 Hi, this is Lifestyle. I'm Peter McArthur. We have another heat wave at hand with heat advisories in place. WDEL's Mike Phillips talked to the doctor from ChristianaCare about all of the phases of heat illness. Dr. Bradley Sandella, Medical Director of ChristianaCare Center for Virtual Health and is also a sports medicine physician. What are the stages of heat-related illness and the symptoms that come along with each? Yeah, it's a great question.
