Remarkably studies have shown that humming for an hour a day can eliminate sinus troubles in just 4 days! The theory is that some non-allergic sinusitis is actually caused by a fungus – the Mayo Clinic found 96% of patients had fungi in the nasal mucus and an immune reaction to it in nasal tissues. It’s thought that the humming works by stimulating the natural production of nitric oxide, which is a natural anti-fungal and it kills it! Well, that’s a new one on me. That said, really useful – if I can’t find an allergic answer to this common problem, I will now be treating it anti-fungally – and musically! (WDDTY April 08)
