One doesn't automatically associate regular exercise with a reduction in the number of colds people get. But researchers from the University of Carolina found that people who exercised regularly were 23% less likely to get colds than those who exercised less. And if those who exercised got colds, the symptoms disappeared more quickly than in the study participants who did little exercise.
Scientists don’t know exactly why exercise changes the structure and function of the brain, but it’s an area of active research. So far, they’ve found that exercise improves blood flow to the brain, feeding the growth of new blood vessels and even new brain cells, thanks to the protein BDNF (brain-derived neurotrophic factor). BDNF triggers the growth of new neurons and helps repair and protect brain cells from degeneration. It may also help people focus, according to recent research.
So short of moving to a blue zone, exercising for just 10 minutes a day, or 75 minutes a week, can earn you an extra 1.8 years. The findings held true even for those individuals who were overweight or obese; adding exercise helped them live longer, while being obese and inactive decreased life span by up to 7.2 years. The benefits of adding more exercise increased and then plateaued at about 300 minutes of weekly exercise (or an hour five days a week) adding an extra 4.2 years of life.

A Penn State University study found that people who exercised, whether it was a mild, moderate or vigorous workout, had more pleasant feelings than those who didn’t. (1)
