4) Medication chaos when crossing time zones
What happens: Adherence to schedules is critical for medications such as anticoagulants, insulin, antihypertensives, or thyroid medications. Changing time zones causes omissions or duplicate doses.
Risks: bleeding or thrombosis due to incorrectly dosed anticoagulants; hypo/hyperglycemia; thyroid decompensation.
How to reduce the risk: a written schedule adjustment plan validated by your doctor, a pill organizer with alarms, medication always in carry-on luggage, and translated digital prescriptions.
5) More Falls and Confusion in Unfamiliar Environments
What happens: Unfamiliar hotels and streets (lighting, steps, slippery floors) + jet lag = tripling the risk of falls. The extra cognitive effort reduces attention.
How to reduce the risk: Stay on the ground floor or use an elevator, grab bars in the bathroom, wear non-slip shoes, ensure a clear route to the bathroom at night, and use a cane or walker if you already use one.
