This week our question comes from Bernetta Starkey, a listener from Elmvale, Ontario. Bernetta emailed us with a question about something a lot of us are thinking about in the summer: heat.

She asks: how does your body generate heat?

To answer this question we reached Dr. Chinthaka (Chris) Heyn, a clinician scientist at Sunnybrook research institute in Toronto.
