Effects of Exercise On Central Nervous System: Day 2 TFN Challenge

Health can be disrupted significantly with slight shifts in stress response of the brain, causing major frustrations in life. These stressors often lead to disruption in sleep, unhealthy eating habits, and excessive drug or alcohol abuse.

What is chronic stress?

-Chronic stress is the response to emotional pressure suffered for a prolonged period over which an individual perceives he or she has no control. It involves an endocrine system response in which occurs a release of corticosteroids. (Wikipedia)

Chronic stress is considered to cause a wide spread of neurologic conditions such as depression and Alzheimer’s disease. The chronic stress is likely caused by a dysregulation of stress response via the hypothalamic pituitary adrenal axis. Exercise has always been a stress reliever, but in-depth science research hasn’t been available until the past century or so.

Studies of the hippocampus link exercise to cognitive function and memory enhancement. As of late, science has shown that metabolic dysfunction is commonly known to cause Alzheimer’s and depression. Moreover, studies have indicated that central insulin resistance are involved in pathogenesis leading into Alzheimer’s disease.

Here’s What You Can Do!

In a popular Ted Talk, Dr. Wendy Suzuki enthusiastically motivates the listeners in her informative presentation on the effects of exercise on the brain. She talks about her life changing moment that inspired her to shift her research focus on exercise.

“Exercise is the most transformative thing that you can do for your brain today for the following three reasons:” — Wendy Suzuki, Ph. D.

TED Talk The brain-changing benefits of exercise

-It has immediate affects on your brain. A single workout will increase dopamine, serotonin, and neuro adrenal that will increase mood for at least two hours after exercise.

– A single workout will increase focus and attention that will last for at least two hours after exercise.

-Reaction time will improve after exercise.

The effects are long-lasting when exercise is repeated consistently. Exercise changes the brains dynamics when cardio vascular activity is increased, producing brand new brain cells in the hippocampus. This increased function of the brain increases long-term memory according to neuroscience. The increased attention is caused by the immediate response on the prefrontal cortex. The hippocampus and prefrontal cortex are the two brain regions that are most susceptible to neurological diseases, such as Alzheimer’s disease. Exercise isn’t effective to cure these diseases once the person is diagnosed, but they are very useful for strengthening the parts of the brain to prevent neuro diseases.

Neurogenesis is the study of regeneration of new brain cells. Neuroscientist Sandrine Thuret gives a presentation on neurogenesis at a Ted Talks conference. She explains what increases or decreases neurogenesis. The most important part of her presentation comes around 5 minutes where she talks about running and nutritional affects on cell regeneration.

At minimum, everyone should be getting exercise 4–5 days a week for at least 30 minutes. Aerobic exercise is the most beneficial for people who aren’t interested in body building or athletics. Aerobic exercise will increase cardiovascular functions that regenerate new brain cells and burn fat to stay lean.

In conclusion PHYSICAL EXERCISE should be prescribed before pharmaceutical drugs!!

Please show some love, so more people can read this! It would mean a lot to me.
