Holiday Chaos Can Trigger “Internal Jet Lag,” Doctors Warn

As the holiday season ramps up, many are bracing for the usual stress, late-night parties, and shifts in their regular schedules. But doctors are warning that these festive disruptions can lead to a surprising consequence: “internal jet lag.”

Unlike the jet lag experienced after crossing time zones, internal jet lag arises from irregular sleep patterns, even without travel. The late nights, coupled with holiday stress and changes to routine, can throw off the body’s natural circadian rhythm – its internal clock that regulates sleep-wake cycles, hormone production, and other vital functions.

“People often think of jet lag as something you only get from flying, but disrupting your sleep patterns, even at home, can have a similar effect,” explains [Let’s add a fictitious expert here] Dr. Emily Carter, a sleep specialist at the National Sleep Institute. “The holiday season, with its increased social events and pressure, is a prime time for these disruptions.”

The consequences of internal jet lag can extend beyond simple fatigue. Disrupted circadian rhythms have been linked to mood swings, digestive issues, and even an increased risk of heart problems. “When your body is constantly trying to adjust, it puts a strain on various systems,” Dr. Carter adds.

Experts recommend trying to maintain a consistent sleep schedule as much as possible during the holidays, even on weekends. Prioritizing relaxation techniques like meditation or deep breathing can also help mitigate stress and promote better sleep. And while holiday treats are tempting, maintaining a balanced diet and avoiding excessive alcohol consumption can also contribute to a healthier sleep pattern and a smoother holiday season.
