Vanity is not the only reason to hit the gym. From heart disease to cancer prevention working out can also help people who get sick feel better.
That may just be the beginning.
The University of North Carolina studied more than a thousand breast cancer patients ages 20 to 54.
Researchers found that five year survival rates were higher among the group that exercised. Breast cancer researcher, Marilie Gammon Ph.d explained, "Physical activity makes you feel better in general. It improves your day to day, how you feel. So, it would be really exciting to find out how that reduces your risk and chances of dying.”
Physical activity may influence breast cancer survival in the same way it affects the odds of developing breast cancer, by reducing hormones that feed tumors and boosting the immune system.
In this study, only women who were overweight or obese reaped the exercise benefits.
Researchers say more work needs to be done to understand the full impact.
