Designed to hold open the nasal passages while you sleep, NasalAid may help you breathe better overnight by providing temporary relief from passing causes of breathing difficulty, like occasional congestion. Opening nasal passages may reduce snoring and lead to a better night’s sleep, too. (And if your sleeping partner is the snorer, maybe a better night’s sleep for you as well.) Because its internal structure is made from thin, spring-tempered steel wire, it can be adjusted to your body: You simply adjust the device for a snug fit by flattening the two free ends in, pop those ends up your nostrils, and breathe easy.
