The airline industry classifies long-haul flights as those with a flight time of six hours or more. Flying for extended periods can take a toll on our bodies. It can make us tired and uncomfortable, but it can also affect us in the following ways:
- Dehydration– The low levels of humidity in the cabin air can lead to dehydration. Dry recycled air can make our skin and mucosal areas, such as the nose, throat, and mouth, feel excessively dry. It can also lead to a lack of lubrication in our body’s systems. Therefore, it’s important that you drink water before boarding the plane and during your flight.
- Muscle stiffness and soreness – Staying seated for extended periods can lead to muscle stiffness and soreness. A lack of movement can compress joints and reduce blood flow, which further contributes to muscle discomfort. Additionally, dehydration can result in cramps, spasms, or joint pain. To alleviate these issues, stay hydrated and take breaks to walk or stretch whenever possible.
- Airplane ear or barotrauma – Changes in cabin pressure affect the air pressure in your ears, which places stress on your eardrums. This may lead to earaches, muffled hearing, or discomfort. Chewing gum, yawning, or swallowing can usually improve symptoms.
- Gut issues- Sitting for too long can affect our digestive system and trigger stomach issues such as diarrhea, gas, constipation, or bloating. Factors such as cabin pressure, dehydration, changes in eating schedule, and lack of movement can contribute to these problems. Drinking water, walking in the aisles, avoiding certain foods, or taking medication may provide some relief.
- Blood clots /deep vein thrombosis – Long-distance flights increase the risk of blood clots and deep vein thrombosis. Remaining sedentary for hours can lead to blood clots forming in the deep veins of the legs. If these blood clots break off and travel to the lungs, they can cause a serious condition known as pulmonary embolism (PE), which is a blockage in the lungs that can lead to shortness of breath, fainting, or even death. To reduce the risk of complications, long-distance travelers are encouraged to walk around, when possible, move their legs frequently, or wear compression socks.
When flying long distances, it’s crucial to be aware of potential medical issues you may encounter. Pay attention to warning signs and take the proper precautions needed to protect your health.
