When you feel thirsty it is a sign that your body is already dehydrated and many bodily functions are already at risk. Most people underestimate how much water should be consumed daily.
The average adult loses about 10 cups of water each day by simply breathing, sweating, urinating and eliminating waste so it does not take long for a water imbalance to occur.
When you consider that blood is made up of 92% water, muscles are 75% water, our brain is 75% water and our bones surprisingly are 22% water you can see why water, or lack of it, affects our entire body.
How is your body affected by the lack of water? The following shows some of the risks:
HIGH BLOOD PRESSURE
In a fully hydrated body the blood is normally about 92% water. When we become dehydrated the blood becomes thicker resulting in higher resistance to free flowing blood and increasing our blood pressure.
If the body is dehydrated it will produce more cholesterol as a means of preventing further water loss from cells.
A lack of water and alkaline minerals including magnesium and calcium can lead to many digestive disorders such as gastritis, ulcers and acid reflux.
JOINT PAIN OR STIFFNESS
The cartilage padding within our joints is mainly composed of water. Therefore dehydration will cause a weakness in the cartilage and natural joint repair is interrupted which results in pain and stiffness.
BLADDER AND KIDNEY PROBLEMS
In a dehydrated body there is a build up of toxins and acid waste as the kidneys are unable to flush these out effectively. This in turn provides an ideal environment for bacteria to thrive and frequent bladder or kidney infections are the result.
When the body is dehydrated the colon is one of the main regions that we draw water from in order to provide sufficient fluids for essential functions around the body. A lack of water intake means that waste moves through the large intestines far more slowly resulting in severe constipation.
ASTHMA AND ALLERGIES
Our bodies will automatically constrict our airways to conserve water if we become dehydrated. Studies have shown that the rate of allergy causing histamines produced within our bodies actually increases exponentially as the body loses more and more water.
Our skin naturally eliminates toxins from within our bodies. However a dehydrated body is unable to perform this efficiently which makes us more vulnerable to many skin disorders including psoriasis, dermatitis, discoloration and premature aging.
When cells are dehydrated within the body they become depleted of energy. This sends signals to the brain which the majority of people confuse with hunger signals. This means we often eat more to restore energy whereas we should in fact simply reach for a glass of water first.
Water is the most important source of energy throughout the body. Dehydration leads to sluggish enzymatic activity which then results in excessive tiredness and fatigue.
Skin is the largest organ of our body. Severe dehydration causes all organs, but especially the skin, to wither and wrinkle prematurely.
The saying goes we should all aim to drink at least eight 8oz glasses of water each and every day. We need even more if we exercise, are ill or are in a hot climate. It is believed that drinking cold water can speed up our metabolism and burn more calories as a result. The effects of an increased metabolism can begin 10 minutes after drinking it and peak approximately 30 minutes later.
A healthy practice to get into is to just sip water throughout the day.
If you are looking to loose weight you should drink two 8oz glasses of water before your meals. This will lead you to cut down on portion size as you are not mixing the thirst and hunger signals and the water will also help you feel full.
Your body needs water to survive.
