Almost every night when it starts getting late, after 11pm or so, I look at the clock constantly. The dilemma is, sleep or read on, because I’ll inevitably be reading a book.
It’s very cold the last few days, at night it’s below 10ºC. I can hear some people scoffing already, pffft only 10ºC, stop complaining. Consider this: our buildings have no insulation and no heating. Most of us get by with a small fan heater which is okay for heating a small area but nothing more than 10 steps away. Heat leaks out through the walls and the windows. Next time it gets to below 10ºC, turn your heating off and open your windows (to simulate the lack of insulation) for three days and just use a fan heater. See how you get on.
I’ve been wearing socks all day, so my feet are warm. Ease of falling asleep is directly proportional to feet temperature, more specifically temperature at bottom of feet. There’s an old study in Nature:
As we approach the threshold of sleep the body’s temperature regulation system redistributes heat from its core to our extremities. The phenomenon is closely related to the release of hormones such as melatonin, which regulate sleepiness and wakefulness.
Anyway, because of the cold weather, I find that I’m waking up later because it’s nice and warm underneath my duvet. This is a great duvet, even better than the 13.5 tog white goose down one I’ve had forever, this one mm ordered for me at a duvet making place, it’s supposedly handmade and very, very warm. Regardless of when I finally climb into bed, I tend to wake up around the same time. Late.
I’ve always been more of a night owl than a morning person. Luckily I only remember one all-nighter when I was studying, that one time I tried to do what people said to do and drank some coffee which resulted in me getting more sleepy and not liking coffee ever. I don’t exactly find myself getting more energetic as it gets later, it’s just that I find it quieter with few distractions. So I’m up past midnight and I’m reading, or writing a post, or doing something else. Again, there’s a study on this phenomenon which they call delayed sleep-wake phase disorder:
a typical sleep pattern that is “delayed” by two or more hours…Once sleep occurs, the sleep is generally normal. But the delay leads to a pattern of sleep that is later than what is desired or what is considered socially acceptable.
It’s not a disorder, really, is it. Following a different sleeping-hours pattern is not wrong, and people should stop discriminating against others who are simply different. As long as I get my work done, when does it matter what time I did it? Of course it’s easier when I had the freedom of living on my own, and not have to go to work at regular hours. Even people who work at home find it challenging.
Back to my original dilemma. Sleep or read? Let me go read for a little while longer, then I’ll decide.
