    Opis:
    Night-shift workers may develop poor cardiovascular health. Studies about heart rate variability (HRV) metrics could identify risk factors in this population and be used to examine the effectiveness of interventions for optimizing the health of night-shift workers. The purpose of this review was to examine the use of HRV methodologies in studies about night-shift work. Overall, 34 articles met the selection criteria and underwent a methodological critique. The main conclusion across these studies was that night-shift work could increase the sympathetic influences on the variability between heartbeats. In many cases, however, important methodological details were omitted (e.g., the number and duration of electrocardiogram recordings, sampling rates, R–R segment duration, wavelet transform methods). Recommendations include adding measures of disease outcomes, using ≥250 Hz sampling rates and 600-s R–R segments, and measuring sleep and circadian rhythms. With these approaches, researchers can design investigations that identify therapeutic targets for improving the health of night-shift workers.

    Opis:
    Sleep is a very important aspect of human life, as it is responsible for regulation of the circadian cycle, body regeneration and reduction of harmful metabolites. Sleep deprivation can be associated with chronic stress, which can have an extremely negative impact on bodily function. The presented study covered 220 students of medical faculties; their correlations between the sleep quality and the level of perceived stress were analyzed. Sleep quality was measured using the PSQI (Pittsburgh Sleep Quality Index), and perceived stress was measured using PSS-10 (10-Item Perceived Stress Scale). A high correlation was shown between the PSQI and PSS-10 results (rs = 0.60), which means that people who were characterized by a low sleep quality also showed a high level of perceived stress. Among the PSQI components that were the most correlated with PSS-10, can be counted in such components as C1 (subjective sleep quality, rs = 0.50), C2 (sleep latency,  rs = 0.51), and C7 (daytime dysfunctions, rs = 0.52). Mobile phone usage at bedtime has also been demonstrated to correlate with poor sleep quality. The study shows a significant relationship between sleep quality and the level of perceived stress, which has also been shown in other studies.
