Traveling remains one of life’s greatest joys, but the body at 70+ doesn’t respond the same way it did at 50. What was once an exciting adventure can, without proper planning, turn into a chain of medical risks, medication imbalances, and unexpected expenses.
This article isn’t meant to scare you; it’s meant to empower you to make informed decisions and take care of your health. Always consult your trusted doctor.
6 Reasons to Avoid Long Trips If You’re Over 70
1) Deep Vein Thrombosis (Blood Clots Due to Immobility)
What happens: Sitting for 6–12 hours reduces venous return in the legs, thickens the blood due to dehydration, and promotes clots that can travel to the lungs (embolism).
Warning signs: pain or heaviness in the calves, unilateral swelling, localized heat.
How to reduce the risk: Stay hydrated, walk every 60–90 minutes, wear graduated compression stockings, choose an aisle seat, and ask if you need prophylaxis if you are taking anticoagulants or have a history of heart disease.
2) Cardiopulmonary stress due to altitude, cabin pressure, and extreme climates
What happens: Pressurized cabins are equivalent to an altitude of 1,800–2,400 meters; there is less oxygen per breath. Heat/humidity or extreme cold require rapid adjustments from the heart and lungs.

Warning signs: Unusual shortness of breath, chest tightness, dizziness, palpitations, swollen ankles.
How to reduce the risk: Choose destinations with temperate climates, take shorter trips, use a portable pulse oximeter if you have COPD/heart failure, and plan with your cardiologist or pulmonologist before long flights.
3) More severe infections due to immunosenescence
What happens: With age, the immune system responds more slowly; New pathogens, air conditioning, and local water sources increase the risk of respiratory or gastrointestinal illnesses.
Warning signs: persistent fever, diarrhea with dehydration, worsening cough.
How to reduce the risk: up-to-date vaccinations (influenza, pneumococcal, COVID-19, as indicated), strict hygiene guidelines, bottled water, and choosing accommodations with good ventilation and cleanliness.
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.
