A good sense of humor can't cure all ailments, but data is mounting about the positive things laughter can do. 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:
1. 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.
2. Activate and relieve your stress response. A rollicking laugh fires up and then cools down your stress response, and it can increase and then decrease your heart rate and blood pressure. The result? A good, relaxed feeling.
Overall, laughter is good for your health and being positive would lead to positive results.
