Supplements that aid memory
Humor and laughter can help combat memory loss in the elderly, is that it suggests a new international study.
Previous research has found that cortisol, the stress hormone, can damage the memory and learning in older people. This new study examined whether humor can reduce the damage caused by cortisol.
Researchers have shown a funny video of 20 minutes to a group of healthy elderly and a group of elderly people with diabetes. These groups were compared with a group of seniors who have not seen the video. The two groups who watched the funny video showed a significant decrease in cortisol levels and greater improvements in memory tests, compared to the group who has not seen the video. The diabetes group showed the largest decrease in cortisol levels, while the healthy group had the greatest improvement in memory tests.
The study was presented at the Experimental Biology meeting in San Diego.
"It 's simple: less stress you have, the better your memory works," says one of the authors of the study, Lee Berk, the Federation of American Societies for Experimental Biology in a press release. "Humor reduces stress hormones like cortisol, which decreases, lowers blood pressure and increases blood flow, and improves the mood. The act of laughing causes the release of endorphins and dopamine in the brain, which provides a sense of pleasure and reward. these neurochemical changes and positive benefits, in turn, make better the function of the immune system, "said Berk. "There are also changes in brain wave activity to what is called the 'wave band range', which amplify the memory and the memory. So laughter is proving to be not just a good medicine, but also a memory enhancer , promoting the quality of our lives "
