How does humming work? Sound moves through the fluid parts of your body 4.5 times faster than through the air, and 12 times faster through your bones (which is why ultrasound imaging works.) Humming vibrates every cell, right down to your DNA. It stimulates production of nitric oxide, which helps maintain cellular health. It strengthens your immune system, improves circulation and digestion, clears your mind, and reduces stress. There is no downside!
In one study, exposure to 50–150 Hz provided relief for 80% of those suffering chronic and acute pain. Other studies show that humming improves hearing and reduces nasal congestion. Humming at 25–150 Hz has been known to speed healing of bone, tendons, ligaments and muscles. 25–50 Hz increases bone density. 100 Hz helps decrease dyspnea and shortness of breath.
So I was curious to see if I can hum in those frequencies. I fired up my frequency measurement app (iStroboSoft) and checked out my humming. At my lowest growl, I hit 130 HZ. Hmmmm. Maybe you guys can do this? The fridge fan was at about 40 HZ though, so maybe there is some benefit to those annoying sounds in our homes?
Humming for happiness--It's as easy as 1-2-3
1.Smile, then breathe in and out through your nose, with your lips closed. As you release your breath, keep your lips closed and gently allow a soft hum to float out. Use a tone that is natural for you, one where you easily feel the vibration in your heart center. Hum softly. Louder is not better.
2. Continue for a few minutes, without straining, until you feel the relaxation response—slower breathing, slower heart rate, calmer thoughts.
3. For maximum happiness and health, hum for at least 20 minutes a day.
Do you feel “humming challenged”? Here’s another option. Cuddle with a cat that loves to purr. Research shows that cats purr at healing sound frequencies of 25–150 Hz. They purr when giving birth, when frightened, and when severely injured. Their bones heal more rapidly after fractures than dogs (who don’t purr, of course). So if you don’t want to hum, you can try some “purr therapy”.
