We're talking temperatures pushing triple digits with heat index values creeping close to 110 degrees. That's the kind of heat that can knock you flat if you're not careful. Whether you're working outside, between air conditioners, or just trying to make it through the day, this isn't the time to try and "tough it out." Heat exhaustion and heat stroke can happen fast, especially for kids, older adults, and anyone with health conditions. Even a few minutes can turn deadly in this kind of heat.
