20 Mins of Exercise a Week Keeps Shrink at Bay

Far less clear is how much exercise is best for physical health

(Newser) – If the goal of your exercise program is better mental health, a new study shows that even 20 minutes a week of sports, gardening, or housecleaning may be enough to boost your mood. But if you want to improve your cardiovascular fitness, lose weight, or reduce your risk of life-threatening diseases, figuring out the best amount of exercise becomes much trickier, the New York Times reports.

Recent sport science on the health benefits of exercise is wildly inconsistent: Some studies say exercise in any dose has little effect on risk of disease, depression, and premature death; others say only very rigorous exercise helps; others say even a walk a few times a week reduces the risk of early death. But what scientists do agree on is that the biggest difference is between no exercise and a little exercise: Moderate activity benefits the sedentary more than a stepped-up workout benefits the athletic.

There's another study done recently that found that farmers and people who work outdoors in nature, such as park rengers etc. are less likely to suffer from depression.

SO after much study, debate and tests and hypothesis we are no closer to understanding what the fcuk we were thinking about in the first place. Further grant money will be needed to verify that actually excercising and being productive is healthier then watching msnbc 14 hours a day and eating hoohoo's
