How to Beat Jet Lag With an AI Schedule Quiz

Answers and explanations appear as you take the quiz.

1. Which brain region does the guide say coordinates the internal clock that causes jet lag?
   • The hippocampus
   • The cerebellum
   • The suprachiasmatic nucleus
   • The amygdala
2. Without any intervention, roughly how fast does the guide say the body clock shifts after travel?
   • About an hour a day, often less when traveling east
   • About four hours a day
   • It resets fully after one night's sleep
   • It never shifts without medication
3. According to the guide, what does bright light in the hours after your core body temperature low point do?
   • It has no effect on the clock
   • It pushes the clock later
   • It stops the clock completely
   • It pulls the clock earlier
4. When does the core body temperature low point fall for most people, according to the guide?
   • Right at bedtime
   • A couple of hours before their usual wake time
   • At midday
   • Immediately after waking
5. Why does the guide say eastward travel is usually harder?
   • Eastbound flights are always longer
   • Cabin air is drier on eastbound flights
   • It requires shifting the clock earlier, and most people's natural clock runs slightly longer than 24 hours
   • Airlines serve more caffeine on eastbound flights
6. Why does the guide warn against caffeine late in the day when adapting to a new time zone?
   • Its half-life is several hours, so it can disrupt the next night's sleep
   • It blocks the effect of daylight on the eyes
   • It causes the clock to shift in the wrong direction
   • It is banned on most international flights
7. According to the technical section, for which shifts are errors in an AI plan's light windows most likely?
   • Shifts of one or two hours
   • Trips within a single time zone
   • Any flight shorter than four hours
   • Shifts of eight or more hours
8. What does the guide's example suggest for a two-day business trip from Chicago to Paris?
   • Shift fully to Paris time before departing
   • Stay mostly on home time and schedule key meetings in the afternoon
   • Take a double dose of melatonin every night
   • Avoid all daylight during the trip
