Hydration is essential for the body to function properly.

Water makes up about 60% of the body’s weight and is involved in many important functions, including:

  • Transporting nutrients and oxygen to cells. Water helps to transport nutrients and oxygen from the blood to the cells. This is important for cell growth and repair.
  • Removing waste products. Water helps to remove waste products from the body through urination, sweating, and bowel movements. This is important for preventing toxins from building up in the body.
  • Regulating body temperature. Water helps to regulate body temperature by absorbing heat and releasing it through sweating. This is important for preventing heat stroke and other heat-related illnesses.
  • Lubricating joints. Water helps to lubricate joints and reduce friction. This is important for preventing joint pain and stiffness.
  • Protecting organs. Water helps to protect organs by cushioning them and preventing them from rubbing against each other.

Dehydration occurs when the body does not have enough water. This can lead to a variety of health problems, including:

  • Headache. Dehydration can cause the blood to thicken, which can put pressure on the brain and cause headaches.
  • Diarrhea. Dehydration can cause the stool to become hard and difficult to pass. This can lead to diarrhea.
  • Constipation. Dehydration can also cause the stool to become dry and hard, which can lead to constipation.
  • Muscle cramps. Dehydration can cause muscle cramps, especially in the legs.
  • Fatigue. Dehydration can cause fatigue, as the body does not have enough water to function properly.
  • Irritability. Dehydration can also cause irritability and mood swings.

It is important to drink plenty of fluids throughout the day to stay hydrated. The amount of fluids you need will vary depending on your activity level, climate, and overall health. However, most adults should aim to drink about 8 glasses of water per day. You can also get fluids from other sources, such as juice, milk, soup, and fruits and vegetables.

If you are unsure how much water you need to drink, talk to your doctor. They can help you determine the right amount of fluids for your individual needs.
