Study reveals how jet lag affects sleep timing and recovery

A collaborative study conducted by researchers at the Centre for Sleep and Cognition at the NUS Yong Loo Lin School of Medicine (NUS Medicine) and ŌURA found that while sleep duration recovers quickly, sleep timing and sleep architecture can take significantly longer to realign when traveling across time zones.

Researchers conducted a comprehensive analysis of sleep during 60,000 trips of over 100km and utilised 1.5 million nights of de-identified data from the Oura Ring to provide the first large-scale, real-world study of jet lag recovery to date. Previous studies on jet lag have either been conducted under controlled laboratory conditions or involved specific groups like athletes or military personnel, whose characteristics may not reflect those of the general traveling public.
