“From the silly inside jokes we share with friends to the amusement of a live comedy show, laughter is often dismissed as a trivial part of life. However, research suggests that laughter can offer significant health benefits, including reductions in depression, anxiety, and insomnia.

Research also shows that laughter can improve memory. As we age, the chronic release of the stress hormone cortisol can damage the hippocampus—the area of the brain responsible for learning and memory. Studies indicate that laughter reduces cortisol levels, leading to a healthier hippocampus and improved memory, which, in turn, enhances the quality of our lives.”
