20 Minutes Of Exercise Benefits Health
Only 20 minutes of moderate exercise may help improve your health by producing desirable anti-inflammatory effects in your body. This news comes from a University of California, San Diego School of Medicine study showing that 20 minutes on a treadmill led to a five percent decrease in the number of immune system cells that produce TNF, a protein involved in inflammation that can compromise health. Researchers recruited 47 healthy volunteers to walk on a treadmill for 20 minutes at an intensity based on their individual fitness levels. The investigators drew blood from the volunteers before and after their exercise sessions to measure markers of inflammation, which the study team noted were reduced in the participants after their performance on the treadmill. “Each time we exercise, we are truly doing something good for our body on many levels, including at the immune cell level,” noted senior author Suzi Hong, Ph.D. In a press release accompanying publication of the study she said that knowing how exercise can act as an anti-inflammatory may contribute to the development of new treatments for arthritis, fibromyalgia and autoimmune diseases affecting nearly 25 million Americans.
