Deep breathing and Stress

When people are anxious before getting surgery, doctors
and nurses often tell them to take slow, deep breaths with

breath-focus of meditation, can induce such calm and
tranquility. In a paper published in Science, researchers
led by Mark Krasnow, a professor of biochemistry at Stanford

effect on the overall activity level of the brain./.../
