RE: Steemit Engagement Challenge S5-W1: Laughter is The Best Medicine
Stress can make blood vessels narrow. When blood vessels narrow, blood flow will be disrupted and can cause heart disease, including heart attacks. While laughter can reduce stress hormones, such as cortisol and epinephrine, and increase hormones that can calm the heart.
I also share a post about laughing, if you have time please see it and I am very happy.
