Having a chronic illness can sometimes lead to the development of anxiety - something that can lower people's quality of life and make them less likely to follow their treatment plans. Researchers from the University of Georgia have been looking into the effectiveness of exercise in reducing this anxiety in a review of 40 studies covering nearly 3,000 patients with a variety of medical conditions. The researchers found that, on average, the patients who exercised regularly reported a 20% reduction in anxiety symptoms. Exercise sessions greater than 30 minutes were better at reducing anxiety than those of less than 30 minutes but programmes of exercise of between 3-12 weeks were actually more effective than those of more than 12 weeks- perhaps because they were less daunting for the participants.
