There are so many benefits to exercise, and every day, we are discovering new ones.A recent Newsweekarticle discussed how exercise can boost brain power and fight off diseases like
Alzheimer’s – more incredible information in an already long list of benefits. new research in animal models
has shown that exercise stimulates a hormone called IgF-I or insulin such as growth factor-I, which, in turn,
goes to the brain to stimulate another brain-derived-neutrotrophic factor (BDnF). BDnF is believed to
facilitate a process in which an animal’s brain nerve cells branch out and communicate with each other.
In fact, research has supported that theory that a brain with lower levels of BDnF is challenged with
retaining new information.How amazing is exercise – not only does it build the body, but the mind as well! Exercise not only slows the
aging process in the brain, but reverses it. Research has also shown that active adults have less inflammation
in the brain and fewer transient ischemic attacks, or ministrokes, which can impair cognition. People who
exercise regularly tend to have higher levels of neurotransmitters that regulate mood, such as serotonin,
dopamine and norepinepherine. With so many people on psychotropic medication, exercise is proving to be
an inexpensive method of maintaining mental health. As with the body’s muscle mass, the same holds true
for the brain: Use it or lose it. Within just a short month of stopping physical activity, the new brain tissue
connections that were formed basically shrink down back to normal.Many parents of children with attention deficit/hyperactivity disorder (ADHD) already know the benefits of
physical activity on their children. It tends to help regulate their moods. An exercise prescription can often
be given in conjunction with medication for these ADHD children/or may even replace a medication regimen.This has broad-ranging implications for children in school and their curriculum. With so many schools
having downsized the number of physical education classes with a focus on more class time, this could
be detrimental. That extra time on the playground may actually boost test scores in all children. The great
thing about introducing physical education at an early age in school is that it sets the tone for future
exercise. Once a healthy habit like exercise is established, it tends to carry on. When people understand
the importance, it becomes even more of a regular routine.So, we know the benefits of exercise for all types of health. not only does exercise help with chronic
conditions, it also promotes wellness.EXERCISE FOR BODY AND MIND
