Effects of Altitude
The Cabin Environment


Passengers requiring prescription medications should always carry them on board in their hand luggage. This is especially important if you are taking medication for heart disease, diabetes, or seizures. Passengers with severe allergies should carry one or more EpiPens as they would under any other circumstances.

Jet lag is often associated with air travel especially when crossing multiple time zones. The symptoms of jet lag are multiple and vary with each individual, but result mainly from the internal body clock being out of phase with the daily schedule at the travel destination. Sleep is also often disrupted, leading to additional fatigue. Adjusting to jet lag is generally easier when travel is to the west, but most travelers adjust to the new time after a few days. Several tips may help diminish the effects.

  • Rest well before the flight.
  • Try to move 1-2 hours toward the destination time before flight, if your schedule permits.
  • Eat lightly before and during the flight.
  • Once departed, reset watches and other activities to the destination time.
  • Drink water and fruit juices inflight and minimize alcoholic beverages.
  • Consider using caffeinated beverages strategically during the day to mask fatigue but avoid use within 4-6 hours of bedtime when the effect may make sleep onset more difficult.
  • Wear loose, comfortable clothing.
  • Schedule outdoor activities on the first few days at the new destination.
  • After arrival, adjust to destination time as soon as possible.
  • Limit naps to a single nap of 30-40 minutes or less. Go to bed and awaken at the appropriate time for the new time zone.
  • Discuss with your physician if sleep medication could be beneficial.
  • For travelers who SCUBA dive, it is advisable to wait 24 hours after the last dive before taking to the skies so as to minimize the risk of developing decompression illness, such as the bends.
