  • Researchers says that drinking too much water can be fatal

Researchers have presented the findings that drinking too much water during exertion exercises can prove to be fatal compared to the dangers of dehydration

Hydration is given core emphasis and it is often said that dehydration can prove to be damaging for stamina sports by decreasing performance and body stamina. Coaches and athletes around the world take special care to keep themselves hydrated before, during and after the exertion.

"Using the innate thirst mechanism to guide fluid consumption is a strategy that should limit drinking in excess and developing hyponatremia while providing sufficient fluid to prevent excessive dehydration," according to the guidelines, published in the Clinical Journal of Sport Medicine.

Researchers are now saying that drinking too much could be fatal. In a recent research, researchers claim that no more water should be drunk than the thirst requirement. Any athlete should drink as much water as he/ she is thirsty for. Not more.

Their reason is that drinking too much water can lead to imbalance in the sodium levels of the body in the bloodstream by dissolution thus resulting into a condition known as hyponatremia (EAH). The researchers recorded that in 2014 two high school football players lost their lives due to exercise-associated hyponatremia (EAH).

Researchers explain that EAH has major susceptibility rates in endurance competitions such as swimming, military exercises, canoe races triathlons, and marathons. The symptoms of the condition include dizziness, nausea, lightheadedness, puffiness and gaining weight during an event.

In athletes; headache, vomiting, agitation, delirium and confusion are seen, it could be symptoms of severe EAH. The instructions that athletes should drink water until their urine is clear might not be healthy because yellowing actually is an indication that the body salt level is intact.

Tamara Hew-Butler from Oakland University, the lead author of the study expressed that the main goal of the study is to re-educate athletes and everyone about the hazards of drinking beyond thirst.

Dr. James Winger, sports medicine physician at Loyola University Medical Center in a news release said that the risks associated with dehydration are not as hazardous as that of over-hydration. Athletes have rarely died on the field due to dehydration although there have been reports of performance being affected but any athlete can afford to lose 3 to 5 percent of body weight due to dehydration.
