Chronic stress is implicated in the development of many diseases. Occupational medicine plays a crucial role in preventing diseases caused by stress and fatigue. We aim to work with researchers from various fields to conduct general research on stress. Our focus is identifying indicators that may lead to disease development, clarifying the mechanisms that cause diseases, preventing diseases in the workplace, and providing recommendations for occupational health-related laws. If you are looking for a comprehensive education in basic and social medicine with a focus on stress, or if you want to specialize in a particular area with stress as the central theme, please get in touch with us.
