Document Summary

Shift work (inconsistent) - doesn"t change your circadian rhythm, but screws up your health. Lower coordination: disrupt circadian rhythm; constantly fatigued, elevated blood pressure; increased risk of cardiovascular issues, higher level of stress. Sleep disorders: nightmares: persistent negative dreams during rem cycles, night terrors; during non-rem (stage 3/4). Cant recall the dream in most cases: sleep behaviour disorder: can fall out of bed during dreams; don"t get paralyzed like normal people do. Different from sleep walking --> go into wakefulness (between sleep and awake). In rem but have no idea: sleep apnea; fail to breathe during your sleep; not enough oxygen. > make you wake up when there"s a lack of oxygen. Sleep mask; flood you with the type of air you need to keep you going. Constant/undisturbed sleep: sleep paralysis; opposite of sleep behaviour disorder. Sleep paralysis: gaba (inhibitory - prevents motor neurons from firing, cant move), and glycine, occurs during, rem, high stress.
