HEALTH RISKS ON FLIGHTS

There are no serious health risks associated with flying; however, certain precautions should be taken to avoid potential health problems.

DVT - Deep Vein Thrombosis

It's only been in recent years that people have become aware of DVT and its effects, due to its publicity. The condition has always been there but because it was less well known people weren't afraid of it.

DVT is caused when movement is restricted and the blood doesn't flow freely through the veins, causing a clot. To avoid DVT it's advised to move around the aircraft for a short walk at frequent intervals. If it's not possible to walk then you should stand and stretch and move your legs and feet. Check the in-flight magazine or video screen to see if there are any recommended exercises.

Medical Conditions

If you have an existing medical condition or have recently suffered a serious illness or had an operation you should check with your doctor that you are fit to fly. You should also check with the airline what their requirements are and whether a doctor's letter is required. You may be feeling fine, but not be within the allowed timescale to fly after an illness or operation. The rules are made to avoid risk to you, other passengers and the crew.

Flying When Pregnant

Providing there have been no serious complications with the pregnancy women can fly at up to 28 weeks pregnant. Between 28 and 36 weeks (32 weeks for multiple pregnancies) a doctor's letter is required stating the mother is fit to fly and there have been no serious problems with the pregnancy. The letter should also confirm the estimated delivery date of the baby.

Ear Problems

Try to avoid flying with an ear infection, cold or sinus problems as these can be exacerbated with cabin pressure. If you do feel your ears hurting try sucking a sweet or holding your nose and blowing.

Food and Drink

It is advised to avoid drinking alcohol on flights as it dehydrates and can make you feel very sluggish. Try and drink water and soft drinks to keep yourself fresh and alert.

Heavy meals should be avoided as they will also make you feel uncomfortable. It's much better to eat frequent light snacks.

Stress

Stress, often caused by fear of flying can affect your health during a flight. Even though it may seem tempting to help you get through the journey try and avoid alcohol or sleeping tablets. Instead, if you really dislike flying you could ask your doctor for a light tranquilliser.

It's also worth reading one of the many fear of flying websites or books available. If your case is really extreme you could consider taking a 'Fear of Flying' course that most of the major airlines offer. Above all, try not to think about your fear and remember; planes don't just fall out of the sky for no reason.
