In honor of the stupidity that is Daylight Savings Time, I’ll write about sleep.

First, this watch seems pretty interesting. It is based on the idea that if you’re never going to get enough hours of sleep a night anyway, then you are best to get a full number of sleep cycles, rather than a fractional one. So it tracks your sleep cycle and wakes you up when you’re most awake.

This reminds me of my general annoyance with the whole concept of sleep and the inefficiency it causes. Sleep has got to be one of the worst vestigial devices still left in humans, although not as bad as the appendix.

Years ago, I came across a blog in which the person was trying out the concept of polyphasic sleep, which is basically napping frequently for short periods each time. The idea was to save total amount of time slept, I guess, or to make sleep more efficient. I guess it worked out well enough to cause a whole bunch of fanatical people to try it.

… is a stupid idea. Yes, daylight is nice to have, but then go to work from 7 to 4 instead of 8 to 5. The only reason to change the clocks instead of changing schedules is because changing schedules (and habits in general) is hard. So we must pretend 7AM is 8AM. In fact, as long as artificial lighting exists, having a non-symmetric waking schedule will always be the norm, I argue. If daylight savings time existed year-round, people would start going to work at 9AM, and end up with no savings of daylight at all. Why don’t I break all my light bulbs and start getting up at 4AM and going to bed at 8PM. That maximizes daylight usage not to mention you see both sunrise and sunset. Sounds good to me. Why doesn’t everybody do that?
