1. This randomized controlled trial found that children with obstructive sleep apnea syndrome (OSAS) had significantly higher nasal resistance than those without OSAS. 2. However, in participants who were effectively treated with intranasal corticosteroids and oral montelukast, there were improvements in nasal resistance, nasal minimal cross-sectional area, and nasal cavity volume. Evidence Rating Level: 1
Symptom severity is associated with discrepancies between subjective and objective sleep measures in patients with non-seasonal depression 1. This randomized controlled trial found that patients with more severe depressive symptoms exhibited more significant underestimation of total sleep time and discordance between diary-based and actigraphic sleep parameters. 2. However, those who received bright light therapy showed
1. In this systematic review and meta-analysis, patients with obstructive sleep apnea (OSA) had lower 25-hydroxyvitamin D (25-OHD) levels and a higher prevalence of vitamin D deficiency than those without OSA. 2. However, continuous positive airway pressure (CPAP) treatment was not associated with significant changes in serum 25-OHD levels in patients with OSA. Evidence Rating
Physical activity can improve sleep quality and sleep disorder outcomes 1. This systematic review found that all studies reported an association between physical activity and improved sleep quality and reduced severity of sleep disorders. 2. However, physical activity duration, time, and frequency were important. High-intensity physical activity for more than 90 minutes was associated with
1. In this systematic review and meta-analysis, short sleep duration, long sleep duration, and insomnia were associated with higher odds of multimorbidity. 2. There were also associations between multimorbidity and snoring, obstructive sleep apnea, and restless leg syndrome. Evidence Rating Level: 1 (Excellent) It is well known that those who experience sleep problems, including insomnia
