Experts from Loma Linda University suggest that you laugh more older people: laughter, according to the study, retains a clear mind and a good memory to old age.
Cortisol is produced by the body during stress and has a damaging effect not all organs, including the brain. Permanent shocks, the processing result in a protracted depression, reduced memory and learning ability.
Scientists conducted an experiment involving the elderly. The participants were divided into two groups. Some before testing, watched a funny movie, some not. It turned out a positive attitude helped the volunteers from the first group to cope better with the questions. The results of the tests were related to the level of cortisol in the blood. Best questions answered by people with low levels of the hormone.
Experts propose to introduce a "laughter therapy" for older people to improve the quality of life of elderly people and reduce the incidence of depression in this group.
