PSYA01H3 Chapter Notes - Chapter 5: Narcolepsy, Limbic System, Jet Lag
Document Summary
Research shows it is combination of restoration and repair, and preservation and protection. Sleep deprivation: occurs when an individual cannot or does not sleep. The result of sleep deprivation is periods during which the sleep deprivation leads to sleepiness, interspersed with other periods during which individuals feel perfectly normal levels of wakefulness: when sleep deprived: Go through cycles of extreme sleepiness at night with normal levels of wakefulness in the daytime. As the number of days increases, sleepiness increases and cognitive ability decrease. For every hour of deprivation, predictable increases in physical illness, family problems, substance abuse, and academic problems occur. Sleep displacement: occurs when an individual is prevented from sleeping at the normal time although she may be able to sleep earlier or later in the day than usual: jet lag: Is the discomfort that a person feels when sleep cycles are out of synchronization with light and darkness.
