Understanding Evidence Based Complementary Therapies for Mental Health

Complementary therapies can support mental health when used alongside standard care. This overview explains what they are, what evidence supports them, and how to use them safely with your healthcare team.

Understanding these options can help you tailor a plan to your needs and values, protect safety, and enhance outcomes alongside established treatments.

What complementary therapies include

Complementary therapies encompass a broad range of approaches that people use in addition to conventional care. They tend to fall into mind–body practices, physical activity, nutrition, and body-based or creative modalities. Examples include:

• Mind–body approaches: mindfulness, meditation, breathing exercises, progressive muscle relaxation, and guided imagery.
• Yoga, tai chi, and other movement therapies: practices that combine posture, breath, and awareness.
• Exercise and outdoor activity: regular aerobic activity and strength training tailored to ability and preferences.
• Sleep and light therapies: sleep hygiene strategies and, for seasonal mood symptoms, bright light exposure.
• Nutrition and supplements (with caution): balanced eating patterns, omega-3 fatty acids, vitamin D, and other supplements — always discussed with a clinician due to interactions with medications.
• Body-based therapies: massage, acupuncture, and other hands-on approaches performed by trained practitioners.
• Creative and expressive therapies: music, art, or drama-based activities used to support mood and coping.
• Herbal remedies and phytotherapy (careful use): herbs such as St. John’s wort, which can interact with many medications; obtain guidance before use.

Evidence for their effectiveness

The strength of evidence varies by therapy and condition. Some approaches have robust or growing support, while others are promising but require more high-quality trials. Always view complementary therapies as potential additions to, not replacements for, evidence-based treatment.

• Exercise: Substantial evidence shows regular physical activity can reduce depressive symptoms and anxiety and improve overall well-being. Start with a safe, sustainable plan and build gradually. Learn more.
• Mindfulness and meditation: Mindfulness-based approaches can help with stress, anxiety, and depressive symptoms for many people. See overview.
• Omega-3 fatty acids: Some evidence suggests benefits for mood symptoms, particularly in certain groups; results are mixed and dose matters. Details.
• Bright light therapy: Helpful for seasonal mood changes and certain circadian rhythm disruptions; often used under clinician guidance. Overview.
• Aromatherapy, massage, and acupuncture: May help with relaxation and symptom relief for some people; evidence varies by condition and quality of studies. Acupuncture and Herbal remedies require caution.

How complementary therapies work alongside traditional treatment

Complementary therapies are typically used in concert with conventional treatments such as psychotherapy and medications. They can help reduce symptoms, improve sleep and energy, support coping skills, and foster a sense of control and agency. Important considerations:

• Do not replace urgent or evidence-based care. If you have severe symptoms, thoughts of self-harm, or a marked change in functioning, seek immediate clinical help.
• Coordinate with your care team. Share any supplements, herbal products, or new modalities you’re trying to ensure they don’t interact with medications or treatments.
• Start safely and gradually. Begin with low intensity, monitor effects, and adjust with professional guidance.
• Monitor safety and quality. Seek qualified practitioners, especially for hands-on therapies or injections, and report adverse effects promptly.
• Respect individual differences. What helps one person may not help another. Personal preferences, culture, and accessibility shape what’s workable.

• Omega-3 fatty acids can be considered as an adjunct under medical supervision, with attention to interactions and dosing. What to know.
• Sleep regulation and consistent routines help reduce mood instability.
• Avoid certain herbal supplements (e.g., St. John’s wort) without clinician approval, as they can interact with mood stabilizers and other meds. St. John’s wort safety.

PTSD and trauma-related symptoms

For PTSD, several approaches may complement therapy and core treatment:

• Mindfulness-based and body-oriented practices can help with hyperarousal and intrusive thoughts. Mindfulness in context.

Sleep disorders and circadian rhythm issues

Good sleep is central to mental health. Complementary approaches that may help include:

• Sleep hygiene and relaxation practices to promote regular sleep timing and reduce wakefulness at night.

When to consider complementary approaches

• If you are already receiving treatment, discuss any new therapy with your clinician before starting.
• Prefer therapies with some evidence and clearly stated safety considerations; avoid unproven or overly aggressive claims.
• Be mindful of interactions with medications (for example, certain herbs or high-dose supplements can affect liver enzymes or mood stabilizers).
• Consider your goals, values, accessibility, and cost, and set realistic expectations about symptom changes.

Finding qualified practitioners

Choosing the right professional is important for safety and effectiveness. Consider the following steps:

• Verify licensing and credentials in your region. Ask about formal training, supervision, and ongoing education.
• Ask about experience working with mental health conditions and collaboration with your psychiatrist or psychologist.
• Request a concise plan, including realistic goals, safety considerations, and how progress will be monitored.
• Clarify what to do if you have adverse effects or if your symptoms worsen.
• Discuss costs, insurance coverage, and whether the approach is appropriate for your current treatment plan.
