The Effect of Diaphragmatic Breathing on Attention, Negative Affect and Stress in Healthy Adults

This study evaluated diaphragmatic breathing's effects on attention, stress, and negative emotions in 40 healthy adults over eight weeks. Participants trained in diaphragmatic breathing showed reduced salivary cortisol (stress hormone), improved sustained attention, and decreased negative emotions compared to a control group. These findings suggest diaphragmatic breathing as a simple, non-invasive way to boost focus and emotional well-being, making it a practical tool for managing stress and enhancing cognitive performance in daily life.

Practicing diaphragmatic breathing for 15 minutes daily can improve focus, reduce stress, and alleviate negative emotions. This study highlights its mental health benefits in healthy individuals. However, as the sample size was small and focused on a healthy population, the results may vary. Integrating this practice with other stress-reduction strategies, like exercise or mindfulness, can provide a balanced approach to cognitive and emotional health.
