Document Summary
Responsible for lab, lecture & book (book isn"t comprehensive) Consciousness is a terrible curse: i think, i feel, i suffer . Occurs when alone, relaxed, engaged, in a boring/routine task, about to fall asleep. Arousal, metabolism, heart rate, body temp: high point is afternoon, low point is night. Affects long distance air travel (jet lag: worse with eastward travel (to europe) More likely to eat, have sex, and other pleasurable things in morning. Morning people are generally introverts, most night people are extroverts: women are more likely morning people, men are more likely night people. Natural body clock is longer than 24 hours; if left without time pieces or other points of reference (sun) it is naturally 25 hours. Human clock is contextual based on sun and clocks. Ny disc jockey peter tripp (1959) went 200 hours without sleep. Circadian rhythms adaptively prevent long periods of sleeplessness. Humans are relatively long sleepers: adults. 7-9hrs/night: elephants 2hrs/night, lions and bats 20hrs/night.
