circadian rhythm
"But this is what happens sometimes when I don't sleep for 36 hours (no seriously, I've been in 3 time zones in the past few days and my circadian rhythm is like a topless woman riding a unicycle backwards - almost certainly fucked, but unknown by what exactly). So consider this a semi-stream-of-consciousness episode. I was thinking too much and it was keeping me awake, so maybe now I can get some shut-eye. Usually helps when I get it from my head to 'paper'. *fingers crossed* "
"The experts think that circadian rhythms are based on our exposure to light. The circadian rhythm is like a sine wave -- there's a peak and a valley. You can move the peak/valley by as much as 12 hours by varying your exposure to light."
"If a circadian rhythm is like an orchestra - the united expression of the rhythms of millions of cells - a common chemical may serve as the conductor, or at least as the baton."
A good story about the clocks that run our bodies.
