- Water is essential for optimal body function, as the human body is made up of about 50-70% water depending on age and composition.
- Proper hydration helps regulate body temperature, lubricate joints, protect organs and tissues, carry nutrients and oxygen to cells, and remove waste through urine, sweat, and bowel movements.
- Even mild dehydration can negatively affect cognitive functions such as memory, mood, concentration, and energy levels.
- Daily water intake needs vary individually based on factors such as age, sex, weight, activity level, and environmental conditions; general guidelines recommend about 6 to 8 cups for children and about 9 to 13 cups for adults.
- Besides drinking water, hydration can also be maintained through water-rich fruits and vegetables like watermelon, cucumber, and tomatoes.
- Avoid sugary drinks as they add unnecessary calories and can harm overall health; water remains the best hydration choice.
