Dangers of non sedating antihistamine

Rated 4.68/5 based on 577 customer reviews

The hardy nose is a remarkable organ designed to condition inhaled air to protect the delicate internal structures.When breathing through the nose, you may breathe in air at 40 or 100 degrees Fahrenheit, but within a quarter of a second, the air temperature is quickly brought to 98.6.Sometimes cold urticaria is a symptom of another problem, such as cryofibrinogenemia, cryoglobulinemia, or syphilis.Even when it is not, you can develop cold urticaria after receiving a blood transfusion from someone who has it.This allergic response can take several forms, from rashes to wheezing – and then some!

The hives are produced by a rapid release of histamine brought about by Ig E antibodies and eosinophils (a type of white blood cell often involved in allergic reactions) in response to the cold.

Swollen capillaries in the nose are the cause of nasal congestion (nasal congestion is backed-up blood, not increased mucus).

In addition to the congestion, the mucus in the nose, as we’ve said, increases and becomes thicker. Thus cold air, by itself, can produce both nasal congestion and stuffiness.

What exactly are cold alleriges, and what can be done about them?

I was recently diagnosed as having an allergy to the cold, and although the doctor tried to explain it to me, I didn’t fully understand what it is.
