Impact of Air Travel on the Human Physiology

The impact of aviation on the human physique: an exploration

Traveling by airplane can be an exciting experience, but it's essential to be aware of the potential health risks and take precautions to ensure a safe and comfortable journey. Here are some key points to consider, based on advice from the National Health Service and the Centers for Disease Control and Prevention (CDC).

Common Health Issues During Air Travel

The most common medical events that occur on airplanes include fainting, nausea, vomiting, respiratory symptoms, seizures, and heart issues. These can be attributed to factors such as cabin air pressure, dehydration, and changes in altitude.

Risk Factors for Blood Clots

Flying can potentially increase the risk of developing blood clots, particularly for certain individuals. These risk factors include being over 40 years of age, obesity, having had surgery or an injury within 3 months, using birth control containing estrogen, pregnancy and the postpartum period, hormone replacement therapy, a history of blood clots, a family history of blood clots, active cancer or recent cancer treatment, limited mobility, and varicose veins.

Dehydration and Jet Lag

Dehydration can occur during air travel due to the dry and lower pressure air inside flight cabins, which can cause water to more quickly evaporate during breathing and from the surface of the skin. People may also drink less during flights than they ordinarily would, and jet lag may lead to disruptions in someone's drinking habits.

Jet lag occurs when someone's usual daily rhythms do not align with a new time zone, causing problems with mood, concentration, and tiredness. It typically arises when traveling across at least three time zones, but it can arise from smaller disruptions.

Preventative Measures

To minimize these risks, the CDC recommends frequent airplane travelers to wear compression stockings and avoid tight clothing around the waist to maintain proper blood flow. It's also important to stay hydrated by drinking plenty of water, to move and stretch during the flight, and to perform regular anti-DVT exercises.

Getting plenty of rest before traveling, changing sleeping routines before flying to reduce the risk of jet lag, and avoiding large meals before traveling can also help. If you have concerns about your health on the trip, it's advisable to speak with a healthcare professional.

Other Health Considerations

Some individuals may be at risk of acquiring a virus through direct contact, so it's recommended to avoid close contact with sick passengers. The CDC advises that individuals with acute or infectious illnesses, such as influenza, delay their travel.

Pregnant women may also face certain restrictions on airplane travel, particularly those who are past 36 weeks' gestation.

While there is no solid evidence that flying causes inflammation, it may exacerbate preexisting chronic conditions. It's important to consult a healthcare professional if you have any concerns about your health and air travel.

In summary, while flying can have various adverse effects on someone's health, illness as a direct result of flying is not common. By taking the necessary precautions and being aware of potential risks, you can ensure a safe and comfortable journey.
