Patients with trepopnea in most lung diseases prefer to lie and sleep on the opposite side of the diseased lung, as the gravitation increases perfusion of the lower lung. Increased perfusion in diseased lung would increase shunting and hypoxemia , resulting in worsening shortness of breath when lying on the affected lung.
Other sleep related disorders like sleep apnea are ruled out by examining the patients' respiratory effort, air flow, and oxygen saturation. RMD patients often show no abnormal activity that is directly the result of the disorder in an MRI scan. [7] RMD episodes are strongly associated with stage 2 NREM sleep and, specifically, K Complexes [8].
Sleep deprivation has become hardwired into the military culture. It is prevalent in the entire force and especially severe for servicemembers deployed in high-conflict environments. [188] [189] Sleep deprivation has been used by the military in training programs to prepare personnel for combat experiences when proper sleep schedules are not ...
More than half of people with obstructive sleep apnea have some degree of positional obstructive sleep apnea, meaning that it gets worse when they sleep on their backs. [69] Sleeping on their sides is an effective and cost-effective treatment for positional obstructive sleep apnea.
Dyssomnias are primary disorders of initiating or maintaining sleep or of excessive sleepiness and are characterized by a disturbance in the amount, quality, or timing of sleep. Patients may complain of difficulty getting to sleep or staying asleep, intermittent wakefulness during the night, early morning awakening, or combinations of any of these.
Sleep apnea, obstructive sleep apnea, obstruction of the airway during sleep, causing lack of sufficient deep sleep, often accompanied by snoring. Other forms of sleep apnea are less common. [ 89 ] Obstructive sleep apnea (OSA) is a medical disorder that is caused by repetitive collapse of the upper airway (back of the throat) during sleep.
Common consequences of sleep paralysis include headaches, muscle pains or weakness or paranoia. As the correlation with REM sleep suggests, the paralysis is not complete: use of EOG traces shows that eye movement is still possible during such episodes; however, the individual experiencing sleep paralysis is unable to speak.

Insomnia, also known as sleeplessness, is a sleep disorder where people have trouble sleeping. [1] [11] They may have difficulty falling asleep, or staying asleep for as long as desired.
