21 Positive Affirmations for Mental Health

Affirmations have been studied in the context of mental health, and while they are not a standalone treatment for mental health conditions, they can be a helpful complementary tool. Here are a few studies and pieces of scientific evidence related to the use of affirmations for mental health:

Self-Affirmation and Health Behavior Change

A study published in the journal “Psychological Science” in 2013 examined the use of self-affirmation in health behavior change. The research found that self-affirmation interventions led to positive changes in health behaviors, such as increased physical activity and healthier eating habits. These changes were attributed to improved self-esteem and reduced defensive reactions to health messages.

Positive Affirmations and Stress Reduction:

A study published in “Social Cognitive and Affective Neuroscience” in 2016 explored the effects of self-affirmation on the brain’s response to stress. The research found that self-affirmation can reduce stress responses in the brain, particularly in regions associated with threat processing. This suggests that affirmations may help buffer against the harmful effects of stress.

Affirmations and Self-Esteem

Numerous studies have explored the relationship between positive self-affirmations and self-esteem. While not all of these studies are specific to mental health, they indicate that affirmations can contribute to improved self-esteem, which is closely tied to mental well-being.


It’s important to note that while affirmations can be a helpful tool for promoting a positive mindset, they are often most effective when used in conjunction with other mental health strategies, such as therapy, mindfulness, and self-care. Additionally, individual responses to affirmations may vary, and what works for one person may not work as effectively for another. As with any mental health approach, it’s advisable to consult with a mental health professional for personalized guidance and support.
