Mental health problems are substantially more common in academia than the general population. Younger researchers, including PhD students and early career researchers, experience higher rates of depression and anxiety compared to over 6% of the general public. For academic staff, over 50% show probable signs of depression compared to under 15% of the general population. Key drivers include high workloads, supervisor relationships, career uncertainty, and isolation. Resources are available for individuals, but universities must also prioritize mental health in their culture and policies to improve the situation.
