A study led by a team of international researchers, including those from the universities of Cambridge and Sydney, showed that walking briskly for about 1.25 hours per week could lead to an 18 percent lower risk of depression than no exercise at all. “Most of the benefits are felt when moving from no activity to at least something,” wrote the study authors in a paper published in the journal JAMA Psychiatry. “Our findings have important new implications for health practitioners making lifestyle recommendations, particularly for inactive individuals who may consider the current recommended goal (of exercise) to be unrealistic,” he said.

The team conducted a meta-analysis of 15 studies involving more than 190,000 people to determine how much exercise was needed to reduce depression. The findings showed that “increasing activity amounts to the equivalent of 2.5 hours of brisk walking per week Depression 25 percent less risk. The findings are in line with previous studies, which found that people who exercised had about 43 percent fewer days poorer. mental health.

“Even walking just three times a week gives people better mental health than people who don’t exercise,” study author Adam Checaud, MD, assistant professor of psychiatry at Yale University, told CNN. A 2018 study found that exercising in 45-minute sessions three to five times a week was most beneficial for improving mental health. However, doing household chores also reduced poor mental health days by about 10 percent, the study said.

Another study published in 2020 found that even mild exercise helped protect children from developing depression. The 2020 study showed that 60 minutes of simple activity each day at age 12 was associated with an average 10 percent reduction in depression at age 18. Movement types included running, biking and walking, as well as activities such as working, painting. Or playing an instrument, CNN reported.
