One of the problems that people tend to run into from time to time whenever they are flying is the fact that many of them end up getting sick after they come off the airplane.
  There are a number of different reasons why this occurs, anywhere from them having a low tolerance and being unable to fend off any bacteria or viruses that are loose on the plane to simply getting sick because of the differences in air pressures that occur while you're on the plane.
One of the best things that you can possibly do in order to prepare yourself for flight if you tend to get sick after you fly is to build up your immune system ahead of time.
  It is not necessary for you to do something for the long term in order for this to happen, as many of us are perfectly fine whenever we do not have to fly on a plane.
  Building up your immune system is a relatively easy thing to do, and some people enjoy it so much that they stick with the regime for quite a while, even if they are not flying.
The first thing that you need to do is to modify your diet so that you are eating plenty of raw fruits and vegetables.
  These are really going to be the building blocks that helped to boost your immunity and help you to be healthy, overall.
  One of my favorite ways of getting these fruits and vegetables is by having a green smoothie every day.
  Take two of your favorite fruits and put them in a blender, along with 12 ounces of water, half a dozen ice cubes and a large handful of green, leafy vegetables.
  Blend until smooth and enjoy.
Another thing that is necessary in order for you to build up your immune system for flight is to get some exercise, especially if you're not currently exercising at all.
  If you're not used to exercising, it can be as slight as taking a walk around the block but if you are exercising, you might want to kick it up a notch for a week or so ahead of the flight in order to really build your body up and get it ready.
It does take a little bit of advance preparation, but the health benefits that you're going to receive and the fact that you can avoid sickness while you're flying will make it well worth the effort.
