• Inactivity shrivels our brains. Our societyseparates the mind and body, but there is a biological relationship between the two.
“Spark” john J.Ratey, MDSource:• Exercise increases levels of serotonin. Lack of this neurotransmitter has been directly linked to depression, which can cause eroded nerve cell connections and shrinkage to the brain.
“Spark” john J.Ratey, MDSource:• 65% of this nations adults are overweight and 17% experience depression sometime in their life to a tune of 26.1 billion dollars in Health Care costs each year!
:“S,park” john J.Ratey, Md AND Source moneyland.time.com• In October 2000, researchers at Duke University put a study in the New York Times that exercise is BETTER than Zoloft for depression. When the top 1/5th controls 84% of all U.S wealth, you can understand why someone in a suit would want you to take a pharmaceutical.
“Spark” john J.Ratey, MDSource:• Science: 80% of brain signaling is carried out by 2 neurotransmitters that balance. Glutamate stirs up activity and GABA clamps down on it. Serotonin, norepinephrine, and dopamine (exercise increases levels of all 3) are neurotransmitters that primarily adjust the flow of info for balance.
“Spark” john J.Ratey, MDSource:• Exercise improves learning on 3 levels:• It optimizes your mindset to improve alertness, attention and motivation.• It prepares and encourages nerve cells to bind to one another, which is the cellular basis for logging in new info.• It stirs the development of new nerve cells from stem cells in the Hippocampus.

“Spark” john J.Ratey, MDSource:• But, high levels of the stress hormone, cortisol, kill neurons in the hippocampus. Reduce stress, while making and keeping new cells: EXERCISE!
Source: “european journal of neuroScience. mar 2011 vol 33. issue 6. p 1018-1024• Voluntary wheel running prominently induces precursor cell proliferation…and neurogenesis at later stages will continue to rise.• Notice it said voluntary? Lab rats have shown that forced exercise doesn’t produce the benefits that voluntary does.
“Spark” john J.Ratey, MDSource:• Antidepressants are effective in reducing depression. Unfortunately, there is known side effects to all of them and it is rewarding for anyone to know that they conquered their depression themselves.• FunFact: Antidepressants were discovered in the 1950’s when people were deemed inappropriately happy after taking an experimental tuberculosis drug.
“Spark” john J.Ratey, MDSource:• What kind of exercise you asked? Workout regimes should include skill acquisition and aerobic exercise.• Hofsta Unniversity study found that ADHD boys from 8-11 participating in martial arts 2 times weekly had an improvement in behavior and performance.
“Spark” john J.Ratey, MDSource:• The attention circuits are jointly regulated by the neurotransmitters norepinephrine and dopamine. These are the chemicals targeted in ADHD medication.• The combination of challenging the brain and body is best in balancing the neurotransmitters and combating ADHD: martial arts, rock climbing, dance, gymnastics and sorry mom, skateboarding are perfect ways!
