In addition to making your tongue hurt, capsaicin can also help unblock your sinuses. While this is not a good fix if you’re having trouble breathing (please see a doctor if this is the case!), a spicy pepper can help open things up and relieve congestion. The peppers keep your mucous thin, and as a result, lower your chances of a sinus infection. While there’s some evidence that suggests chili pepper sprays help your stuffy nose, don’t go buying a bunch of chilis just yet: Most evidence is largely anecdotal, and some spicy foods can actually aggravate sinusitis.
