Experts warn of hot car dangers as temperatures near record highs in Colorado

Sasha Gubser, a pediatrician who works in the emergency department at Denver Health [and assistant professor of emergency medicine], echoes McKinley’s warnings. “A kid being in a hot locked car with the windows up or even the windows cracked doesn’t really make much of a difference if the window is cracked compared to all the way up because basically within the first 30 minutes of being inside that vehicle with the doors locked, the temperature will go up extremely quickly,” Gubser said.
