Exercising has many advantages for our health, such as improving blood pressure or reducing the risk of diabetes.
One of the most interesting effects of the sport is the release of the hormone irisin. This hormone seems to be related to anxiety levels. Thus, a greater release of this hormone could help us feel less anxiety.
In addition, the hormone irisin – released during exercise – helps white fat to turn into beige fat, which not only helps protect us from the cold but also helps us lose weight. However, the hormone irisin could play an even more important role, according to research published recently in the journal Nature.
According to this research, irisin could help improve our cognitive ability, which could help slow the progression of Alzheimer’s. This research, conducted in mice, found that both irisin, and FNDC5 – the irisin precursor protein – reduced memory and learning deficits that mice showed.
Not only that, but they found that by blocking the release of irisin, the observed benefits disappeared. By finding this relationship in mice, the researchers looked at the brains of people suffering from Alzheimer’s and people who had a healthy brain. What they observed reinforced the discovery made in mice.
This finding suggests that some medication could be used that increases the production of irisin, thus helping to reduce the symptoms and progression of Alzheimer’s. At the moment, this research is still in the experimental phase with animals. Once this phase is over, they will begin to test with humans whether supplementing with irisin can help people suffering from Alzheimer’s disease in different phases.
In any case, for the moment what we can do is perform physical exercise, regardless of how old we are. Keeping us physically active will not only help us stay physically healthier and age more actively, but it will help us take care of our brain’s health.
