Hay fever - allergic rhinitis - is a year-round affliction for many New Zealanders, triggered by airborne pollens, especially in spring, but also by dust mites, pet dander and mould. Add the sinusitis sufferers to the sneezers and mouth breathers, and more than 30 percent of Kiwi adults regularly put up with nasal congestion and inflammation, or rely on medications such as antihistamines, nasal sprays and saline rinses.

Promising drug-free relief, Goodair Nosebuds is a breath-powered nasal device, designed to clear congestion naturally - with some innovative tech support. Created by bioengineer David

White at Auckland University of Technology's Bio-design Lab, it harnesses the user's breath to create vibrations that massage the nasal passages and stimulate tiny nose hairs called cilia. These hairs work to sweep mucus, trapped particles and pathogens out of the nasal system - easing the inflammation that leads to congestion and the stuffy feeling. The vibrations, which make a humming sound, also enhance the body's natural release of nitric oxide, a gas that helps open airways and fight infection.

"We've harnessed a natural process - nasal airflow and vibration - and amplified it in a simple, user-driven device," says White. "Rather than medicating symptoms, Nosebuds support the body's own ability to protect and restore itself" Early trials show statistically significant improvements in nasal drainage, airflow and pressure, with users reporting clearer breathing and reduced dependence on antihistamines and steroid sprays. Regular use of the device may also promote better sleep, calmer breathing and even stress relief through enhanced diaphragmatic breathing. Eight years in development, Goodair Nosebuds ($220) are rechargeable and user-friendly; you simply insert and breathe normally through the nose; 20 minutes a day - or two 10-minute bursts
