Working longer hours may alter your brain’s structure

(CNN, KYMA/KECY) - Working longer hours might not just be bad for you, they could also be altering the structure of your brain, a new study suggests.

The research found "significant changes" in the brains of people who were overworking, which is a combination of physical and emotional overexertion, as well as a lack of rest.

The research was conducted by two scientists at South Korea's Chung-Ang University and Yonsei University, who followed 110 healthcare workers classified into "overworked" and "non-overworked" groups.

While these behavioral and psychological consequences of overwork are well-known, the underlying neurological mechanisms and changes in anatomy are less understood.
