Exercise protects the brain against depression

Well-conditioned muscles make it easier for the body to purge a harmful protein associated with depression, a new study suggests.

“If you consistently exercise and your muscle is conditioned and adapted to physical exercise, then you acquire the ability to express a class of enzymes that can detoxify chemicals that accumulate during stress and that will be harmful for you,” says senior study author Dr Jorge Ruas of the Karolinska Institutet in Stockholm.

Exercise creates enzymes in the body that breaks down depression-causing proteins. – Filepic
