Doctors believe underlying health conditions rather than cold water alone causes fainting in hot weather.
At their most severe, conditions such as heat exhaustion, dehydration and more can also cause fainting.
People risk developing any of these when the weather gets too hot, and experts agree they are the most likely cause of loss of consciousness.
Emergency room nurse Tenneson Lewis told fact-checking site Snopes, without underlying medical issues, they most likely faint “due to dehydration.”
