The importance of Water
Water is one of the most essential elements to your health and also one of the most overlooked. I think we take water for granted, if like me you have never lived in a country where water is a scarce resource then it is very easy to forget the importance of water in our diets. We also live in a society with so many alternatives to well lets face it a rather boring and bland drink.
What we forget is that water makes up two thirds of our body weight and without it we would die.
The human brain is made up of 95% water, blood is 82% and lungs 90%. A mere 2% drop in our body’s water supply can trigger signs of dehydration: fuzzy short-term memory, trouble with basic math, and difficulty focusing on smaller print, such as a computer screen (1)
Mild dehydration during exercise will have a negative impact on your workout, you will loose focus and intensity and will therefore achieve less. Every cell in your body needs water.
Water is important to the mechanics of the human body. The body cannot work without it, just as a car cannot run without gas and oil. In fact, all the cell and organ functions that make up our entire anatomy and physiology depend on water for their functioning. (1)
The functions of water in human body are vital.
- Transports nutrients and oxygen into cells
- Moisturises the air in lungs
- Helps with metabolism
- Protects our vital organs
- Helps our organs to absorb nutrients better
- Regulates body temperature
- Protects and moisturizes our joints (2)
The guidelines of how much water to drink will vary from person to person, depending on gender, height, weight and level of physical activity, but I would aim for 8 glasses a day or 1.5- 2 litres of water per day. Remember often when you feel hungry it is actually due to dehydration. Try drinking a glass of water when you feel hungry, if you are still hungry 30 minutes later then you can eat. Water will aid with digestion so is beneficial to drink before eating, and if it was just dehydration and you are no longer hungry you have saved yourself from ingesting unnecessary calories.
