Stress relief comes from laughter, according to the Mayo Clinic —
Here is what the Mayo Clinic staff report states: A good sense of humor can’t cure all ailments, but data are mounting about the positive things laughter can do.
Short-term benefits
A good laugh has great short-term effects. When you start to laugh, it doesn’t just lighten your load mentally, it actually induces physical changes in your body. Laughter can:
Stimulate many organs. Laughter enhances your intake of oxygen-rich air, stimulates your heart, lungs and muscles, and increases the endorphins that are released by your brain.
Activate and relieve your stress response. A rollicking laugh fires up and then cools down your stress response and increases your heart rate and blood pressure. The result? A good, relaxed feeling.
Soothe tension. Laughter can also stimulate circulation and aid muscle relaxation, both of which help reduce some of the physical symptoms of stress.
Long-term effects
Laughter isn’t just a quick pick-me-up, though. It’s also good for you over the long haul. Laughter may improve your immune system too among others things
