Sleep apnea drains billions from UK-US productivity every year, study finds

A UCL-led study of 4,000 UK/US adults estimates obstructive sleep apnea costs the US and UK economies more than £137bn ($185bn) annually (US about $180bn; UK about £4.2bn), driven by lost workdays and reduced performance. With around 1 billion people affected globally and up to 85% undiagnosed, researchers call for workplace screening and earlier treatment, noting two-thirds of patients abandon CPAP therapy and that costs may be underestimated as medical and accident costs aren’t included. The study also highlights worker protections and concerns from unions about drivers facing penalties if diagnosed.
