“…Given the two‐hour window over which features were extracted for the second time point, the latter effect may be minor, although it can nevertheless be disregarded as the study did not include a control group of infants not receiving caffeine. These findings suggest an enhanced reactivity of the autonomic nervous system following a loading dose of caffeine in preterm infants, as characterised by increased vagally mediated heart rate and blood pressure variability.…”

“…Considerable uncertainty remains regarding the effect of caffeine, with conflicting evidence of cardiac, blood pressure and cerebral blood flow effects and increased vagal or sympathetic tone quantified by HRV analyses . Caffeine may increase vagally mediated HRV, although these findings are largely reported in adults with studies with heterogeneous study design and demographics .…”

“…The following demographic and health-related characteristics previously shown to influence cardiac vagal tone (28–33) were assessed: age, sex, alcohol and caffeine consumption (yes/no), smoking (yes/no), and regular physical exercise (yes/no). In addition, body mass index (BMI) was calculated based on participants’ self-reported weight and height.…”

Objectives Given the important role of the autonomic nervous system (ANS) in stress regulation, astonishingly little is known about ANS functioning in burnout, a condition arising after prolonged exposure to work-related stress. The current study sought to investigate ANS modulation, as indexed by vagally-mediated heart rate variability (HRV), in relation to burnout symptomatology to (i) distinguish associations between the three dimensions of burnout [emotional exhaustion (EE), cynicism, reduced personal accomplishment] and (ii) investigate overlap in associations with depressive symptomatology. Methods Assessments of vagally-mediated HRV (ie, root mean square of successive differences, RMSSD) were conducted in a large population-based sample from the Dresden Burnout Study [N=410, mean age 42.2, standard deviation (SD) 11.2 years; 33.4% male]. Vagally-mediated HRV was assessed for 90 seconds during an emotionally-arousing situation (venipuncture, recumbent), a 335-second recumbent recovery period, and a 335-second seated resting condition. Results Results from multiple linear regression analyses revealed that EE was negatively related to RMSSD during venipuncture (β= −0.11, P=0.03) and the seated rest (β= −0.09, P=0.04) even after accounting for established ANS modulators (eg, age, body mass index). This pattern was not observed for the other dimensions of burnout. Exploratory analyses of depressive symptomatology further revealed that RMSSD was significantly and inversely associated with burnout-related symptoms but not with the core criteria of depression (eg, depressed mood). Conclusions This study presents evidence for a link between exhaustion and reduced vagal function, both in burnout and depression, suggesting that ANS modulations may not be disorder-specific but rather a psychophysiological correlate of an underlying feature shared by both conditions.

“…DISCUSSION Effect of caffeine on autonomic nervous system is well known. Even though many articles have discussed the effect of coffee or caffeine consumption using HRV, results were contradictory [9]. Some studies support that coffee intake can increase the high frequency (HF) power indicating an increase in parasympathetic activity while others assert no significant effect on HRV.…”

It is well known that coffee has significant affect in the functioning of autonomic nervous system (ANS). Non-invasive study of ANS by heart rate variability was well documented. We aimed to study the effect of one cup of early morning coffee ingestion in healthy adults. We included total 35 healthy college going students with a mean age of 21.628 years. 5 minutes continuous photoplethysmogram(PPG) signal was recorded in three steps: one before coffee intake and after that two readings at an interval of 30 minutes after coffee intake. 12 features defining heart rate variability were obtained using Kubios software and significant difference were computed using statistical analysis. Only high frequency power indicating parasympathetic division of ANS showed significant decrease after half an hour of coffee intake which was again neutralised after one hour.
