Summary: New research has found no evidence linking heart rate variability ( HRV ) to reactive aggression, overturning previous theories. HRV measures the variance in heartbeats, which has been linked to stress tenacity, but this study demonstrates that it is a less than trustworthy diagnostic of aggression.
This challenges the use of HRV in wearables like devices as a tool to manage anger. To better comprehend and avoid aggressive behavior, experts emphasize the necessity of searching for potent markers.
Important Information:
- HRV does no coincide with responsive anger, contradicting earlier conclusions.
- Smart HRV tracking devices are unable to accurately predict aggression or mental regulation.
- The hunt for potent biological indicators of anger is still continuous.

The theory that heart rate variability ( HRV ) is associated with aggressive behavior is discredited by new research from the University of St Andrews.
Led by Ph. D. member Annah McCurry from the School of Psychology and Neuroscience, the investigation,  , published , in , Aggressive Behavior, screened 705 earlier studies and found no proof that HRV correlates with reactive , anger.
HRV, or , heart rate variability, measures the variability in time between pulses, which is controlled by the brain’s autonomic nervous system. Smartwatches and other portable devices frequently track HRV, which may be used to assess one’s level of stress endurance in research. But, McCurry’s studies indicate that HRV may not be beneficial as an indication of anger.
According to McCurry, “aggression researchers want to identify aggression so we can stop it before it occurs.” We want to get an objective natural sign of feelings regulation because poor emotion regulation has been linked to aggression, and some have attempted to employ HRV as a marker.
” Our results are definitive: experts should stop using lower HRV as a marker of aggression”.
This implies that using portable technology to control or forecast emotional upset or aggression may be misleading.
Smart biology trackers like sports pieces are enjoyable, according to McCurry.
We are persuaded that the creation of a potent diagnostic may change how society can identify, anticipate, and control reactive anger in our society.
” The search for a remedy may continue because empirical information clearly indicates that HRV is not a productive diagnostic of hostility.”

” Principles of Arousal Predict a Link Between Heart Rate Variability and Reactionary Aggression: Meta-Analytic Benefits Disagree” by Annah McCurry et al. Aggressive Behavior
Abstract
Principles of Arousal Predict a Link Between Heart Rate Variability and Reactionary Aggression: Meta-Analytic Benefits Believe
According to Polyvagal theory, frequently hostile people may experience a diminished capacity to quiet down after arousal, which has led to the study of biological “biomarkers” of aggression to identify high-risk individuals.
Wearable technologies that can non-invasively measure heart rate variability ( HRV ), a cardiovascular phenomenon impacted by the parasympathetic ( “rest and digest” ) nervous system, are the most widely used research approach ( specifically reactive ) aggression.
However, there is a problem: no one has definitively assessed the effectiveness of HRV as a indicator of reactionary aggression. We surveyed an original 705 content, producing 48 impact estimates conducive to meta-analysis.
The results demonstrate that there is no connection between sensitive anger and HRV, contrary to polyvagal theory’s predictions.
We discuss the implications of this book finding for both theory and practice, taking into account both the difficulty of identifying successful biomarkers and the practical restrictions making scientific decisions in anger research.
We come to the conclusion that there is n’t any empirical proof that HRV can be used to identify aggression.
