The chances of a plane crashing are about one in 5.4 million, according to statistics from The Economist, and actually dying from a plane crash is one in 11 million. To put this into perspective, you have more chance of being struck by lightning or being attacked and killed by a shark.Nevertheless, there are still many people who are terrified of flying and dread traveling anywhere by plane in case of turbulence, wheels squeaking, being in a crowded space or skidding on landing – and of course, crashing.A fear of flying is also known as aviophobia and usually manifests itself in symptoms like panic, breathlessness, shallow breathing and a racing mind. It’s possible that aviophobia can develop from a bad experience but it can also be borne without a known cause.Aside from going to the doctor to get some medication support or a referral to a psychological service, there are some simple things you can try to combat your fear of flying. Below are nutrition and lifestyle tips to help you conquer that panicked feeling as the plane pushes back.Photo by Getty/martin-dmFoods that might helpSalmonSalmon contains vitamin D and omega-3 fatty acids which may help regulate the chemical messengers – neurotransmitters – our brain releases which can calm and relax the mind.

Alcohol changes the levels of the chemical messengers in the brain making you more anxious when it wears off.CaffeineIt’s bad news for coffee lovers who have anxiety. Caffeine is a stimulate and stimulates the same fight or flight response that the fear of a plane crashing does. If you overdo caffeine before a flight it can trigger a panic attack so either switch to decaf or avoid for a few days before your flight.SmokingLike alcohol, smoking may give you the immediate feeling of calm but this is temporary as the underlying issue isn’t solved. Additionally, the effect of smoking before you check in to calm your nerves will wear off by the time you board. You’ll then have to deal with the cravings and withdrawal symptoms as well as your fear of flying.Photo by Getty/Hoxton/Tom Merton)Some lifestyle tipsMeditationPractice meditation for 10 minutes per day every week before your flight and in the morning before.Get plenty of ‘good’ sleepTry your best to get your sleep hygiene right as this may play a role in your mood and anxiety.
