How Does That Work?

The temperature downstairs is 10c(48f)the bedroom is 12c(52f)I have no extra bedding or clothes on compared to other nights(not even the hot water bottle)and I am cosy. Even my hands are not cold outside of the blankets. So why is that? And its been that way all through the night. Thought I would take a reading in my bed and it varies but averages at around 22c(72f)which counteracts the room temperature.

Its a bit of a wet day again but nothing to worry about compared to what parts of the country have had for weeks(floods)and what the experts are saying is to be expected again this weekend.
