abstract

• Stress can cause cardiovascular alterations and maladaptive reactions. Stress management techniques such as controlled breathing could be helpful to decrease the physiological alterations caused by prolonged stress levels. With the use of transfer entropy (TE), we can assess the interactions between the cardiovascular and cerebral systems and assess whether these interactions are affected by the application of controlled breathing. In this study, a test protocol was conducted consisting of the stages of rest, first cognitive task (mental arithmetic Stroop), controlled breathing, second cognitive task (mental arithmetic Stroop), and recovery. The goal was to evaluate changes in TE between maneuvers in 17 healthy volunteers. The results showed that most interactions were from brain to heart in both cognitive tasks and that the sympathetic pathway was the most affected. In addition, a higher number of significant interactions from the heart to the brain in the second cognitive task after applying controlled breathing, specifically from the vagal part. This suggests that controlled breathing is indeed influencing task, but further training in the breathing technique is needed to find possible significant differences between the tasks. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.
