The page text refers to "A health-related heatwave is a prolonged period of extremely high temperature and humidity for a particular region that exceeds both maximum and minimum thresholds" -- I think this is unclear. The definition given in the documentation refers to daily minima and maxima both exceeding thresholds. Perhaps: "A health-related heatwave is a prolonged period of extremely high temperature and humidity for a particular region during which daily minima and maxima both exceed thresholds"
