Airports and airplanes are always crowded places with a dry atmosphere and recycled air. Inevitably, they are full of germs, viruses and bacteria, which reproduce rapidly in the warmth. A healthy immune system is the best way to combat germs and sickness, particularly on a long-haul flight.

As well as being in close contact with the general public when flying, going through the necessary scanners also has its own health risk.

Anyone arriving at the airport with a less-than-optimum immune function will inevitably have a high risk of sickness which can ruin any planned vacation, business trip or family visit. Along with packing your bags and securing your home, boosting your immune system should be high on your list of things to do before every trip.


Boost Your Immunity with Vitamin C
Vitamin C is a powerful antioxidant that helps support a healthy immune system as it counters damaging free radicals. Vitamin C is water-soluble so it passes through the body fairly rapidly. However, when taken with a flavonoid such as dihydroquercetin, it is prevented from being broken down and therefore provides protection for a longer period of time.


Get Plenty of Sleep Beforehand
The best way to ensure your immune system is not under stress before you fly is to get plenty of sleep. Avoid any late night social events just before your flight and give yourself 7-8 hours undisturbed sleep to get your immune system in tip-top condition. If you need to get up early to catch your flight, plan to go to bed extra early.


Carry a Hand Sanitizer
Although gels and fluids are limited in hand luggage, travel-size hand sanitizers are well within the 100ml limit. Make sure you put it in a Ziploc bag with other liquids when going through security. It will prove to be a boon. Use it before eating a meal on the plane and after every bathroom visit. Also use it after going through security, where thousands of hands have handled the trays that pass through the x-ray machine.


Load Up with Polyphenols
Airport scanners are now an accepted and necessary part of pre-flight security. However, they do emit low levels of radiation. Frequent flyers such as pilots and business travelers may be concerned about the unknown damage these body scanners are doing.

The best way to protect your body’s cells from radiation exposure is by taking plenty of polyphenols before you fly. Polyphenols are plant-based antioxidants and have been found to protect tissues from ionizing radiation. One of the best and most potent sources of polyphenols is green tea. Try taking Green Tea Elixir, an immune system support.

You should also take resveratrol or quercetin to build up your own radiation protector. In tests, resveratrol was found to prevent radiation toxicity in animals while the antioxidant properties of quercetin have been found to shield mitochondrial DNA from radiation-induced oxidant damage.

Start taking green tea, resveratrol and quercetin a week before flying and throughout your trip. Take extra vitamin C on the day of your flight and use your hand sanitizer frequently from the moment your leave home. Happy travels!
