Jet lag's influence on bowel patterns: An exploration
Jet lag, a common affliction for frequent travelers, is more than just a feeling of fatigue and disorientation. It can also have an impact on our digestive system, causing symptoms such as constipation.
Jet Lag: More Than Just a Feeling of Disorientation
Jet lag, also known as circadian desynchrony, is a circadian rhythm sleep disorder that occurs due to traveling across time zones. This disruption to our internal clock can affect various bodily functions, including the gastrointestinal (GI) tract. Since the GI tract is partly regulated by this circadian system, misalignment can lead to slowed intestinal motility and digestive issues like constipation.
The Role of Circadian Rhythm Disruption
The primary cause of constipation during jet lag is the disruption of the circadian rhythm. This disruption affects the normal timing and function of the digestive system. The body's natural rhythm is thrown off balance, leading to irregular bowel movements.
Other Factors Contributing to Constipation
Several other factors also contribute to constipation during travel. Cortisol dysregulation, or stress hormone imbalance, related to jet lag can impact bowel function and gut microbiome balance, leading to constipation.
Dehydration caused by airplane cabins' low humidity and reduced physical activity during long flights can further exacerbate constipation. Lower cabin pressure can also increase gas expansion, causing bloating and further disturbing comfort and motility.
Changes in eating patterns and gut microbiome shifts during travel add further stress to digestion and bowel regularity. Eating unfamiliar local cuisines or eating more than usual during travel can also lead to indigestion.
Managing Jet Lag and Constipation
To reduce jet lag symptoms, consider consuming smaller meals, avoiding alcohol, and considering caffeine and exercise. Drinking sufficient amounts of water, receiving light exposure, taking melatonin or melatonin-receptor analogs, taking certain prescription sleep medications, using mobile apps that provide advice on managing jet lag symptoms, and eating fiber-rich foods and drinking plenty of fluids can also help relieve constipation.
Before traveling, try adjusting your sleep patterns by going to bed 1-2 hours later if traveling west, or 1-2 hours earlier if traveling east. For west-to-east trips, it may take roughly 1 day to recover for each time zone a person crosses. For east-to-west trips, it can take 1 day for each one-and-a-half time zones a person crosses. Symptoms of jet lag will generally improve after a few days as a person adjusts to the new time zone.
