Answer: Andy’s got it wrong. Your thermostat is usually put in the coldest part of your house, mostly the hallway.  So the hallway will be 17 degrees, but the rest of the house won’t be – as the rest of the house is not controlled by that thermostat. In the summer, the rest of the house will be warmed by outside heat.

Answer: It’s to do with the relative humidity.  The body cools down by sweating and in a humid atmosphere, you’re going to sweat less. It’s less humid in winter, so you will feel colder at the same temperature.
(James O’Brien: You might be right, but Dani didn’t sound like the kind of person who sweats!)
