Humidity control is necessary for rhinitis.

I thought I had a cold and kept neglecting it, but unexpectedly I found out it was allergic rhinitis.

Runny nose, sneezing, and nasal congestion...

When I take medication while attending the hospital, the problem gets resolved, but after some time, it starts again and doesn't improve.

I am diligently disinfecting the skin and always paying attention to keep the indoor environment dry.

When I turn on the heating in winter, it gets drier, so I think using a humidifier helps a bit.
