Self-reported morningness-eveningness related to positive affect-change associated with a single session of hatha yoga.

Pre-to-post positive affect change was greater in the yoga group (n = 45) compared to the control group (n = 25), with a significance level of p < 0.001.

• A single hatha yoga session is associated with an improvement in self-reported positive affect compared to a lecture control.
• There is a significant interaction between self-reported morningness-eveningness type and positive affect change in the yoga group.
• Evening types reported greater positive affect change from pre to post yoga compared to morning types, with a significance level of p = 0.01.
• Findings suggest a potential relationship between morningness-eveningness and emotional responses to yoga, warranting further long-term studies.
