Heat Stroke vs. Heat Exhaustion: What’s the Difference?


Persons of various ages have varying strengths on how to cope with extreme temperatures, because of the level of development of the central nervous system. Babies and toddlers do not have fully developed central nervous systems, so they may be at risk of developing heat injuries. Persons above the age of 65 experience deterioration in the central nervous system, which makes your body less able to cope with changes in body temperature. Another factor that contributes to the risk for both age groups is that hydration is more difficult. This puts young adults and middle-aged persons at the lowest risk of developing these heat-related injuries.

Heat exhaustion can happen to people of any age, but the possibility of it progressing into a stroke is higher in older persons.
