Heat Stroke or Heat Exhaustion?
Particularly warm days, which can arise during the dog days of summer, can be both uncomfortable and unhealthy. Such days also can prove deadly. Despite that threat, the Centers for Disease Control and Prevention notes that heat-related illnesses are preventable. Harmful outcomes also are preventable when people learn to distinguish between heat-related illnesses. Heat stroke and heat exhaustion are easily confused, but the two conditions produce noticeably different symptoms. Recognizing this can help anyone stay healthy or help someone in need this summer.
