| Time to effects | Without 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 for | Business travelers with important meetings, presentations, or negotiations scheduled right after a transcontinental flight | Practically everyone — sleep affects metabolic, cardiovascular, immune, and cognitive health simultaneously |
