8According to a recent study conducted in Loma Linda University, California, laughter is the best medicine to improve memory loss in lder individuals, as it helps reduce the neuron damage caused by "stress hormone" cortisol.
It is well known that too much stress can negatively affect health. It worsens memory and learning ability in elderly individuals, as it increases the production of stress hormone cortisol. Since it is well known that laughter is a stress reliever, the research team led Dr. Gurinder Singh Bains analyzed three separate groups of elderly participants to determine how laughter and humor can boost memory and help improve quality of life.
Their findings clearly showed that the act of laughter - or simply enjoying some humor - increases the release of endorphins and dopamine in the brain and reduces the kevels of cortisol. These neurochemical changes in the brain also increase gamma wave band frequency, which in turn can improve memory.
