ER is more likely to occur when strenuous exercise is performed under high temperatures and humidity. Poor hydration levels before, during, and after strenuous bouts of exercise have also been reported to lead to ER. This condition and its signs and symptoms are not well known amongst the sport and fitness community and because of this it is believed that the incidence is greater but highly underreported. Risks that lead to ER include exercise in hot and humid conditions, improper hydration, inadequate recovery between bouts of exercise, intense physical training, and inadequate fitness levels for beginning high-intensity workouts. Dehydration is one of the biggest factors that can give almost immediate feedback from the body by producing very dark-colored urine.
