Electrolyte supplements popular with endurance runners can't be relied on to keep essential sodium levels in balance, according to researchers at the Stanford University School of Medicine and their collaborators.

Rather, longer training distances, lower body mass and avoidance of overhydration were shown to be more important factors in preventing illness caused by electrolyte imbalances, the researchers found. Their study also showed that hot weather increased the rates of these types of illnesses.
