It has been absolutely freezing here in Copenhagen for a couple of weeks now. The weather is beautiful but every time I have been outside - even if only for a few seconds - I just cannot stop freezing afterwards. In these situations I have found that Brazilian music can be an effective cure. So alongside the termostat, you could also turn up the volume with the bossanova of Antonio Carlos Jobin or this funky fella I just found out about the other day: Jorge Ben.
Like a eccentric lost uncle of Devendra Banhart, Ben cooks up an exciting version of samba that makes you completely forget about winter and low temperatures for a while.
