The human body consists of about 73% water, and maintaining proper hydration is essential for health. Determining how much water to drink daily depends on individual needs, which vary by health conditions and environment. The National Academy of Medicine sets a general guideline of 13 cups for men and nine cups for women, though these targets adjust based on activity levels and climate.
Personal Fluid Needs
Pregnant individuals should consume 8 to 12 cups to support digestion, amniotic fluid, and waste removal. Illnesses like fever, vomiting, or diarrhea increase the need for fluids to prevent dehydration. Even the temperature of water matters—drinking around 0.5 liters of warm water or hot water has been shown to increase basal metabolic rate, promoting thermogenesis by around 30%.
Strenuous exercise in hot or humid conditions demands more water.
The Impact on Body and Mind
Hydration influences both physical and mental well-being. Research from the University of California links higher water intake to improved mood, while a 2018 article in the World Journal of Psychiatry reported a clear link between drinking more water and a lower incidence of depression. Deakin University also found a link between adequate hydration and lowered anxiety levels.
Sufficient water intake helps control blood sugar by limiting vasopressin, a hormone that signals dehydration. Studies show drinking more than one liter of water a day reduced the risk of new-onset hyperglycemia by 28%.
Despite clear medical advice, many people struggle to meet hydration goals. Barriers like limited access or the availability of sugary drinks may explain why consumption remains below recommended levels.
Gauging Hydration and Fluid Sources
Thirst is an unreliable indicator, as it appears only after dehydration begins. Older adults may not notice thirst as readily.
Water intake doesn’t always come from drinking. Broth-based soups, gelatin, and fruit-infused water contribute to hydration. While bottled water is convenient, studies show no major quality difference between tap and bottled options, with some bottled brands containing more bacteria. Sparkling water provides the same benefits as still water and may appeal to those who dislike plain water. Caffeinated drinks require caution, as they act as diuretics and increase fluid needs.
Indonesia’s evolving approach to hydration and health reflects broader changes in public health strategies. Pharmacy practices now emphasize education on fluid balance, aligning with global efforts to improve wellness through better hydration habits.
