Body Water Percentages

  • Adult men's bodies are about 60% water, while women's are closer to 50% due to higher average body fat.
  • Infants have a higher water percentage (around 65%) and the elderly have less water than younger adults, often below 50%.

Water Input and Thirst

  • Daily water intake is roughly 2100 ml from food and drinks, plus 200 ml produced metabolically.
  • The body has a strong thirst reflex regulated by the hypothalamus, so listen to it for hydration.

Water Output

  • Insensible water loss (breathing, skin) is about 700 ml daily, and is difficult to control.
  • Other losses include sweat (100 ml at rest), feces (100 ml), and urine (1400 ml, but highly variable).
