Document Summary

Time frame that takes people to do these things. Best time for physical tasks: suprachiasmatic nucleus. Daylight stimulates the scn, which inhibits production of melatonin in pineal. Photosensitive ganglion cells are stimulated and melanopsin (blue light) is also seen. Darkness removes the inhibition, resulting in more melatonin, therefore we feel tired. Jet lag and shift work: phase advance more difficult than phase delay. Jury is still out, don"t know if it works or is safe. Consciousness: the awareness of the relationship between the self and the external world, monitoring. Tip of the tongue: subconsous level. But may leak out from time to time: freudian slips. A happy person never fantasizes, only an unhappy one. Safety valve: escape from life, alters mood in positive way. Stages of sleep: during sleep, body begins to shut down. Temperature drops: marked decrease in sensitivity to external stimulation.
