    Strange how 68 seems a cosy temperature to heat to in winter yet a frigid one to cool to in summer. As if the body knows the season.

        @paulg Humidity is a big factor in how much you feel the cold or hot.

        @paulg When you cool air, the resulting air is more humid than heated air.

        @paulg Another possibility is that the air conditioner’s 68 is a lot cooler in the rest of the house away from the thermostat.

        @paulg thermal inertia of the skin. Your skin now is colder then in summer, before you walk in the 68F room.

        @paulg Of course body knows the season, it's programmed to follow 4 seasons cycle and 24 hours day/night cycle. That's why we have jetlags

        @paulg Fanger’s equations for thermal comfort show why; turns out thermostats (even Nest) can't actually regulate temperature comfortably...

        @paulg thermodynamics -> thermal comfort = f(air temp, _radiant_ temp, air motion, humidity, clothing insulation factor)

        @paulg with the uncontrollable central heating by radiators in my apartment I have to open windows to get it down to 72-73. Seems wasteful.

        @paulg and yet here in Moscow shops & offices seem to be heated to 75+! (24C). I can’t stand it! Some serious negotiations with colleagues.

        @paulg Lots of money to be saved if people cooled to 72 or even 74 in the summer, and heated to 68 in the winter.

        @paulg We are not rocks. We generate heat. So feeling is a function of temperature, heat generation and heat loss speed.
