yeah. I posted a link in another part of the thread where he can look up air pollution levels in various cities. That way he can be his decision on data. Plus, I'm not telling him what to do.
in the opening scenes of that video, you can see that the mountains in the distance are grey. That's from air pollution. I've been to many places in Thailand where people claimed the air is good and when I check with an air quality meter, it's usually not.
I would love to find one, though. I did settle in the south, and run an air filter during the worst parts of the year.
I'm not sure the air quality is any better in other SEA countries. Check out aqicn.org and search for your favorite cities, to see what I mean. And historical data will give you a more complete picture.
IMO, there's no place in Thailand with good air. In the south, it's better, but I wouldn't say good. And even there, for a few weeks of the year it's worrying.
Air pollution can cause skin problems or worsen existing allergies. A few people have mentioned shingles. Shingles typically happens on one side of the body, but not the other.
But yeah, go to an actual doctor. I got my medical degree on Google just like everybody else here.
There are increasing levels of air pollution over much of Thailand right now. Get an air filter and run it in your home. Limit time outside and see if it improves.
