For many, it’s just an inconvenience, but for others, it can completely derail their plans and make a dream vacation or important business trip feel like a marathon of exhaustion. After countless flights, I thought I had jet lag figured out. I’d flown from Los Angeles to London, Toronto to Jordan, and back without breaking a sweat. Then came my return from India.

Jet lag occurs when your internal body clock (aka circadian rhythm) gets out of sync with a new time zone. It affects when you feel awake, alert, or sleepy. Essentially, while your body operates on “home time,” your destination demands a completely different schedule.According to the Mayo Clinic, common symptoms of jet lag include the following: Disturbed sleep (insomnia, frequent waking, or sleeping through alarms) Daytime tiredness Trouble concentrating on tasks or functioning at your usual pace Digestive issues like constipation or diarrhea An overall feeling of malaise or not being well Mood swingsThese symptoms may intensify depending on how many time zones you’ve crossed, the direction of your travel, and your body's adaptability. The Symptoms of Severe Jet Lag Jet lag is often dismissed as simple tiredness, but for some, the symptoms go far beyond that. When I returned from India, I experienced not only sleeplessness but also soreness, nausea, and even disorientation.Additional symptoms that travelers have reported include: Anxiety Headaches or backaches Swollen feet and ankles Ringing in the ears A loss of appetite or feelings of nauseaIt’s a stark reminder that jet lag can manifest differently for everyone. It’s vital to prepare ahead of time, especially for long-haul trips. Proven Jet Lag Prevention Strategies While jet lag isn’t entirely avoidable, you can take steps to minimize its impact.
