There are ways for seniors to protect their health while flying, but it isn't easy these days. The crowds, delays, bad food, lack of sleep, security ordeals and dozens of other anxieties are enough to upset any healthy person, young and old. However, you can fight back and reach your destination in good mood, health and comfort. It won't always be easy, but here are some tips, including frequent catnaps:

1. Bring an adequate supply of regular prescription meds to take at your normal daily schedule. Also have necessary over-the-counter ones, such as allergy, aspirin and anti-diarrhea pills.

2. Carry a basic first aid kit, including Band Aids and a tube of antibacterial ointment. Use them for small cuts or scrapes. Also, to fight recirculated cabin air, dab a bit on your nostrils and around mouth and eyes.

3. There's always concern about flu, so be sure to take your own supply of throw-away wet towelettes, preferably those soaked with alcohol. Wipe hands and face frequently, as well as seat arms and all surfaces you contact in bathrooms and other public places.

4. Get a good night's sleep before flying in the morning. If you're going red eye (after 11 pm), once seated, settle down. Use a coat or blanket, loosen clothing and remove your shoes. A sleep mask keeps out light. Adequate rest, especially when your normal daily routine is interrupted by the stress of travel, is important for maintaining senior health.

5. Eat sensibly and modestly before flying. Heavy meals, especially spiced and high-fat ones, tend to make flying uncomfortable when confined to a narrow seat for hours.

6.Go easy on beer and booze, but drink plenty of bottled water, tea and juices. If cabin air tends to make your mouth and throat dry, take frequent sips.

7. Bring electronic gear that can help keep you calm. Consider a well-filled smartphone for reading, music and video.

8. On long, overseas journeys, every few minutes, stretch arms and legs. Get up once an hour and find a place beyond the passenger area near a bulkhead to do full-body pushing and stretching exercises.
