Every asthmatic should be aware that both humidity and cold air are two very common asthma triggers . So why is this? What can you do about it?

<p>Bronchial asthma is a condition caused by chronically hyper-reactive and inflamed airways, punctuated by acute episodes of reversible narrowing of the airways.</p>

Attacks may be mild or severe and may last anywhere from a few minutes to days. The World Health Organization estimates that 235 million people worldwide are affected by asthma.</p>
