I have been miserable for a good few weeks now, owing to the severe lack of daylight. This has not been helped by the fact my sleep patterns have completely inverted and I have been falling asleep around 7 am (!) and mostly unable to get out of bed before 5 pm (!!). The problem is that having Delayed Sleep Phase Syndrome, the usual techniques for restoring a normal sleep-wake cycle don't work. ( Read more...Collapse )
Through application of SCIENCE to the problem, I've discovered that it's not just my sleep-wake cycle but other circadian rhythms that get messed up. The reason why I can't wake up too much earlier is because my body temperature is too low. Usually, it's spot on 37.0 °C while I'm awake, but “too early” it can be as low as 36.3 °C. Okay, that doesn't sound like much of a difference – but we are homiothermic and our body temperature does only vary within a degree or so. If I am ill and have a mild fever of only 37.5°C, my brain feels “fried” and it takes serious effort for me to think. Clearly my brain is highly sensitive to temperature changes.
I need to get a) a lamp so I can have the abnormally bright “blue” lightbulb above my eyes in the mornings without it also being the main light source in the bedroom (as it bothered EVERYONE else who came to the house while it was installed, and is way too stimulating for me at night time), and b) some yellow ski goggles (research has shown that people with DSPS and bipolar II may be oversensitive to blue light, so should wear yellow filters when watching TV or using a computer in the evenings to avoid the light keeping them awake). This requires a) motivation and b) going into a ski shop. I'm not sure how this is to be achieved, considering that motivation requires... oooh, getting enough sleep and hours of sunlight.
