Time to effectsWithout any intervention, the body resynchronizes at roughly one time zone per day, more slowly after eastward flights; with correctly timed, directional light exposure and melatonin, this time can be cut roughly in half, with noticeable improvement in alertness and sleep quality from about day 2-3 after arrival.Subjective improvement in alertness and mood is felt after a single night of good sleep; correlations with lower risk of chronic disease and death observed in cohort studies concern years of consistent sleep patterns.
Who it's forBusiness travelers with important meetings, presentations, or negotiations scheduled right after a transcontinental flightPractically everyone — sleep affects metabolic, cardiovascular, immune, and cognitive health simultaneously
