20 Minutes of Moderate Activity May Help Ease Inflammatory Conditions
Moderate physical exercise may have an anti-inflammatory effect on the body — which could be helpful for patients with conditions such as fibromyalgia or rheumatoid arthritis, according to a new study. The study, “Inflammation And Exercise: Inhibition Of Monocytic Intracellular TNF Production By Acute Exercise Via Β2-Adrenergic Activation” — published in the journal Brain, Behavior and Immunity — showed that 20 minutes of moderate exercise stimulates the immune system and promotes better regulation of inflammation. "Each time we exercise, we are truly doing something good for our body on many levels, including at the immune cell level," Suzi Hong, PhD, senior author of the study, said in a news release. "The anti-inflammatory benefits of exercise have been known to researchers, but finding out how that process happens is the key to safely maximizing those benefits." During exercise, the brain activates pathways that speed up the heart and increase blood pressure. Exercise also promotes the production of hormones such as adrenaline. That activates immune cells and reduces  expression of a protein called TNF, which is involved in several inflammatory responses. Researchers analyzed TNF levels in blood samples from 47 healthy volunteers. The blood, drawn before and after 20 minutes of moderate treadmill exercise, showed that was enough to decrease TNF levels by 5%. The exercise intensity level was adjusted based on the participants' fitness levels. "Our study found one session of about 20 minutes of m
