 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 with a 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.
