Psychiatry. Rhythmic movement disorder ( RMD) is a neurological disorder characterized by repetitive movements of large muscle groups immediately before and during sleep often involving the head and neck. It was independently described first in 1905 by Zappert as jactatio capitis nocturna and by Cruchet as rhythmie du sommeil. [ 1]
Trepopnea /tɹɛpəʊpˈniːə/ is dyspnea (shortness of breath) that is sensed while lying on one side but not on the other [ 1] (lateral recumbent position). It results from disease of one lung, one major bronchus, or chronic congestive heart failure that affects only a side of breathing. Patients with trepopnea in most lung diseases prefer ...
Benign paroxysmal positional vertigo ( BPPV) is a disorder arising from a problem in the inner ear. [ 3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [ 1] This can occur with turning in bed or changing position. [ 3]

[ 5] Snoring, which may be (but is not necessarily) an indicator of obstructive sleep apnea, may also be alleviated by sleeping on one's side. [ 6][ 7]
Positional asphyxia. The knee-on-stomach position compresses the chest, making it difficult for the person on the bottom to breathe. Positional asphyxia, also known as postural asphyxia, is a form of asphyxia which occurs when someone's position prevents the person from breathing adequately. People may die from positional asphyxia accidentally ...
Rapid eye movement behavior disorder occurs when there is a loss of normal voluntary muscle atonia during REM sleep resulting in motor behavior in response to dream content. It can be caused by adverse reactions to certain drugs or during drug withdrawal; however, it is most often associated with the elderly and in those with neurodegenerative ...
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
