In addition to affecting subjective emotional distress in adults reflected by their emotional state, household chaos might also influence more objectively assessed physiological stress. Physiological biomarkers such as salivary alpha-amylase (sAA) serve as a quick and noninvasive indicator of physical stress levels. Increased sAA corresponds with autonomous nervous system (ANS) activity, as the sympathetic and parasympathetic components of the ANS play a role in the physiological response to [...] that there were no significant time or condition effects on negative emotional state. Yet, sAA levels were higher in the chaos condition compared to the neutral condition.
