A recent study conducted in The United States of America has revealed doing more than 45 minutes of physical exercise for three to five times a week may not be beneficial to one’s health on the long run.
The study that further suggested less than an hour of physical exercise can reduce poor mental health studied activity levels of 1.2 million people for a month and rated their mental health.
British Broadcasting Corporation (BBC) reported that the study discovered people who exercised had 1.5 fewer bad days in a month compared with people who don’t exercise at all.
The researchers said all physical activities are capable of improving mental health irrespective of age, gender or type of activity.
The researchers, however, could not conclude physical activities were the cause of improved mental health.
A previous research in this line had thrown up mixed results while some other studies suggested a lack of physical activities could lead to poor mental health.
According to the authors, the new study proved that exercise was already known to reduce the risk of heart disease, stroke, and diabetes.
Exercise had larger effects on people who were previously diagnosed with depression
Dr Adam Chekroud, But one of the study author who is also an assistant professor of psychiatry at Yale University, USA, warned that there could be such a thing as doing too much exercise.
“Previously, people have believed that the more exercise you do, the better your mental health, but our study suggests that this is not the case,” he said.
