Researchers reviewed six studies that looked into the impact of stopping physical activity in people with the mental health condition. They found symptoms like low mood showed up almost immediately.
"It is important that people understand the potential impact on their mental well-being when they suddenly cease regular exercise," study author Professor Bernhard Baune, from the University of Adelaide, told the Daily Mail.
Researchers have found that exercise increases endorphins, which helps boost your mood and help you relax.
According to the report, to maintain health and prevent depression, you need:
* 150 minutes of moderate intensity exercise per week
* Or 75 minutes of vigorous intensity exercise
The study also found no exercise affected women more than men.
