I find this amusing, because I have the same problem when it drops below 30/40deg. However, best thing for the eyes is plenty of eye protection, something a bit oversized is best, a lot even use safety goggles. The sniffles, well, I think thats just something you have to deal with more or less, and is best aleviated by applying the terry cloth patch on the back of your glove to the underside of your nose.
