Respiratory problem for newbies in Vietnam

Most likely common culprit is that you are undoubtedly living with air conditioning more often.

On top of that, Vietnamese people including hotel owners and the like are notoriously bad about keeping the filters clean, so mold in the air becomes a problem indoors.

... and may I please say:

When you post in the forum, you are obviously searching for answers.

So it helps to make your topic concise and searchable.

Instead of "Endless crying about life in VN. (small health problem)" you will probably get much better results (responses) if you write the title simply as:

"Respiratory problem for newbies in Vietnam"

Meant as a kind suggestion 🙏

Thanks for your thoughts and posting tips. 

I will try to be more concise than clever on topic titles.

Keep it succinct Danny

AC causes me some chest congestion. Make sure its not set to cold at night. 25 to 27 degrees is ok for me to sleep. Try it see if it helps you

It's easy to blame the air con or climate, but you're in a country where the level of fine particles is crazy.

(these days I check on morning in hcmc with my device : around 150 µg/m3 of PM2.5. I remind the WHO recommends maximum 5 µg/m3)

Although neither a newbie or in Viet Nam, I had the same problem last week. I usually run the A/C for about 20 minutes before going to bed to dry out/cool down my place and then turn it off. Unfortunately, I fell asleep and woke up a couple hours later. It had started raining heavily and the A/C was still running. I turned it off and went back to sleep.

The next morning I felt like I had a slight cold/congestion and felt a little warm. Checked my temperature and it was pretty normal but by evening I had a pretty high fever of 38–39 C (around 100–102 F). I didn't feel particularly bad otherwise so I went to sleep. The next day I felt pretty good but still had the fever, so I thought maybe I had the flu, but my temperature started to go down, eventually becoming normal. Then, I had the chest cold type of cough and phlegm, went to the pharmacy and they gave me bromhexine hydrochloride 8 mg tablets which loosen up the congestion. Gradually, the coughing and phlegm decreased, and has by now basically disappeared. So, yeah, rainy season and A/C use can cause some health problems. If you smoke, that of course is an additional factor.

Based on your previous "time served" in VN, you should probably be considered a Resident Emeritus 😉
