Fitness Lowers Depression Risk
A massive study of 7 million people confirms that improvements in cardiorespiratory fitness are linked to lower risks of depression and anxiety [https://nature.com/articles/s41598-026-41932-2]. This reinforces the age-old link between physical and mental health, and the benefits of incorporating fitness into a balanced lifestyle. What type of exercise showed the biggest impact?
While the study doesn't pinpoint a single "best" exercise, previous research indicates that both aerobic and strength training contribute significantly to mental well-being. A combination of both may be more effective than focusing on just one type of fitness. Low cardiorespiratory fitness is increasingly common and has been linked to a higher risk for both depression and anxiety disorders. One study found that individuals with low combined cardiorespiratory fitness and muscle strength had nearly double the odds of experiencing depression. Interestingly, a Swedish study found that when sedentary behavior is considered, the *frequency* of exercise, rather than cardiorespiratory fitness itself, appears to be more directly linked to improved mental health. Exercising just once or twice a week was associated with fewer symptoms of depression and anxiety. Other research suggests a dose-response relationship, where lower cardiorespiratory fitness is associated with a greater risk of mental health disorders. Improving fitness can be a useful strategy for both preventing and treating mental health issues.
