Discussion

This study uncovers mental stress impacts on heart responses in males and females, suggesting sex-specific implications.

Response-locked heart rate data highlighted significant differences in heart responses between men and women during stress.
Men exhibited earlier and longer-lasting heart rate decelerations, indicating a time-based regulation strategy under stress.
Women showed larger, short-lived heart rate swings that reflected intensity-based responses to stress tasks.
Neural responses revealed sex-specific stress effects, with different brain wave patterns impacting cognitive control for each sex.

Wriessnegger et al. (2025) studied this question.
