The world is getting smaller and smaller, more and more people are flying frequently for various reasons. As long as you take a plane, to anywhere is in the twinkling of an eye. At the same time enjoy the convenience; however, many people will feel some discomfort, such as ringing in the ears, muscle aches, jet lag and so on. Medical studies confirm that may indeed lead to some serious health problems in the long-distance flight for a long time sitting in the narrow cabin. However, there is some harm but is too exaggerated. So what you really need to pay attention to often flying, and what hazards, will long-distance flight produce? One pilot once in Qantas Airways said, after breathing contaminated cabin air, the passengers will become very weak. The pilot Susan Mitchell because of health reasons to stop the flight said that she was sick because of long-term exposure to toxic gas on the plane, she said: “This is an important issue for the aviation industry needs to face.” In addition, a spokesman of British Airline Pilots Association told the media, although the majority of pilots think that oil gas leak is a small probability of an accident. However, once it happens, the event would be a disaster for passengers and pilots on the plane. Moreover, Every winter, many people travel by air are concerned, on the plane for several hours and sitting in a closed cabin with hundreds of people, influenza virus and other bacteria will spread over the air to himself. With the rampant avian influenza, as well as a variety of new virus, this worry is got more and more attention. Influenza virus does from person to person through coughing and sneezing spread, however, the study pointed out that such dissemination will occur only in very close contact and patient. Dr. Lahey Clinic in Burlington, Massachusetts, Mark Gendreau said: “when you enter a confined space like the cabin, and the subway, it indeed has the high risk of transmission of the virus, but the plane has a good ventilation system, so which is a relatively safe place.” Besides, more concern is about cosmic radiation. We are usually referring to cosmic radiation is a low-energy photon radiation from the sun and other galaxies; it will lead to human molecules, cells, tissues, structural damage. The atmosphere on Earth can block part of the cosmic radiation, but the cosmic radiation will increase as altitude increases and the longer flight time. So many travelers are worried that the plane will be subject to more cosmic radiation hazards. When Tory was told the secret to get wow gold, RuneScape gold and Tera Gold, he almost cannot believe it. But it is true.
