Obstructive sleep apnea is among the most prevalent sleep disorders worldwide, affecting an estimated one billion adults globally when broadly defined and carrying substantial consequences for cardiovascular health, metabolic function, cognitive performance, and quality of life.

Shift work sleep disorder is a circadian rhythm disorder that develops when occupational schedules are persistently misaligned with the individual’s […]

Yet for a growing number of individuals, sustained daytime alertness is not a given but a clinical challenge arising from neurological disorders, disrupted sleep, medical conditions, or the biological consequences […]
