Now that the winter months are upon us getting out of bed in the morning has become more of a chore. The difference in room/duvet temperature is difficult to overcome. It would appear that a room temperature of 18-22 C is recommended for a good nights sleep. I might have a go at putting it to the test.
Current room temperature this evening is 17.37 C and it is cool but not uncomfortable. I will try a small oil filled radiator overnight and see if it maintains a suitable environment. It may cost more to maintain the temperature but I may be rewarded with better sleep. I'm still going to have my socks on in bed just in case.
