Wellness is wearable.

This new jewelry designer is hawking whistle-shaped necklaces that you breathe into, which is supposed to relieve tension, for $85 to $115 each.

The Shift necklace by Komuso jewelry, available in the ever-trendy rose gold ($115), silver ($95), matte slate ($85) and 14-karat gold ($115), is said to promote “a state of stillness in the mind.” The wearer is supposed to breathe in through the nose, and then exhale fully into the necklace’s tube for 10 seconds. You’re encouraged to practice the breathing exercise up to five consecutive times to achieve a Zen state.

“My wife and I are both busy people with busy minds,” Shift necklaces co-founder Todd Steinberg told Moneyish. “We tried to learn meditation to flip unhealthy habits like scrolling and prescription meds into a healthy habit to ease our minds, but quickly gave up because it was proved too difficult to stay consistent.”

So Steinberg and his wife, co-founder Vanessa Steinberg, teamed up with their psychotherapist friend Dr. Daniel Epstein to create the breathing bauble.

The Shift necklace, a $115 accessory said to slow your breath and quiet the mind.

“After five exhales through the Shift; your heart rate lowers, (stress hormone) cortisol decreases, blood pressure comes down, more toxins are released and muscles loosen,” Epstein explained.

Science shows that meditation and breathing deeply can help alleviate stress and improve concentration. Breathing deeply encourages a greater flow of oxygen that can slow the heartbeat and lower or stabilize blood pressure. And other research finds that mindfulness practices like breathing exercises, are shown to measurably alter brain structure, alleviating symptoms of depression and chronic pain.

While you may not need a $115 necklace to breathe more mindfully, the overall wellness trend isn’t a fleeting fad, but rather a lifestyle more and more millennials are aiming — and spending — to attain. The global wellness industry is worth $3.7 trillion, according to data compiled by the Global Wellness Institute. And it’s predicted to grow 17% through 2020. And e-commerce sites like Etsy, Goop, Urban Outfitters and Free People have entire sections devoted to “Wellness” products promising to alleviate stress and promote relaxation.
