If you've got a blocked nose and want a little relief, you might find some with an ice cube. We've mentioned before that a little pressure on the roof of your mouth can do the trick, but redditor rsharvey suggests an ice cube will do even better.

As the post suggests:
My solution is to drink very cold drinks while sucking an ice cube against the roof of my mouth. Blocked noses are caused largely by swollen blood vessels in your nasal cavity, so getting some ice near them will cause them to contract a little. Also I avoid hot drinks. They only make it worse. Which is annoying because a blocked nose is usually joined by a sore throat.
This seems reasonable, but does it work? While I think I still prefer the pressure method because I don't like holding an ice cube in my mouth, it does provide greater relief. It looks like an old trick, too, as a quick search online turns up the suggestion a number of times as well. So if a little pressure from your tongue and you thumb isn't quite doing the trick, break out the ice.
