Importance of Water in Human Body

• The average human body is composed of 55-60% water, with babies being 75% water at birth and dropping to 65% by their first birthday.
• Water in the body plays a crucial role in cushioning and lubricating joints, regulating temperature, nourishing the brain and spinal cord, and is present in various body parts like the brain, heart, lungs, and bones.
• Daily, humans lose 2-3 liters of water through sweat, urine, breathing, and bowel movements, necessitating the need to drink water to maintain a balanced water level to avoid dehydration or over-hydration.
• Dehydration can lead to drops in energy, mood, skin moisture, blood pressure, cognitive impairment, and even temporary brain shrinkage, while over-hydration can cause sodium electrolyte dilution and water intoxication.
• The recommended daily water intake varies from 2.5-3.7 liters for men and 2-2.7 liters for women, with factors like weight, environment, health, activity level, and age influencing the amount needed.
