Frequently asked questions
How long does jet lag typically last?
Jet lag generally lasts 1-2 days for each time zone crossed, though eastward travel often takes longer to recover from than westward travel.
Why is eastward travel harder on your body?
Eastward travel is more difficult because it requires advancing your body clock, which goes against your natural circadian rhythm that tends to run slightly longer than 24 hours.
What factors affect jet lag severity?
Jet lag severity depends on the number of time zones crossed, travel direction, departure time, age, individual sleep patterns, and overall health condition.
