Small acts of kindness improve brain chemistry, 201 studies find
A review of 201 studies indicates that random, small acts of kindness can significantly improve mood and reduce stress.
Performing random small acts of kindness can improve brain chemistry by releasing mood-boosting hormones and reducing stress, according to a comprehensive review of 201 studies. The research suggests that small, spontaneous acts of kindness yield the greatest well-being benefits.
These actions trigger dopamine and serotonin release in the brain, enhancing mood, while also lowering the stress hormone cortisol. The positive effects extend to leadership, as kindness increases empathy and emotional intelligence. When others witness kind acts, it can create a positive ripple effect within an organization.
This phenomenon is known as "Helper's High," where the brain responds to acts of kindness in similar areas as receiving money. Neuroscience research suggests kindness is an evolutionary trait supporting the survival of social groups.
Opportunities for acts of kindness exist in daily life, such as offering a colleague assistance or buying coffee. Experts recommend performing even one small act of kindness daily to promote better mood and health.
