Winter is coming and with the cold often comes a snotty nose, but how can you stop your nose from running?

How can I stop a runny nose?

Felicity Bedford was keen to nose the answer so she spoke to GP Adam Forman to find out...

Adam - The nose acts as a very sensitive organ to control the temperature of air and the particles in the air being inhaled. So on a cold day, more blood will be sent to the lining of the nose to warm the air up and this produces mucus, hence the runny nose. Likewise for toxic chemicals or even the chemicals in the hot chili, the same process will happen. The lining of the nose will become injected blood and the lining will produce more mucus and a runny nose. Felicity - OK, so there's not much I can do about cold air and toxins but what happens if I have an allergy like hayfever?

Adam - Then the cells in the lining of the nose will produce a histamine reaction, which causes swelling of the lining of the nose, hence the runny nose. This can be controlled, either by avoiding the allergen or any toxic chemicals but also an allergic reaction can be controlled by a local medical treatment, a nose spray, dampening down the histamine reaction or by taking drugs. Also, you may have a runny nose because you've been crying a lot. The tear ducts in the eye run drain into the nose and hopefully this can be cured quickly with a hug or help from a loved one.

By far the most common cause of a runny nose is a virus, otherwise known as the common cold. And this, unfortunately, has no treatment apart from patience and forbearance and a lot of tissues.

Felicity - Thanks Adam. So, Amanda, if nasal sprays and hugs don't work for you, I guess it's time to go tissue shopping. Next week we'll be journeying into the cosmos to answer Jess' question...
