Why You Should Wear Sunscreen on a Plane
Briefly

Experts agree that wearing sunscreen while flying is crucial due to significantly heightened UV radiation levels at high altitudes. Dermatologists emphasize that UV rays increase by 2% for every 1,000 feet, leading to an increase of 60-80% at typical cruising altitudes. Prolonged exposure, even during short flights, can contribute to skin damage and higher skin cancer risks, particularly for flight crews. Recommendations highlight the need for adequate sun protection strategies for both passengers and crew during air travel.
Are UV rays stronger on a plane? While any dermatologist will tell you that sunscreen should be worn year-round as UV rays are present regardless of the weather or temperature... given that the average flight is around 30,000 to 40,000 feet in altitude, this is a 60-80% increase in UV radiation levels compared to the ground.
...with repeated skin damage, the signs of skin aging such as hyperpigmentation, sunspots, wrinkles are accelerated.
Wearing sunscreen on your next flight doesn't just apply to passengers but also the flight crew. 'Pilots and flight attendants have a higher risk of skin cancer,' says Dr. Turegano, who points to a 2019 meta-analysis that found these occupations experience twice the risk of melanoma and other skin cancers than the general population.
