Just Breathe: Body Has A Built-In Stress Reliever

by Gretchen Cuda

- December 6, 2010

There are plenty of ways to relieve stress -- exercise, a long soak in a hot

bath, or even a massage. But believe it or not, something you're doing right

now, probably without even thinking about it, is a proven stress reliever:

breathing.

As it turns out, deep breathing is not only relaxing, it's been scientifically

proven to affect the heart, the brain, digestion, the immune system -- and maybe

even the expression of genes.

Mladen Golubic, a physician in the Cleveland Clinic's Center for Integrative

Medicine, says that breathing can have a profound impact on our physiology and

our health.

" You can influence asthma; you can influence chronic obstructive pulmonary

disease; you can influence heart failure, " Golubic says. " There are studies that

show that people who practice breathing exercises and have those conditions --

they benefit. "

He's talking about modern science, but these techniques are not new. In India,

breath work called pranayama is a regular part of yoga practice. Yoga

practitioners have used pranayama, which literally means control of the life

force, as a tool for affecting both the mind and body for thousands of years.

Take A Breath

Judi Bar teaches yoga to patients with chronic diseases at the Cleveland Clinic.

Bar uses yoga and modifications of traditional yoga breathing exercises as a way

to help them manage their pain and disease.

" Our breaths will either wake us up or energize us. It will relax us, or it will

just balance us, " Bar says.

She demonstrates a " firebreath. "

" So, at first we pant like a little doggy, and then we close our mouth, and then

the nostril breath starts right after that. OK, here we go, " she says.

Bar then begins to pant, first with an open mouth and then through the nose. It

almost makes you feel lightheaded just watching. Afterward, she says she feels a

little dizzy but energized enough to run around the block a couple of times.

Putting On The Brake

Research has shown that breathing exercises like these can have immediate

effects by altering the pH of the blood, or changing blood pressure.

But more importantly, they can be used as a method to train the body's reaction

to stressful situations and dampen the production of harmful stress hormones.

Esther Sternberg is a physician, author of several books on stress and healing,

and researcher at the National Institute of Mental Health. She says rapid

breathing is controlled by the sympathetic nervous system. It's part of the

" fight or flight " response -- the part activated by stress.

In contrast, slow, deep breathing actually stimulates the opposing

parasympathetic reaction -- the one that calms us down

" The relaxation response is controlled by another set of nerves -- the main

nerve being the Vagus nerve. Think of a car throttling down the highway at 120

miles an hour. That's the stress response, and the Vagus nerve is the brake, "

says Sternberg. " When you are stressed, you have your foot on the gas, pedal to

the floor. When you take slow, deep breaths, that is what is engaging the

brake. "

Changing Gene Expression

Harvard researcher Herbert Benson coined the term " The Relaxation Response " in

1975 with a book of the same name. In it, Benson used scientific research to

show that short periods of meditation, using breathing as a focus, could alter

the body's stress response.

In his new book, Relaxation Revolution, Benson claims his research shows that

breathing can even change the expression of genes. He says that by using your

breath, you can alter the basic activity of your cells with your mind.

" It does away with the whole mind-body separation, " Benson says. " Here you can

use the mind to change the body, and the genes we're changing were the very

genes acting in an opposite fashion when people are under stress. "

Of course, breathing is not the answer to every medical problem. But Benson and

others agree: The breath isn't something Western medicine should blow off. It's

a powerful tool for influencing individual health and well-being. And the best

part is all the ingredients are free and literally right under your nose.
