We're in the US and don't have it anywhere near as bad for energy costs, but we've turned our thermostat down more than usual this year. It's currently set at 63F(17C) but we've had it a couple of degrees colder. I can't imagine letting it get much lower than that. I'm already wearing sweaters and blankets in the house, and my nose often feels cold. Hopefully that's not so cold we're putting ourselves at risk of some of the health dangers in the article.
