RE: New Study Shows Aerobic Exercise Can Improve Cognitive Function
old studies have shown this already. the main part is moderation. overdoing it causes inflammation, which can counter any benefit. it depends on your goals, also.
aerobic exercise increases blood flow, cell proliferation and retention in the brain, and even has been shown to lengthen telomeres, but beware, the person who ran the first marathon, died of it.
Most people don't replenish the vitamins and minerials you sweat out during exercise. Guess what happens when your potassium levels drop to critical levels? Your Heart stops and you drop dead. That's why marathon runners can look so healthy and drop dead in the middle of a race.
sodium, potassium balance is key.
