We’ve always been told to drink more water, but why is this? Do we need it? How much should we drink?

1. Drinking Water Helps Maintain the Balance of Body Fluids.
Your body is composed of about 60% water. The functions of these bodily fluids include digestion, absorption, circulation, creation of salvia transportation of nutrients, and maintenance of body temperature.

2. Water Can Help Control Calories.
Dieters have been drinking lots of water as a weight loss strategy. Water doesn’t have any magical effects on weight loss, but substituting it for higher calorie beverages can certainly help.

3. Water Helps Energize Muscles.
Cells that don’t maintain their balance of fluids and electrolytes can result in muscle fatigue faster than a hydrated muscle. When muscle cells don’t have adequate fluids, they don’t work as well and performance can suffer.

4. Water Helps Keep Skin Looking Good.
Your skin contains plenty of water, and functions as a protective barrier to prevent excess fluid loss.

5. Water Helps Your Kidneys.
Body fluids transport waste products in and out of cells. Your kidneys do an amazing job of cleansing and ridding your body of toxins as long as your intake of fluids is adequate.

6. Water Helps Maintain Normal Bowel Function.
Adequate hydration keeps things flowing along your gastrointestinal tract and prevents constipation. When you don’t get enough fluid, the colon pulls water from stools to maintain hydration, and the result is constipation.


So how much water do we need? Well, I recommend between 2 to 3 litres per day, depending on how big your body is and how much you train. If you do a lot of intense physical activity or manual labour, you may need more.
