Sleep Disorders

This is a psychological posting on Sleep.
In Psychology lecture lecture I learned about the theories of sleep which is know as an innate biological rhythm that can never be entirely ignored. I also learned about the circadian rhythm, the four stages of sleep and also about dreaming. As humans we have a built-in biological clock that repeats about every 24 hours and it differs depending on each individual. Stage 1 would be the relaxed quiet sleep, Stage 2 would be the quiet, deeper sleep and stage 3 and 4 would be the sleep readying for the REM (Rapid eye movement) sleep which means that the person is dreaming. Even though Stage 3 and 4 are very similar with little difference it is know to be put together as a whole stage. Most of us really enjoy our sleep and also a high majority don't have the time to attain their normal sleep due to their situation or their environment. This might result to sleeping disorders such as insomnia (which means not being able to sleep or waking way too earlier than usual), Sleep apnea (means that the individual stops breathing when sleeping), Narcolepsy (which is the disturbance in the pattern of wakefulness and sleep, individual experiences an uncontrolable urge to fall asleep throughout the day) etc..

All these disorders can be attained through illnesses (can be in terms of genetics) and even through our conditioning that is caused by situations or our environment.

Here is a link to an animated presentation of a sleep lab with a participant and goes through the sleep stages and pattern waves of the brain when the participant is asleep. (https://pantherfile.uwm.edu/johnchay/www/PL06/SL/SL.html)
