Getting 150 minutes of moderate exercise per week may be as effective as antidepressants for treating mild to moderate depression, according to some clinical studies.

Here’s something most people don’t hear enough: some clinical studies have found that exercise and standard antidepressant treatments performed similarly for mild to moderate depression. That’s not a fitness blogger’s opinion — it’s a conclusion that has appeared in peer-reviewed medical research. The amount that keeps showing up in studies? Around 150 minutes of moderate-intensity exercise per week.

That breaks down to about 30 minutes, five days a week — things like a brisk walk, a bike ride, shooting hoops, or dancing. You don’t have to be an athlete. Research found that people who did roughly 150 minutes of moderate exercise per week had about a 25% lower risk of developing depression compared to people who were totally sedentary. Even half that amount — around 75 minutes a week — was linked to an 18% lower risk. So even a little movement can make a real difference when it comes to protecting your mental health.

The research also points out something worth knowing: the biggest benefit tends to go to people who go from doing nothing to doing something. You don’t need to run marathons. Just getting off the couch and moving your body regularly is where most of the mental health payoff happens. One study specifically found that 150 minutes per week appeared to be an optimal dose for depressed patients.

Mayo Clinic backs this up too — exercise and physical activity can genuinely lessen anxiety and help improve mood. It’s important to know that this isn’t a replacement for professional care, especially for moderate or severe depression. But for many people dealing with mild symptoms or everyday stress, regular movement is a real, accessible tool that can make a meaningful difference. If you’re going through a rough stretch mentally, getting your body moving isn’t just a nice idea — it may be one of the most powerful things you can actually do about it.
