Physical activity not only boosts happiness but is essential for maintaining psychological health. Researchers have pinpointed key brain regions involved, revealing that routine actions like climbing stairs can markedly enhance well-being—especially for those at risk of psychiatric disorders.
While structured exercise is known to improve physical and mental health, the impact of everyday movements—such as stair climbing, walking, or opting for public transport over driving—remains understudied. A collaborative team from the Central Institute of Mental Health (CIMH) in Mannheim, KIT's Institute of Sports and Sports Science, and the GIScience/Geoinformatics Research Group at Heidelberg University examined these common daily activities. "Climbing stairs every day can help us feel more awake and energized, promoting overall well-being," explain lead researchers Dr. Markus Reichert from CIMH and KIT, and Dr. Urs Braun, Head of the Complex Systems Research Group at CIMH's Psychiatry and Psychotherapy Clinic.
These findings are especially timely amid COVID-19 restrictions and approaching winter. "Current limitations on public life and social interactions can harm well-being," notes Professor Heike Tost, Head of the Systems Neuroscience Psychiatry Research Group at CIMH. "Incorporating more stair climbing could make a real difference."
Daily activities sharpen alertness and vitality
In a seven-day ambulatory assessment of 67 participants, everyday physical activity immediately heightened feelings of alertness and energy—core elements of well-being and mental health.
Key brain regions link daily movement to enhanced well-being
Complementing this, MRI scans of 83 participants at CIMH measured gray matter volume to identify involved brain areas. The subgenual cingulate cortex emerged as pivotal, regulating emotions and resilience to psychiatric conditions. This region mediates the connection between physical activity and subjective energy. "Individuals with lower gray matter here, who face higher psychiatric risk, feel less energetic when inactive," explains Professor Tost. "Yet, post-activity, they experience an even greater energy boost than those with more volume."
Targeted everyday exercise for mental health
Professor Andreas Meyer-Lindenberg, CIMH Director and Clinic Medical Director, concludes: "These results highlight how routine physical activity benefits well-being, particularly for those predisposed to psychiatric disorders."
