Jet Lag Disrupts Sleep More After Eastward Trips
Jet lag affects sleep by causing greater disturbances after eastward travel due to challenges in advancing the circadian rhythm, leading to reduced total sleep time and poorer sleep efficiency in the first few nights post-travel.
- Causes more severe sleep disruptions due to phase advance difficulties compared to westward travel.
- Results in reduced total sleep time and poorer efficiency in the initial nights after travel.
