Name And describe 3 types of sleep disorders - Essay Example

Sleep Disorders There are three types of sleep disorders which are lack of sleep (insomnia), disturbed sleep (sleep apnea, REM sleep behavior disorder, restless leg syndrome and periodic limb movement disorder), and excessive sleep (narcolepsy). The disorders are defined by medical doctors as pathological conditions that interrupt normal sleeping process.Insomnia is one of the most common sleep disorders and is characterized by inability to fall asleep. The reasons for such condition are multiple, including wrong diet, stresses, diseases etc.

The disorder interrupts normal life activity, because people who suffer from it feel constantly tired and depressed about not getting any sleep. Disturbed sleep occurs when there are some factors that constantly make a sleeping person to wake up. For instance, in case with sleep apnea the sufferer can’t sleep because one’s breathing is interrupted; REM sleep disorder is disruptions during the phase of dreams creation in human brain, so it might happen that a person who is dreaming can suddenly wake up and start acting like being in the dream, for example, running or talking etc.

; restless legs syndrome is when a person wakes up because one’s legs start moving. Excessive sleep disorders happen when people have problems with weakness, accidental falling asleep or such disruptions of sleep like sleep paralysis (inability to move the body when waking up or falling asleep) and hypnagogic hallucinations (dream-like hallucinating). Narcolepsy is one of the most serious disorders because people who suffer from it can suddenly fall asleep whatsoever. The last kind of such disorders is cataplexy which is a weakness of the muscles.

The three kinds of sleep disorders are extremely uncomfortable and disturb normal existence.
