Almost every time I fly somewhere, I get sick, and it kinda ruins every vacation ever. I’m not sure if it’s the germs on the airplane (causation), or the time zone difference affecting my sleep (correlation). Maybe a combination of both? Last trip, it hit me about 3 days in.
I wouldn’t say my drinking/sleeping habits are that different on vacation compared to my regular life. Is this a common thing people experience, or time to see a doctor?
I desperately wanna enjoy a vacation sickness free and then return to work refreshed instead of sick.


Usually it’s diagnosed with blood work, but the doctor need to ask for the specifics. It’s not rare, like in my case, to diagnose by chance if the symptoms are not severe enough.
If it’s not affecting your daily life you should prioritize what really takes a toll on you, because maybe your immune system is actually working as it should.
Good luck!
