Is Dehydration dangerous?

Dehydration, is defined as the loss of bodily fluids. It occurs when an organism loses more fluids than in takes in.The human body is anywhere from 55% to 78% water depending on age, gender and amount of body fat, and water is essential to human life.

Water forms the basis for all fluids in the body, such as blood and digestive juices, and it's the catalyst in all metabolic functions throughout the body. Water removes toxins and waste products from the body, and it carries nutrients to the cells of the body.

Did you know that by the time you are thirsty you are already dehydrated? Dehydration, as little as a 2% loss in fluid, negatively impacts your body and your mind.

Here are the effects of dehydration at a mild to moderate level:
Fatigue
Muscle weakness
Poor concentration
Headaches
Dizziness or lightheadedness
Decreased metabolism

For athletes or those with physical jobs, the inability to perform and focus as a result of mild dehydration may increase the risk of injury. Athletes and those with physical jobs may suffer a loss of performance of up to 30%. They may experience flushing, low endurance, rapid heart rates, elevated body temperatures, and rapid onset of fatigue. It is imperative that you drink enough fluid before, during, and after your workout or work shift.

Severe dehydration is the loss of 10-15% of body fluids and is a life-threatening condition that requires immediate medical care. The signs and symptoms of severe dehydration include extreme thirst, irritability and confusion, very dry mouth, dry skin and mucous membranes, lack of sweating, little or no urination, any urine that is produced will be dark yellow, sunken eyes, shriveled and dry skin, rapid heartbeat, fever, coma, and even death. Dehydration of any kind will not correct itself.

Many people who suffer from one or more of these ailments have no idea that dehydration is the cause, and that getting relief is as simple as consuming more water. Drinking plenty of water is the best way to stay hydrated because water is processed by the body differently than other types of fluids. It is recommended that you drink the number of ounces in fluid that is equal to half your body weight each day. For example, if you weigh 100 pounds, your hydration goal would be approximately 50 ounces per day with normal activities. You would adjust accordingly for days that you exercise intensely, drinking more.

Most active individuals have some level of dehydration at the end of a workout or work shift. Here is another hydration tip… It is recommended that you drink enough fluids to replace approximately 150% of the weight lost during exercise.

It is important to replace fluids lost when exercising, but drinking pure water exclusively isn't always the safest choice for those who participate in very strenuous or long-duration exercise. When significant amounts of fluid are lost through high-intensity exercise, just replacing water can lead to a chemical imbalance in the body and deficiencies in electrolytes (hyponatremia). Sports drinks, like Gatorade, can help restore electrolytes. These drinks should contain carbohydrates, sodium, and some potassium. The electrolytes in our body include sodium, potassium, chloride, calcium and phosphate, but sodium is the substance of most concern when replacing fluids lost through exercising. Electrolytes are essential for proper organ function. The loss of electrolytes may contribute to dehydration headaches. It is imperative that you take in the proper balance of water and electrolytes, especially during exercise.
