Water is essential for human life and helps our bodies perform many vital functions. Blood contains over 90% of water, which helps circulate oxygen throughout the body. Your body uses water to maintain its temperature, remove waste, and lubricate joints. Physiologists agree that men need approximately 15.5 cups (3.7 liters), while women need approximately 11.5 cups (2.7 liters) of water a day to stay healthy. The formula for determining how much water you should drink each day requires that you get 35 milliliters of water for every 1 kilogram you weigh.

Water is the most important substance in your body. If you do not get enough water, your body will suffer from dehydration and may experience symptoms such as headaches, fatigue, and constipation. Additionally, dehydration can cause a drop in blood pressure which can result in lightheadedness or dizziness. When people experience these symptoms they generally look for ways to increase their intake of water by drinking more or eating foods with high water content such as fruits and vegetables.

In addition to being essential for survival, water plays several crucial roles in maintaining good health:

  • Water transports nutrients and oxygen to cells throughout the body; without it, we could not survive long enough to die from thirst!
  • It helps regulate body temperature by acting as an insulator against heat/cold.

Functions of water in the human body

Water is essential for life. It helps our bodies perform many vital functions, including regulating body temperature, removing waste, lubricating joints, and maintaining blood pressure and blood sugar levels. Water also plays a role in kidney function. The amount of water you need per day depends on a variety of factors including age and activity level. Your daily intake should be based upon the number of calories you’re consuming each day so that you’re getting plenty of fluids with your food intake as well as enough plain drinking water throughout the day (about six to eight glasses).

If you’re trying to lose weight or are underweight due to illness or injury, it’s important not just how much water you drink but also what type: plain water (tap or filtered), flavored sparkling waters.

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.

Blood performs many important functions within the human body, including:

  • Transporting oxygen from the lungs or gills to tissues throughout the body (via red blood cells)
  • Carrying nutrients from one part of the body to another (via red blood cells)
  • Removing carbon dioxide from the tissue through respiration or expiration (via red blood cells)

Water helps regulate body temperature, remove waste, lubricate joints and maintain its shape. In addition to these functions, water plays an important role in the following:

  • Maintaining flexibility of cells and tissues
  • Maintaining elasticity of the skin and muscles
  • Supporting the integrity of internal organs

How much water should you drink?

A general guideline is eight glasses of water a day which is equal to roughly two liters. This is not a strict rule, but rather an average. It’s best to start with this amount and see how your body responds after a few days. If you find yourself getting thirsty more frequently, try increasing your daily consumption by one or two glasses at a time until you reach the point where you feel satisfied.

If you find yourself drinking too much water (more than eight glasses), it’s possible that there could be an underlying medical cause for this such as diabetes or certain medications that increase fluid retention in the body. If you experience symptoms such as dizziness/fainting spells/extreme thirst/urinary tract infections, please consult your doctor immediately so he or she can investigate further!

You should also consider other lifestyle factors such as whether you live in a dry climate or have been ill recently as these factors can impact your water intake needs as well.

If you are pregnant, breastfeeding, or diabetic, then it is important to drink extra water so that your baby’s development is not affected by dehydration.


How much water should I drink?

In general, you should try to drink between half an ounce and an ounce of water per pound of body weight.

Why do I pee so much when I drink water?

When you drink more, you’ll pee more. Your body is more than 60% water, so if you’re drinking the correct amount of water for your size, you’ll be drinking a lot of water.

Is peeing 20 times a day normal?

Regularly urinating more than seven times per day may be normal for some people and may not be a sign of a health problem.
