“…Nine studies [1, 6, 12-14, 16, 17, 19, 20] used ANOVA, ANCOVA or t-student test to investigate how HRV measures changed before and after the stress section. Of these, Traina et al, Papousek et al, and Lackener et al [12,13,15] converted frequencies domain HRV features with a log transform, while the remaining applied directly standard statistical significance tests to frequency domain measures, which are not normally distributed, being asymmetric distributions of positive numbers [21,22]. The selected studies reported ECG recordings at rest (resting session, RS) and during induced mental stress sessions (stress session, StS).…”

AbstractMental stress reduces performances, on the work place and in daily life, and is one of the first causes of cognitive dysfunctions, cardiovascular disorders and depression. This study systematically reviewed existing literature investigating, in healthy subjects, the associations between acute mental stress and short-term Heart Rate Variability (HRV) measures in time, frequency and non-linear domain. The goal of this study was to provide reliable information about the trends and the pivot values of HRV measures during mental stress. A systematic review and meta-analysis of the evidence was conducted, performing an exhaustive research of electronic repositories and linear researching references of papers responding to the inclusion criteria. After removing duplicates and not pertinent papers, journal papers describing well-designed studies that analyzed rigorously HRV were included if analyzed the same population of healthy subjects at rest and during mental stress. 12 papers were shortlisted, enrolling overall 758 volunteers and investigating 22 different HRV measures, 9 of which reported by at least 2 studies and therefore meta-analyzed in this review. Four measures in time and nonlinear domains, associated with a normal degree of HRV variations resulted significantly depressed during stress. The power of HRV fluctuations at high frequencies was significantly depressed during stress, while the ratio between low and high frequency resulted significantly increased, suggest...

“…These changes do not have a linear trend when related to temperature and humidity, and may have higher values at low or high temperatures. Several authors (Vimalanathan & Babu, 2014;Lan et al;BC et al, 2010;Liu et al, 2008;Vuksanović & Gal, 2007) found that the LF/HF ratio was higher at discomfort levels than at comfort levels, when describing the association between cardiac activity and the thermal sensation of an indoor space occupant (Lan et al, 2011). The increase in the LF / HF ratio indicates that the activity of the Sympathetic Nervous System (SNS) is high.…”

The increase in global temperature in recent years (which is likely to continue) has the power to affect the temperatures of indoor workplaces. This increase may in turn, be reflected in human performance. The present article analyzes the relationship between air temperature, blood pressure and heart rate variation in students in a learning environment through Video Display Terminals (VDT), located in northeastern Brazil. The thermal conditions were analyzed during three consecutive days, according to ISO 7726: 1998; in the group of students who underwent changes in indoor air temperature, their blood pressure and heart rate were also measured. When the air temperature was of 20ºC, 24% of the subjects' heart rate exceeded 100bpm, while for 30 °C this number reached 51%. The results revealed changes in diastolic blood pressure and heart rate when air temperature increases.

Multiscale entropy approach to physiological fatigue during long‐term Web browsing

Physiological fatigue during long-term Web browsing was investigated by the entropy-based method. A noninvasive instrument was used to gather 8-hour continuous electrocardiography signals from subjects who were asked to answer the psychological fatigue questionnaire every 2 hours. These data were used to calculate the heart rate (HR), traditional sample entropy (SampEn), and multiscale entropy (MSE). HR decreased as the browsing task began, but increased slightly after 4.5 hours. The psychological fatigue score gradually increased, implying that more severe subjective fatigue was experienced as Web browsing proceeded. In contrast, the traditional SampEn first increased and then oscillated after 2.5 hours. The browsing time of 2.5 hours may be a clue to physiological fatigue. The MSE results showed that the cardiac dynamic systems of undergraduates and males were more complex than those of graduates and females, respectively. Thus, SampEn may have the potential for estimating physiological fatigue during long-term Web browsing. C 2009 Wiley Periodicals, Inc.
