When you learn to curb negative thoughts and replace them with positive thinking, you gain more than just a moment's relief from your embarrassment. There's an actual physical change in the body.
"When you repeatedly focus on your trauma, your middle brain responds, which releases cortisol (the stress hormone) into the body, causing a physical stress reaction," Duane T. Bowers, LPC, CCHt, a Washington, D.C.-based therapist told Discovery Fit & Health. On the other hand, if you think about something relaxing, like a great massage you once received, the frontal lobes of your brain will activate and release "feel good" hormones, which cause your body to relax.
Therefore, Bowers recommends this: "Keep a list of positive memories in your pocket. Surround yourself with pictures of wonderful experiences. Play uplifting, positively powerful music to help to you manage where you keep your attention."
