I've heard it said that it is best to sleep at 10 deg C or so. It's always
puzzled me because if it's so cold that your extremities feel cold and you
can't get to sleep or you wake up periodically because you're cold, then
you're not exactly getting a good night's sleep. OK, you can use lots of
blankets and duvets, but that still leaves your head uncovered (and I don't
have a lot of hair any more as insulation!) and it's difficult to keep that
covered up without affecting your breathing.

I like to sleep in a room that's at normal room temp (about 20) with just a
duvet. If it's a comfortable temperature during the day, then it's a
comfortable temperature at night with the addition of duvet to make up for
lack of movement meaning the body produces less heat. Why anyone should want
to sleep at a lower temp than that bewilders me.

A very hot night, during a summer heatwave, is no fun: I've sometimes slept
with a desk fan on the bed next to me, wafting me with air to cool me down
(ie increasing evaporation of sweat).


The last house I remember that had problems with ice on the inside of the
windows was my grandparents' Victorian house: single glazed (and with gaps
between the sash and the frame) and no central heating - just coal fires in
the living room and kitchen which died down at night. Childhood memories of
shivering all night, despite loads of blankets and eiderdown; not wanting to
get up in the night for a pee; wrapping blankets round my head, leaving just
my nose and mouth exposed.


I don't normally feel the cold during the day, but I do at night.


My optimum temperature range is a lot narrower than that of a Raspberry Pi
;-)
