Sensitive to the Rain?

Its strange, since the rainy season started in Nov/Dec last year, I have been sneezing or having runny nose on a daily basis. It normally starts flowing on the way to work in the morning, continue dripping in the afternoon, and usually stops when I reach home. Unless it is raining.

On and off, I would be wondering... could it be the rain that is causing my frequent runny nose? Could it be sinusitis? After all, I do have a sensitive nose. Perhaps my sensitive nose is aggravated by the rainy weather? But what's wrong with water droplets falling from the sky? Could it becoz of the carbonic acid in the rain? Or dust particles from factories or forest fires that is falling onto the ground? It shouldn't be the rain itself becoz I shelter myself with an umbrella, except that 50% of my working pants gets totally soaked while walking in the rain. Maybe its becoz of the change in surrounding temperature? So am I really ill from germs or just sensitive to the rain? What exactly is it about the rain?

This evening, my answer became much clearer. I had just woken up from a nap from 6 - 8pm and walked out to the hall to eat my dinner. Then, my nose was fine. But just a few minutes into my dinner, I started to sneeze, followed by runny nose (again). I was surprised coz I didn't have any runny nose for the entire day! Why suddenly start dripping again for no reason?

The answer came in within a minute. The rain started to pour, making that usual beating sound when it hits the concrete ground. Aha! It is the rain! But could it really be? Well, my nose continued to flow throughout my dinner, causing me to walk to and fro to blow out the mucus from my nostrils. Then suddenly I could no longer hear rain drops hitting the ground. Yup, the rain has stopped. And soon after, my nose just stopped dripping! Eh? Sure or not? It is really the rain? Or because I took Chlorpheniramine (medicine for runny nose) when my sneezing was ongoing and uncomfortable at the early start of the rain?

Hmm... well... I would have to continue to observe to confirm my findings...
