Breathing exercises and related practices such as mindfulness meditation have proven in recent years to be effective tools at combating stress. In a study published in Cell Reports Medicine, cyclic breathing was singled out as the most effective of three exercises— the other two being box breathing and cyclic hyperventilation. A co-author of this new study, Professor David Spiegel of Stanford University, had 114 study volunteers for the three forms of breathing, and the results are promising. Cyclic breathing may prove a great tool for managing stress and improving mental health after more intensive research. Read more about the study and cyclic breathing here.
