Flying through time, accumulated fatigue, slow recovery\u2026or is your body "silently breaking down"?"},"content":{"rendered":"

Previously, after landing and resting for one night, I was fine. But lately, it takes 2-3 days to feel "my body has recovered." For many people, this might be the point where they start questioning... Pilot health<\/strong> Is the fatigue simply a result of the flight schedule, or are there other factors that should be considered? <\/p>\n\n\n\n

For pilots and crew, advice like "get enough sleep, drink plenty of water" may sound simple, but it's not something you can follow every day in real life. Often, you don't get to choose when you go to sleep, when you wake up, or when your body needs to adjust its sleep schedule again.<\/p>\n\n\n\n

Therefore, if you feel that your body is taking longer to recover lately, the question may not just be: "Have you rested enough?" <\/strong>But it might be. "What has changed to the point that we're not the same person anymore?"<\/strong><\/p>\n\n\n\n

A pilot's health doesn't depend solely on the number of hours they sleep.<\/h2>\n\n\n\n

Our bodies have...""Circadian Rhythm" (biological clock) <\/strong>It helps determine when to wake up, when to be sleepy, and the body's rhythm at different times of the day. However, the daily schedules of pilots and crew members don't always follow this clock.<\/p>\n\n\n\n

Today I might have to wake up at 3 AM. In a few days, I'll switch to a night flight, then fly across multiple time zones, and try to sleep during times when my body still perceives it as daytime. When this happens repeatedly, my scheduled routine might not match my body's perceived time, which is one reason why the term... Getting enough sleep doesn't always mean "fully recovered."<\/strong><\/p>\n<\/div>\n<\/div>\n\n\n\n

Some people may notice difficulty falling asleep, feeling drowsy at unusual times, waking up feeling unrested, or taking several days to return to normal after a flight. These symptoms don't necessarily mean an underlying illness, but if they recur or change from what they usually experience, it's health information that should be taken seriously.<\/p>\n\n\n\n

Why do people feel differently tired even though they're on the same flight schedule?<\/h2>\n\n\n\n

Because fatigue doesn't have a single cause. Besides your circadian rhythm and sleep quality, other factors may be involved, such as stress, nutrition, dehydration, underlying health, or certain health conditions that vary from person to person.<\/p>\n\n\n\n

The low humidity environment in a cabin can cause a dry throat, thirst, or a general feeling of lethargy during and after a flight, but dehydration shouldn't be used to explain all persistent fatigue. The same goes for vitamins and hormones; some people may have these factors involved, while others may not. Therefore, when you start to feel your body recovering slowly, the first thing you should do isn't to rush to find out what's causing it. "What needs to be added?" <\/strong>But it's about gradually understanding that... "What are some factors that might be related to our fatigue?"<\/strong><\/p>\n\n\n\n

Is Vitamin D related to pilots?<\/h2>\n\n\n\n
\n
\n

Even though they spend a lot of time working in the sky, it doesn't mean that pilots and crew members always get enough sunlight to produce enough Vitamin D. Vitamin D plays a role in many aspects of health, including bones, muscles, and the immune system, and low Vitamin D levels may be associated with fatigue in some people.<\/p>\n\n\n\n

But there is one very important point. Feeling tired doesn't necessarily mean you have low vitamin D levels. <\/strong>Because fatigue can stem from a wide range of causes, from sleep problems and anemia to thyroid disorders, nutrition, and other health factors.<\/p>\n<\/div>\n\n\n\n

\n
\"\"<\/a><\/figure>\n<\/div>\n<\/div>\n\n\n\n

Therefore, if you have any concerns about your Vitamin D levels, checking and evaluating them in conjunction with other health information can provide a clearer picture than guessing based on symptoms alone. And you shouldn't start taking high doses of vitamins simply because you feel tired without first assessing the need and appropriateness.<\/p>\n\n\n\n

I'm interested in the Vitamin D testing program.<\/a><\/div>\n<\/div>\n\n\n\n
<\/div>\n\n\n\n

What we should be observing might not be "Are you tired?" but rather "Are you more tired than before?"<\/h2>\n\n\n\n

Fatigue after a long-haul flight can occur. What's more interesting is... Is your recovery pattern changing? <\/strong>Try to think back 6 months or 1 year. <\/p>\n\n\n\n

If your recovery time is taking longer today, even on weekends or after getting enough sleep, and you still feel like your body isn't keeping up, that might be a change you should start noticing.<\/p>\n\n\n\n

If the fatigue recurs, takes longer to recover, or begins to affect concentration, sleep, daily life, or work, it may be helpful to talk to a doctor for further evaluation, especially if other symptoms are present. Do not self-diagnose as just jet lag or try to push through each flight.<\/p>\n\n\n\n

I had a routine health checkup, so why do I still feel like something isn't right?<\/h2>\n\n\n\n

Basic health checkups are important because they help screen for many diseases and risk factors, but results that are within the normal range do not necessarily explain every symptom you are experiencing.<\/p>\n\n\n\n

At the same time, just because you're still feeling tired doesn't mean you need to get every kind of test done. Before deciding what additional tests to get, it might be helpful to look at the bigger picture first.<\/p>\n\n\n\n
