Scientific research into the facial feedback hypothesis suggests that the physical act of smiling can influence emotional experiences and provide modest health benefits. Studies indicate that deliberately smiling can produce a small increase in happiness and may help lower cortisol levels, serving as a coping tool for stress or anxiety.

Experts, including Stanford University professor Jeanne Tsai, note that the physical sensation of a smile can independently affect emotional experience. While the effects may vary between social and solitary settings, the practice is being utilized in educational environments to reduce stress and increase motivation. Clinical experts suggest these benefits can assist individuals managing anxiety or depression, though they emphasize that smiling is not a replacement for professional mental health treatment.
