Risk factors
By Mayo Clinic staffFactors that increase the likelihood you'll experience jet lag include:
- Number of time zones crossed. The more time zones you cross, the more likely you are to be jet-lagged.
- Flying east. You may find it harder to fly east, when you "lose" time, than to fly west, when you gain it back.
- Being a frequent flyer. Pilots, flight attendants and business travelers are most likely to experience jet lag.
- Being an older adult. Older adults may need more time to recover from jet lag than may younger adults.
Complications
Extreme variations in circadian rhythms have been reported in some instances of heart attacks and strokes, but this is rare.
