Shivering is one of those amazing things our bodies do to keep us operating at top speed. It's as if we had an internal thermostat. Too hot, we sweat in order to cool off. Too cold, we shiver to stay warm.
But did you know that as we age the thermostat doesn't always work the way it should? Not good, especially in the kind of weather we've been experiencing lately, and one of the reasons why elderly people are at increased risk of developing hypothermia.
