How much is enough?

Doing 30 minutes or more of exercise a day for three to five days a week may significantly improve depression symptoms. But smaller amounts of physical activity — as little as 10 to 15 minutes at a time — may make a difference. It may take less time exercising to improve your mood when you do more-vigorous activities, such as running or bicycling.

The mental health benefits of exercise and physical activity may last only if you stick with it over the long term — another good reason to focus on finding activities that you enjoy.

How do I get started — and stay motivated?

Starting and sticking with an exercise routine or regular physical activity can be a challenge. These steps can help:

  • Identify what you enjoy doing. Figure out what type of physical activities you're most likely to do, and think about when and how you'd be most likely to follow through. For instance, would you be more likely to do some gardening in the evening, start your day with a jog, or go for a bike ride or play basketball with your children after school? Do what you enjoy to help you stick with it.
  • Get your mental health provider's support. Talk to your doctor or other mental health provider for guidance and support. Discuss an exercise program or physical activity routine and how it fits into your overall treatment plan.
  • Set reasonable goals. Your mission doesn't have to be walking for an hour five days a week. Think realistically about what you may be able to do and begin gradually. Tailor your plan to your own needs and abilities rather than trying to meet unrealistic guidelines that you're unlikely to meet.
  • Don't think of exercise or physical activity as a chore. If exercise is just another "should" in your life that you don't think you're living up to, you'll associate it with failure. Rather, look at your exercise or physical activity schedule the same way you look at your therapy sessions or medication — as one of the tools to help you get better.
  • Analyze your barriers. Figure out what's stopping you from being physically active or exercising. If you feel self-conscious, for instance, you may want to exercise at home. If you stick to goals better with a partner, find a friend to work out with or who enjoys the same physical activities that you do. If you don't have money to spend on exercise gear, do something that's cost-free, such as regular walking. If you think about what's stopping you from being physically active or exercising, you can probably find an alternative solution.
  • Prepare for setbacks and obstacles. Give yourself credit for every step in the right direction, no matter how small. If you skip exercise one day, that doesn't mean you can't maintain an exercise routine and might as well quit. Just try again the next day. Stick with it.

Do I need to see my doctor?

Check with your doctor before starting a new exercise program to make sure it's safe for you. Talk to your doctor to find out which activities, how much exercise and what intensity level is OK for you. Your doctor will consider any medications you take and your health conditions. He or she may also have helpful advice about getting started and staying motivated.

If you exercise regularly but anxiety or depression symptoms still interfere with your daily living, see your doctor or other mental health provider. Exercise and physical activity are great ways to ease symptoms of anxiety or depression, but they aren't a substitute for psychotherapy or medications.
