Dehydration — when the body loses more water than it takes in — can stop the body from carrying out its normal functions. Dehydration can be caused by exercise, diarrhea, vomiting, fever, sweating, heat, alcohol, or caffeine. Keeping the body hydrated can help the heart more easily pump blood through the blood vessels to the muscles, and help the muscles work efficiently, according to the American Heart Association. Anyone can experience dehydration, but the elderly, children and those with chronic illnesses are the most at risk. Most instances of dehydration can be helped by drinking more water, but severe dehydration requires immediate medical attention, according to the Mayo Clinic. Extreme thirst, a lack of urination, shriveled skin, dizziness and confusion are among the symptoms of severe dehydration.
With summer just around the corner, it is more important than ever to stay hydrated. Read on to learn dehydration signs and causes.
