They seem simple, but Breathe Right nasal strips have unique engineering that make them a sleeping aid as well as an effective tool for managing nighttime congestion and improving sleep. The nasal strips are made of flexible, spring-like bands that fit right above the flare of the nostrils. The underside is 3M adhesive so that once positioned on the nose, they stay there. As the bands attempt to straighten back to their original shape, they lift the sides of the nose and open the nasal passages. This lifting action helps open inflamed sinus passages and makes it easier to breathe. The nasal strips provide instant relief for congestion due to colds, allergies, or a deviated septum and reduce snoring caused by nighttime nasal congestion.
