Do you know that two thirds of your body is made up of water? Without water we would die. Some estimates say that the average person could die without water in 4 days. We need to drink water every day because we lose it from our bodies in many different ways. We can lose up to 3 litres of water every day through sweating, urinating and even when we breathe.
The body can also produce a litre of water to process, digest and absorb the food we eat. However, body loses more water than it can produce. In some cases it is estimated that the average person could be short of between 1 to 2 litres of water a day.
Water plays an important role in cleansing the body of by products and waste. Water supports the functions of the liver and kidney to rid the body of toxins. If our bodies have a lack of water it can lead to many side affects which you may be familiar with. Lack of water in the body leads to dehydration. Dehydration can cause conditions such as tiredness, headaches, constipation and mental fog.
Water plays an important role in regulating the bodys temperature. A lack of water can make your body hotter which can lower your ability to focus and concentrate. Long term dehydration can also lead to other conditions that can include ulcers and aching joints. It can also increase the levels of allergic reactions such as asthma.
Many people drink water when they feel thirsty. However, the thirst signal is not an accurate indicator because your body is already dehydrated. When you do a lot of physical exercise you also use up a lot more liquid to produce energy and you lose a lot through sweating. During physical activities you should be drinking more water to make up for this loss.
Drinking more water than your body needs can be as unhealthy as drinking too little. Drinking too much water can put added stress and pressure on certain organs such as the liver and the kidneys. In some cases too much water or over hydration can even kill you. Excess water can also wash out too much sodium from our bodies. Sodium is very important to maintain the health and functioning of the body and its organs.
So how much water should we be drinking to maintain a healthily functioning body? It is recommended that we should drink 6 to 8 250 millilitres of fresh clean filtered water per day.
