Does exercise help anxiety?
Yes, modestly. Across many trials, regular exercise reduced anxiety symptoms by a small to moderate amount. The benefit is clearest for anxiety symptoms in general; for diagnosed anxiety disorders such as GAD and panic disorder the evidence is weaker, and NICE's main treatments are CBT-based self-help, CBT or applied relaxation, and medicines. Exercise works well alongside them.
What is the best exercise for anxiety?
Most types help. Recent analyses rank strength training and mind-body exercise such as yoga and tai chi highly, and walking, running and cycling also help. In the largest trial, a mix of cardio and strength circuits three times a week worked. Choose something you enjoy and can repeat, and add strength training twice a week.
Does exercise help anxiety straight away? How long does it take?
A little straight away: one session lowers anxiety by a small amount for a while afterwards, which is why a walk can take the edge off. Lasting change comes from exercising regularly: trials showed benefits after 2 to 12 weeks, and fear of body sensations fell within 2 weeks in one trial. Give a regular routine about 12 weeks, and see your GP sooner if anxiety is getting worse.
Can exercise cause panic attacks? Why do I feel anxious after exercise?
Exercise makes your heart race and your breathing speed up, and if you are sensitive to those feelings they can feel like the start of panic. In a lab study of people with panic disorder, exercise raised these body sensations but not anxiety, and fewer people had a drug-provoked panic attack after exercise than after rest. In small trials, the fear of these sensations faded with repeated exercise, faster with harder sessions. Caffeine and pre-workout drinks can add to it. See a GP if you keep getting symptoms, and get urgent help for chest pain, fainting or palpitations that don't settle.
How can I tell a panic attack from a heart problem when I exercise?
You can't always tell, and the NHS notes that panic symptoms can also be symptoms of other conditions. Call 999 for chest pain that feels tight or squeezing or spreads to your arm, neck or jaw, for severe breathlessness, or for palpitations with chest pain, breathlessness or fainting. If you've had symptoms like these, get checked by a GP before harder exercise, even if they turned out to be panic before.
Do breathing exercises work for anxiety? Which is best?
They help a little: across 20 trials, breathing exercises reduced anxiety by a small amount. The best-supported pattern is simple slow breathing with no holds, which is what the NHS teaches: in gently for a count of 5, then out for a count of 5, for at least 5 minutes. Box and 4-7-8 breathing are popular, but the holds aren't needed, and some people with panic find them uncomfortable. For panic disorder, CBT matters more than breathing technique.
Is cardio or strength training better for anxiety?
Both help, and the evidence doesn't clearly favour one. Network analyses rank strength training among the most effective types, and aerobic exercise also helps. A mix, such as the largest trial's cardio and strength circuits, is a good choice.
Is yoga good for anxiety?
It helps anxiety symptoms in pooled trials. In the largest trial in GAD, yoga did better than stress education but not as well as CBT, and only CBT's benefit lasted to 6 months. Yoga is a good addition, not a replacement for therapy.
Can exercise replace therapy or medication for anxiety?
No. In panic disorder, group CBT worked better than group exercise, and an antidepressant worked better than running. Exercise is a useful add-on. Don't stop a medicine without talking to your doctor. In England, you can refer yourself to NHS talking therapies.
I take propranolol. Can I exercise?
Usually, yes. Beta blockers such as propranolol slow your heartbeat, so heart rate targets won't fit: use the talk test instead. Propranolol can make you feel tired or dizzy; if you feel dizzy, sit or lie down. Ask your GP if you have a heart condition or new symptoms.
