops in blood pressure when standing up, causing lightheadedness and fall risks.

• Joint Friction: Cartilage requires water content to cushion joints properly during walking.

• Cognitive Fog: Even 2% dehydration impairs short-term recall and reaction speeds.

Action Tip: Aim for 8 glasses of fluid daily, incorporating water-rich foods like cucumbers, soups, and citrus fruits.
