(BlackDoctor.org) — Whether you’re flying to Europe for a much-needed vacation, across the country to visit family or friends, or just travel a lot for business, who wants to waste their trip just adjusting to a new time zone?
Jet lag occurs after air travel across several time zones. It’s caused by the body’s circadian rhythms being out of sync with the local destination time.
Symptoms of jet lag are temporary and include insomnia, irritability, indigestion, and disorientation in the days following air travel.
How long does jet lag normally last? Count on about one day to adjust to each time zone crossed. For example, a flight from New York to London crosses 5 time zones, so it would take roughly 5 days to recover.
Traveling eastward, such as from the United States to Europe or from Europe to Asia, generally causes more severe jet lag than traveling westward.
