Question
Is it true that regular exercise not only protects against obesity, diabetes and heart disease, but additionally against dementia? If so, how does exercise do all of it?
Oh We have a long time of solid evidence that regular exercise protects against all of these items. But how? This has been the query. It's easy enough to see how burning calories with regular exercise will prevent weight gain. However, it’s obscure how exercise can protect against diabetes, cardiovascular problems and mental illness.
Experiments showed that this molecule turns white fat cells (which store fat) into brown fat cells (which burn fat), and in addition improves insulin resistance. Such changes reduce body weight and protect against each diabetes and heart disease. Could Ersin also explain the useful effects of exercise on the brain?
The scientists then used gene therapy to extend ersin levels in mice affected by Alzheimer's-like disease. Mice's cognitive performance improved, as brain changes characteristic of Alzheimer's disease. Studies have identified a technique that irisin may protect the mouse brain from Alzheimer's-like disease: by reducing brain inflammation.
Lessons learned from rodent studies don't all the time apply to humans. Nevertheless, the indisputable fact that humans have the identical molecule of irisin as mice does offers hope that someday the invention of irisin can be useful to human health. More broadly, this study indicates that lots of the various health advantages of standard exercise could also be due, no less than partly, to 1 or more hormones produced by exercise.
