Mitochondria Connect Stress, Brain Function, and Mental Health

A scientific review suggests that mitochondria, the energy-producing structures in cells, play a key role in translating psychological stress and loneliness into physical health outcomes, with chronic stress impairing mitochondrial function and contributing to diseases like depression and cardiovascular issues. The review highlights the importance of mitochondrial health in resilience and potential interventions such as exercise to improve cellular and mental well-being.
