The “Sneezer Beam” is a two-pronged light-emitting device that, when jammed up your nose to irradiate your nostrils, claims to “inhibit the cells in your nose that release histamine” to cure hay fever and other allergies. It’s £40 from Gizoo.
Searching in the Annals of Allergy, Asthma & Immunology, the “official publication of the American College of Allergy, Asthma, & Immunology” for “light therapy” does not bring up any results, although Gizoo’s write-up says that positive results from a clinical trial of the device were published there. (That doesn’t mean they weren’t, or even that the device doesn’t work, but simply that I can’t find it.) [via Coolest-Gadgets]
