This is how you can handle long-haul flight journey
Understanding the Impact of long-duration immobility can help prevent associated health issues
Dubai: Long-haul flights can significantly impact the human body, causing various physiological and psychological effects. From dehydration and jet lag to deep vein thrombosis, understanding these impacts can help travelers mitigate the adverse effects of extended air travel.
Dehydration and dry skin
One of the immediate effects of long-distance flights is dehydration. The low humidity levels inside the aircraft cabin, typically around 20%, can lead to significant water loss from the body. A travel health specialist, Dr. Jane Wilson explains, "The dry cabin air can cause mucous membranes in your nose and throat to dry out, making you more susceptible to infections and leading to dry skin."
Jet lag and circadian rhythms
Jet lag is another common issue, particularly when crossing multiple time zones. It disrupts the body's internal clock, or circadian rhythms, leading to symptoms such as fatigue, insomnia, and irritability.
According to Dr. Michael Breus, a sleep expert, "Jet lag can be minimized by gradually adjusting your sleep schedule to the destination time zone a few days before departure and using light exposure strategically."
Deep vein thrombosis (DVT)
Long periods of immobility during flights can increase the risk of deep vein thrombosis (DVT), where blood clots form in the deep veins, usually in the legs.
Dr. Susan Barnes, a cardiovascular specialist, warns, "Prolonged sitting can slow blood circulation, leading to clot formation. It's important to move around frequently, perform leg exercises, and stay hydrated to reduce this risk."
Reduced oxygen levels
The cabin pressure in airplanes is equivalent to that at an altitude of 6,000-8,000 feet, which means lower oxygen levels. This can lead to hypoxia, a condition of insufficient oxygen reaching the tissues.
Dr. Alan Greene, an aviation medicine expert, notes, "While healthy individuals may only experience mild discomfort, those with respiratory or cardiovascular conditions might face more serious issues. It's advisable to consult with a doctor before flying if you have such conditions."
Psychological effects
Extended time in the confined space of an airplane cabin can also have psychological effects. Anxiety, stress, and even mild depression can occur, especially for those who are anxious about flying.
Dr. Amanda Smith, a psychologist specializing in travel anxiety, suggests, "Engaging in relaxation techniques, staying mentally stimulated with books or movies, and maintaining a positive mindset can help manage these psychological impacts."
Immune system suppression
A long-duration flight can also suppress the immune system due to stress and disrupted sleep patterns. This makes travelers more susceptible to infections.
Dr. Robert Johnston, an immunologist, advises, "Boost your immune system before flying by eating a balanced diet rich in vitamins, getting adequate sleep, and staying hydrated."
Coping strategies
To mitigate these adverse effects, experts recommend several strategies.
Staying hydrated, moving regularly, adjusting sleep schedules before travel, and practicing good hygiene can help alleviate some common issues associated with extended flights.
Moreover, wearing compression socks, using moisturizing skincare products, and carrying noise-canceling headphones are additional measures that can enhance comfort and well-being during extended air travel.
By understanding the impacts of long-haul flights, travelers through proactive steps can protect their health and enjoy a more comfortable journey.
