Exercise Is Associated With Improved Mental Health

Individuals who exercise regularly have been found to report 1.5 fewer days of poor mental health per month, as published in the journal Lancet Psychiatry.

The largest known study of its kind included 1.2 million people, showing team sports, gym workouts, cycling, and aerobics were associated with the most benefits. Exercising for 45 minutes 3-5 times per week was associated with the greatest decreases in poor mental health. Exercise was not always beneficial as exercising for more than 3 hours a day was associated with increased risk of poor mental health; and was noted that people who exercise excessively may have obsessive tendencies that may increase risks.

Data was used for 1.2 million people that completed the Behavioural Risk Factor Surveillance System surveys in 2011, 2013, and again in 2015. Participants reported how many days they classed their mental health as not good, and how often they performed exercises outside of work.

After adjusting for factors such as income, marital status, race, age, BMI, previous diagnosis of depression, education level, and employment status the average number of days reported as being of poor mental health was 3.4 in 30 days, with participants who exercised reporting 3.4 fewer days of poor mental health; and the largest decrease in numbers of poor mental health days was seen among participants with previous depression diagnosis.
