Everyone experiences stress in one form or another, but the way that it affects each person differs. Some people may need to reduce their stress, and relaxation techniques are one option for doing this.
In stressful episodes, the nervous system is forced into a "fight or flight" response. This response triggers the release of certain chemicals within the body, including adrenaline, norepinephrine, and acetylcholine.
During this release of chemicals, the body is immediately affected by many physical symptoms. These symptoms include an elevated heart rate, increased respiratory rate, blood vessel narrowing, and muscle tightening.
