As we age our body’s regulation of fluid intake and thirst declines. As little as a two percent water deficit can produce fatigue, confusion or mood changes.
Recent study results suggest that proper hydration may slow down aging and prolong a disease-free life. About half of people worldwide don’t meet recommendations for daily total water intake, which starts at six cups.
The National Academies of Medicine suggest that most women consume around 6-9 cups of fluids daily and for men, 8-12 cups.
