Healthline: There’s a two-way link between insomnia and depression, but there are many ways to treat both at the same time.
Cognitive-behavioral therapy (CBT). This short-term therapy is the first-line treatment for insomnia and is also often used to treat depression. CBT is led by a mental health professional who helps you learn how to identify and change thoughts and behaviors linked to insomnia or depression. It may be combined with other techniques to help you sleep better, including sleep hygiene and relaxation techniques.
Relaxation techniques. Practices such as deep breathing, visualization, progressive muscle relaxation, and biofeedback are often recommended to address insomnia. A 2020 meta-analysis found that relaxation techniques are safe and may reduce depression symptoms if practiced regularly.
Exercise. A 2021 meta-analysis found that regular exercise improved self-reported sleep quality, insomnia severity, and daytime sleepiness. And a 2016 review of 22 studies found that exercise was effective at treating depression, especially in combination with medication.
Mind-body practices. A 2019 systematic review suggests that practices such as yoga, tai chi, qigong, and meditation can improve symptoms of insomnia and, therefore, overall health. A 2017 review concluded that yoga may be helpful in reducing depression, although most studies on the topic were small and short in duration.
