I have wheezing, almost every night, and congestion, so there is difficulty breathing. This happens whether I keep the ac on or just the fan. Even using an air purifier has not helped. The humidity seems to worsen it, because in drier cities this problem does not occur, but when I am back in bombay it does. I have also had asthma since childhood and am using a levolin inhaler to manage it, after a doctor asked me to switch from asthalin.
