<jats:title>Abstract</jats:title><jats:p>Chronically heightened physiological reactivity to or delayed recovery from stress may contribute to cardiovascular (<jats:styled-content style="fixed-case">CV</jats:styled-content>) risk and mortality. Long‐term stability of physiological stress responses has received little attention. Our objectives were to evaluate the 3‐year stability of reactivity and recovery change scores across <jats:styled-content style="fixed-case">CV</jats:styled-content> and autonomic parameters and assess whether sex and age moderate stability. A total of 134 healthy participants underwent two laboratory stress protocols, including four 5‐min interpersonal stressors, each followed by a 5‐min recovery period. Heart rate (<jats:styled-content style="fixed-case">HR</jats:styled-content>), blood pressure (<jats:styled-content style="fixed-case">BP</jats:styled-content>), and <jats:styled-content style="fixed-case">HR</jats:styled-content> variability (high frequency, low frequency, very low frequency [<jats:styled-content style="fixed-case">VLF</jats:styled-content>]) were obtained. Spearman rank correlations and linear regressions were performed. Significant correlations emerged for all physiological measures except diastolic <jats:styled-content style="fixed-case">BP</jats:styled-content> and <jats:styled-content style="fixed-case">VLF</jats:styled-content> recovery. No significant sex or age differences were found. Stress responses represent stable individual traits little affected by sex or age.</jats:p>
