Saskatoon's deputy medical health officer is offering a hot tip about the heat.
Simply staying inside to avoid the sun is not good enough, Johnmark Opondo said.
"So, our houses are well-insulated for the winter but, in the summer when it gets really hot, that kind of plays against you," he said.
"Keep hydrated, keep your windows open, fans, fans are good."
Opondo said new research suggests that more people suffer from heat stroke inside their homes than outside. This is especially true with seniors, who are more susceptible to heat-related maladies.
Opondo recommends going outside to beat the heat -- providing you stay in the shade and can catch a breeze.
