Taiwan is very humid. When I visit in Canada, my symptoms get better. It's been raining for a week, torrential rains, and again this makes my symptoms a bit worse.
Yet, you cannot reduce it to that factor. As long as you have a weak liver you will HAVE candida. A strong liver will not suffer from damp locations.
You do not need to move out.
You could simply purchase a deshumidifier (is that how you say in English? a machine that takes the humidity away). and put a bit vineagr in the reciptacle that accumulates the water.
