Is sleep apnea a winter disease? Meteorological and sleep laboratory evidence collected over one decade
Chest, 06/21/2012
Cassol CM et al. – More sleep disordered breathing events were recorded in wintertime than in other seasons. Cosinor analysis uncovered a significant seasonal pattern in the apnea–hypopnea index (AHI) of different patients undergoing polysomnography, independently of gender, age, body mass index, neck circumference, and relative air humidity. This finding suggests that OSA severity may be associated with other seasonal epidemiological phenomena.
