As more of us become more comfortable living with COVID 19, travel plans have exploded. For 2 ½ years many have put air travel for family vacations on hold and we are eager to get back to air travel. As you may have gathered from my previous columns, travel is one of my passions. My family and I have been fortunate to have visited many spiritual places of natural wonder and beauty that we call our National Parks. Many of the parks are on the west coast and require some preparation to endure the many hours of travel by airplane through different time zones. Moreover, travel to other countries and continents, often requiring 8, 10, 16 or more non-stop hours on a plane can really take a toll on your mind and body and gave new meaning to the term “jet lag.”  


According to the Mayo Clinic, jet lag, also known as jet lag disorder, is a sleep disorder that can occur in people who travel through different time zones in a short period of time, such as a flight from New York City to Los Angeles. Obviously, the further the distance traveled and the more time zones entered, the more significant and drastic the symptoms, as found, for example, in those traveling from the United States to Asia.

Sunlight has a direct impact on our internal clock by regulating melatonin, a hormone that regulates sleep and wake cycles in the body. Travel through different time zones can affect the amount and duration of sunlight and therefore, impact the regulation of these cycles. The inability to regulate the cycles results in many symptoms.
