I've had a cold for the past few days, and when I wake up at least one nostril is totally blocked, and no amount of blowing will unblock it. One side also remains blocked throughout the day, though sometimes the sides switch. However, after about two minutes of cycling (on my way to work, in the gross Beijing air, FWIW), both sides of my nose are unblocked. At this point, I can either breathe fine, or blow my nose (freeing prodigious amounts of gunk) and then breathe fine. I would really love to know why this happens, but can't think of any good reasons, and a cursory googling turns up nothing. tag:ask.metafilter.com,2008:site.93651 Mon, 09 Jun 2008 19:12:25 -0800 bicycle cycling nasalcongestion nose stuffy benign
