Foods that Help You Stay Hydrated

Did you know losing just 10 percent of your bodily water content can cause you to lose your ability to walk? Here are some interesting ways to stay hydrated and healthy.

Water makes up about 60% of our body’s weight. Our body needs water to repair and regenerate cells, and regulate various mechanism in the body, including digestion, temperature, circulation, and detoxification. The need for proper hydration is greater in hot climates, where the body loses water more rapidly through perspiration. Physical activity, altitude, stress, and illness or injury also hasten the loss of water and its need for replacement.


Dangers of Dehydration

When our bodies do not contain sufficient water, we will be dehydrated. In the early stages of dehydration, you will fill feel thirsty and experience dryness in the mouth. As dehydration increases, your blood becomes thicker, making your heart work harder to pump it. Your body also begins to pull water from cells to keep the blood flowing, which increases cellular salt concentrations and damages cell membranes.

Losing up to ten percent of our bodily water content causes headaches, dizziness, and tingling in the limbs. Sufferers may lose the ability to walk and speak clearly. Skin may turn blue, and vision may begin to blur. Loss of 15 percent of bodily water severely impairs vision and hearing, swells the tongue, and makes urination painful. Sufferers may be unable to swallow, or may exhibit signs of delirium. Subsequently, death will usually occur if water is not replenished quickly.

To prevent dehydration and the illnesses it brings, don’t wait to become thirsty before you start drinking. Consuming plenty of fruits and vegetables that are high in water content can also do the trick. A 2009 study by the University of Aberdeen Medical School claims that having watermelon or cucumber after finishing an intense workout may hydrate your body twice as effectively as a glass of water. This is because water-rich fruits and vegetables also provide you with natural sugars, amino acids, mineral salts and vitamins that are lost in exercise.

Here are some natural foods with the highest water content to help you stay hydrated while packing a punch when it comes to nutrients.
