I have tried everything. We must keep in mind that there is very little you can do about the outside environment.
Pollens are just too numerous to battle.
You can, however, focus in your home and try to minimize exposure there. If resources are limited, always start in the bedroom. It s here that you spend most of your time and sleep and the better you sleep at night, the better you rest your respiratory system and build up strength for the next day. The quality of your life will improve if you focus first on the bedroom.
