Impact of Sleep-Related Products on Human Health

Examines how sleep-related products influence human health by integrating mechanical, thermal and biophysical analyses. Addressing rising prevalence of sleep disturbances and cervical disorders, the study quantifies properties of latex, polyurethane and shape-memory foams. Described are comparative compressive stress–strain responses, thermal conductivities and resilience metrics; evaluated are ergonomic contour, cooling and positional pillows for pain relief, autonomic regulation and apnea reduction. Special attention is given to hypoallergenic encasements for allergen control. The aim focuses on identifying material–geometry combinations that optimize restorative sleep. Methods include comparative analysis of physical measurements, polysomnographic recordings and heart-rate variability indices, supported by critical review of nine key publications. Cagno, Jeon, Lee, Ramli, Li, Park, Boudjemaa, Taheri and Cleveland Clinic sources provided empirical and theoretical foundations. Results reveal superior cervical support from latex contours, thermal stability with gel-infused layers and reduced apneic events through tilt-based designs. Outcomes inform ergonomic guidelines for clinicians and manufacturers to tailor sleep products to individual needs, enhancing nighttime recovery.
