Runny nose on the hill?

Trail (UK) - - KNOW HOW - Toby Harrison, Ip­swich

QPlease can you tell me why my nose con­stantly runs when I’m hill­walk­ing in the cold? If you al­ways have a stream of snot pour­ing out your nose as you’re strug­gling up a hill­side in the au­tumn and win­ter it’s likely you have coldin­duced rhini­tis. This con­di­tion, aka skier’s nose, is fairly com­mon, and those with asthma, eczema and hay fever may be more likely to ex­pe­ri­ence it.

The ma­jor func­tion of the nose is to warm and hu­mid­ify the air we breathe in, so it does not ir­ri­tate cells when it reaches the lungs. When air is cold and you are in­hal­ing more as you ex­er­cise, your nose has to work harder. Thus the nerves are stim­u­lated to in­crease blood flow to the nose, which warms the in­haled air, while the nasal pas­sage is trig­gered to pro­duce more mu­cus se­cre­tions to mois­ten the incoming air. Cells in the nose also re­act to cold, dry air by pro­duc­ing ex­cess liq­uid. The end re­sult of all this nasal hy­per­ac­tiv­ity? A whole load of snot!

Treat­ment for this non-al­ler­genic rhini­tis usu­ally in­volves tis­sues or a well-ex­e­cuted ‘whale blow’ (plug­ging one nos­tril and blow­ing out the other). Or, you could try a Snot Spot – a soft fab­ric de­vice that fits over a glove and is used to wipe away in­ces­sant cas­cades of mu­cus… Yum!
