Modulation of the ultradian human nasal cycle by sleep stage and body position.

چکیده
Objective: The nasal cycle, which is present in a significant number of people, is an ultradian side-to-side rhythm of nasal engorgement associated with cyclic autonomic activity. We studied the nasal cycle during REM/non-REM sleep stages and examined the potentially confounding influence of body position on lateralized nasal airflow. Methods: Left- and right-side nasal airflow was measured in six subjects during an eight-hour sleep period using nasal thermistors. Polysomnography was performed. Simultaneously, body positions were monitored using a video camera in conjunction with infrared lighting. Results: Significantly greater airflow occurred through the right nasal chamber (relative to the left) during periods of REM sleep than during periods of non-REM sleep (p<0.001). Both body position (p < 0.001) and sleep stage (p < 0.001) influenced nasal airflow lateralization. Conclusions: This study demonstrates that the lateralization of nasal airflow and sleep stage are related. Some types of asymmetrical somatosensory stimulation can alter this relationship.

Music therapy and sleep cycle
Sleep is a basic behavior in humans. There are some research reports on the cyclical patterns of different types of sleep and their relationship to breathing, heart rate, brain waves, and other physical function. More recently, scientific research has begun to show how music therapy interacts with relaxation and sleep cycle. This research is focusing on the following hypotheses: 1. Music could ...
متن کاملThe Influence of Ultradian Autonomic Rhythms, as Indexed by the Nasal Cycle, on Unilateral Olfactory Thresholds
Cyclic side-to-side variations in the autonomic tone of the nasal mucosae produce corresponding changes in nasal patency. This 90 minute to 4 hour "nasal cycle" is correlated with a number of ultradian rhythms, including asymmetries in left:right cerebral EEG activity and differential performance on visual/spatial psychological tasks (Eccles, 1978; Klein et al., 1986; Werntz et al., 1984). Seve...

BACKGROUND AND OBJECTIVES The phenomena of periodic cycles of vascular engorgement on the nasal cavity mucosa that alternate between right and left sides are termed the "nasal cycle." The physiologic mechanisms underlying this cycle have not been entirely clarified, even more so during sleep. In this study, we measured the periodic patterns of the normal nasal cycle, not only during wakefulness...

Background The most common cause of admission to neonatal intensive care units (NICU) is respiratory distress syndrome. One of the respiratory assistance methods is using nasal continuous positive airway pressure (CPAP). Regarding the importance of pain control which is one of the major priorities in neonatal nursing care, this study aimed to evaluate the effect of body position on pain due to ...
