The science of exercise and brain health
In a recent study, 454 senior citizens consented to have their brains donated for research after death and completed annual physical checkups and cognitive testing for 20 years. Accelerometers were given to the subjects, which continuously recorded their physical activity and motion.
On tests of memory and thought, those who moved more received higher scores. Additionally, the researchers found that increasing physical activity was linked to a 31% decreased incidence of dementia. Even after taking into account the participants' brain pathology and whether or not they had dementia, the connection between physical exercise and brain function persisted.
In a different study, 160 elderly inactive participants with mild cognitive impairment were given the choice between many activities. They could exercise aerobically (three times).
How your brain benefits from exercise
Dr. Bonner-Jackson asserts that there are numerous possible processes of exercise that might work in concert to enhance brain health. "In general, can stave off decline in certain cases for many years and help people function better, especially in those who are at risk for development of Alzheimer's or other dementias."
Your brain may benefit from physical activity in a variety of ways, each of which helps it maintain memory and perform at its best:
* Fostering cardiovascular wellness. According to Dr. Ross, "What's healthy for the heart is good for the brain."
Reducing inflammation, increasing blood supply to the brain, and reducing stress hormone levels.
Your brain itself may experience physical advantages from exercise. Your cerebral cortex's thickness can increase with exercise.
How much exercise do you need for your brain health?
Here, it's important to concentrate on aerobic exercises. That includes exercises like riding, swimming, dancing, and running. The finest exercises for your brain are those that raise your heart rate.
The majority of people should aim to engage in 15 minutes of strenuous activity three times per week as their primary form of physical activity. Or, Dr. Ross advises, you can aim for 30 minutes of moderate activity five days a week to obtain similar brain-boosting effects if high-intensity workouts don't work for you due to health issues or other factors.

When you exercise at a moderate level, you would be exercising to the point where you could chat but not sing while working out.
