Drinking too much water after a workout or sports activity can lead to Exercise Associated Hyponatremia (EAH), wherein the sodium level of the body decreases during or within 24 hours of physical activity.
This condition is also known as water intoxication. Symptoms of mild EAH include dizziness, nausea and lightheadedness, while symptoms of the severe type include headache, vomiting, confusion or seizure.
Researchers said that the body would not be able to get rid of fluids in the form or sweat or urine, if the person drinks too much. Therefore, the body's sodium level will become diluted, and the cells will swell, which can be fatal, according to Echo Examiner.
EAH happens during marathons, canoe races, swimming, triathlons and other endurance competitions, Eureka Alert reported. It can also happen during military exercises, hiking, football and even yoga.
There is a misconception of drinking too much water to prevent muscle cramps, fatigue and heat stroke.
Dr. James Winger, a sports medicine physician at Loyola University Medical Center, confirmed that muscle cramps and heat strokes happen not because of dehydration. He further explained that a body was producing too much heat, that's why heat stroke occurs.
In the research guidelines published by Dr. Winger, together with Dr. Tamara Hew-Butler of Oakland University, it was revealed that two teenage athletes were diagnosed with hyponatremic encephalopathy. The cause, according to Dr. Mitchell H. Rosner, was an excessive fluid intake.
The research guidelines state that thirst is an enough stimulus for dehydration prevention, Daily Times Gazette has learned. The guidelines are calling out athletes and coaches to be cautious of the fluid intake for hydration before, during and after a physical activity.
The panel is strongly suggesting to educate coaches, athletes, event managers and even sports enthusiasts by widely disseminating the information on the risks of overhydration.
Deaths due to EAH can be prevented by simply listening to the needs of the body, without doing things in excess.
