Study Notes

Water in the Human Body

  • The human body is made up of approximately 55-60% water, which is distributed throughout the body.
  • Newborn babies have a higher water content, around 75%, similar to fish.
  • This water percentage decreases to 65% during the first year of life.

Functions of Water in the Body

  • Water is used to lubricate and moisten joints, regulate body temperature, and nourish the brain and spinal cord.
  • Water is not only found in blood, but also in other organs, such as the brain, heart, and muscles, with the brain and heart containing around 75% water.
  • Even seemingly dry organs, like bones, contain around 31% water.

Water Loss and Dehydration

  • We lose around 2-3 liters of water daily through sweat, urine, and breathing.
  • This water loss needs to be compensated for to maintain overall health and prevent dehydration.
  • Dehydration can lead to serious health issues, including decreased energy, dry skin, and even organ damage.

Importance of Hydration

  • Hydration is crucial for maintaining physical and mental health.
  • Drinking enough water helps to regulate body temperature, transport nutrients, and remove waste products.
  • Aiming to drink 2.5-3.7 liters of water per day for men and 2-2.7 liters for women is recommended, depending on weight, activity level, and climate.

Other Sources of Hydration

  • Fruits and vegetables, such as watermelon, cucumber, and broccoli, are made up of around 90% water and can contribute to daily hydration needs.
  • Even caffeinated beverages, like coffee and tea, can help to meet hydration needs.

Benefits of Hydration

  • Optimal hydration has been shown to reduce the risk of ischemia, help manage diabetes, and lower the risk of certain types of cancer.
  • Drinking enough water can make a significant difference in how we feel, think, and function on a daily basis.
