Why the study?
Frequent mild stress in modern society highlights the need to better understand psychophysiological responses to stressors, which may relate to dynamically organized neural structures reflected in heart rate variability.
Does adding mild stress during a cognitive task alter entropy of heart rate dynamics in healthy participants?

Entropy may mark acute stress in anxiety responders; leaves open validation as a specific biomarker.
Does adding mild stress during a cognitive task alter entropy of heart rate dynamics in healthy participants?
Entropy of heart rate dynamics may serve as a specific physiological marker for acute mild stress, particularly in individuals who exhibit anxiety responses.
