Document Summary
Consciousness: the subjective experience of the world, resulting from brain activity: altered states: daydreaming, sleeping, meditating, drugs, unconscious processing. You may not have awareness of what you are consciously processing: conscious experience = brain activity. You cycle the stages every ninety minutes. Rem sleep: gets longer as the night goes on, where you do most of your dreaming, slow waves. Immune system: restoring and rebuilding brain tissue, booking immune system. Reliving those memories: sleep= memories, remembering things, remembering learning. Creative thinking: dreams use to be called night hallucinations, the theories of why people dream. Muscles: growth hormones are released and you rebuild muscles, give your body a break. Sleep allows the body to test and repair itself. People with less people are more likely to be over-weight: these people usually want sweet, highly caffeinated items to eat. The evidence: sleep increase after strenuous physical activity, growth hormones secreted in sleep, replenishes the brain. October 4, 2016: strengthens the immune system.
