Why is a smile equal to 10 tonic scales?

A refreshing smile can significantly improve your health and memory, according to a new study.

A recent study has shown that cortisol stress hormones damage certain nerve cells in the brain and can negatively affect memory as well as the ability to learn in older people. Cortisol can contribute to a range of other health problems, including high blood pressure, diabetes and heart disease.

Experts from Loma Linda University (USA) want to find out if a refreshing smile can reverse the negative effects of hormones causing stress. They showed a funny video, which lasted for 20 minutes for a group of healthy adults and a group of elderly people with diabetes.

Volunteers will then complete a memory test to measure their learning, recall and identity. The results will then be compared with the comparison group of older people who are not allowed to watch the comedy.

The researchers also measured cortisol levels in the bodies of all volunteers at the beginning and end of the trial. They found a significant reduction in stress hormone levels in both comedy groups.

Volunteers watching videos also showed significant improvements in all areas of memory tests compared to non-viewing groups. In particular, the diabetic group enjoyed the greatest benefit of changing cortisol levels, while the healthy group made the most progress in the memory test score.

Dr. Lee Berk, a member of the research team, explains: "Everything is very simple, when there is less stress, you will have a better memory. Humor helps reduce stress hormones, Harmful like cortisol, lowering blood pressure, increasing blood circulation and improving mood.Enjoying laughing behavior or simply enjoying some humor increase fake release of endorphins and dopamine, which are associated with cold Satisfaction and pleasure in the brain.

These positive and beneficial neurological changes will then make the immune system function better and even lead to changes in brain wave activity. Specifically, making a happy smile immediately produces the same frequency of brain waves as those who are in deep thought.

The new study once again corroborates folk's experience of "A smile is equal to 10 tonic scales". Due to the refreshing smile that can minimize the damage caused by stress hormones, experts believe it should be used as a treatment.
