7 of the health risks associated with flying in airplanes

7 угроз для здоровья, связанных с полетами в самолетах

Scientists said what troubles and health problems turn into frequent and lengthy travel.

About what threatens the human frequent airplane travel, said Brazilian scientists from the Federal University of Minas Gerais. Their reasoning on this subject was published by the NCBI.

Gaza. According to experts, during air travel in the pressure inside the plane is maintained at a level corresponding to approximately two thousand meters above sea level. Body many people react to such pressure is the increased concentration of gases dissolved in the liquids. As a result you can feel a tingling in the ears or bloating in the intestine.

Dry skin and cough. Inexperienced travellers don’t know that the plane has low humidity, which threatens to spoil the skin, and cause irritation of the mucous membranes and with them coughing and sneezing.

Swelling of the legs and high risk of blood clots. According to the arguments of scientists, during a flight that lasts more than three hours, there is often swelling of the feet – this, in the first place, contributes to the lack of normal physical activity. Especially dangerous such inactivity for passengers who have problems with the liver, kidneys or cardiovascular system. They forced the aircraft physical inactivity threatens to inflammation of the walls of the veins and an increased risk of blood clots. The people at risk, the scientists suggest during the flight, wear compression stockings.

Pain in the heart and muscles. If a passenger for a long time sitting in one position, is a violation of blood circulation in the blood vessels, which affects blood flow to the heart. All muscles of the body, including the heart, can not tolerate the lack of activity, therefore, can be felt pain.

Viruses. If the cabin of the plane, one passenger suffering from an infectious disease, transmitted by airborne droplets, for others it means a real threat of infection, because people will stay with a sick person in a confined space a lot of time.

Failure of the biological clock. Flights from one time zone to another break the rhythm of the human body. Failure of the biological clock affects the health. Directly it threatens a bad mood and sleeping problems, but can also have far-reaching consequences until the development of cancer.

Hormonal disturbances. Long flights can cause hormonal disorders. It was discovered that in the saliva of flight crew members by one-third higher levels of cortisol. Increased concentration of this hormone is associated with the occurrence of gastric ulcers and other diseases of the gastrointestinal tract, as well as nerve cell damage, memory impairment.
