Shift Work and Metabolic Syndrome Updates: A Systematic Review
Sleep Science, 2023 Shift work can cause circadian cycles disturbances and misaligns the endogenous rhythms. The physiological variables are driven by the circadian system and, its misalignment, can impair the metabolic functions.

Using plant circadian programs to optimize agrochemical use
New Phytologist, EarlyView.Summary Agrochemicals play an important role in maximizing agricultural yields. One class of agrochemicals is herbicides, which are used for weed control and to kill the top growth of certain crops before harvest. We examine the influence of plant circadian regulation on herbicide effectiveness to exemplify how knowledge of the circadian clock could be

BMC Nursing, 2021 Background Young adults are likely to have activities and go to bed late at night due to their age-dependent delayed endogenous circadian clock. The purpose of the present study was to clarify sleep–wake rhythm and its association with lifestyle, health ...

Acute intermittent hypercapnic hypoxia augments left ventricular contractility
The Journal of Physiology, EarlyView.Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Daily rhythm in DNA methylation and the effect of total sleep deprivation
Journal of Sleep Research, Volume 34, Issue 4, August 2025.Summary Numerous hormones and genes exhibit diurnal 24‐hr rhythms that can also be affected by sleep deprivation. Here we studied diurnal rhythms in DNA methylation under a 24‐hr sleep/wake cycle and a subsequent 29 hr of continual wakefulness (1 night of sleep deprivation).

Chronobiological Aspects of Mood Disorders
, 2012 Mood disorders, especially those related to depression, are among the most prevalent mental impairments. Therefore, understanding their etiology is important for prevention and improving therapy. Sub-clinical depressive symptoms, which predict the onset of mood and anxiety disorders (Gentil et al., 2007), are correlated with slow information processing,

The CIRCORT database: Reference ranges and seasonal changes in diurnal salivary cortisol derived from a meta-dataset comprised of 15 field studies [PDF]
, 2016 Diurnal salivary cortisol profiles are valuable indicators of adrenocortical functioning in epidemiological research and clinical practice. However, normative reference values derived from a large number of participants and across a wide age range are ...

Multi‐Wearable Approach for Monitoring Diurnal Light Exposure and Body Rhythms in Nightshift Workers
Acta Physiologica, Volume 241, Issue 7, July 2025.ABSTRACT Aim As our understanding of light's impact on human health grows, studies examining light exposure and related health outcomes in everyday settings are increasingly important, particularly in high‐risk groups like nightshift workers. Methods In this observational study, we monitored personal light exposure and physiological functions in a ...

Genetic basis of human circadian rhythm disorders. [PDF]
, 2013 Circadian rhythm disorders constitute a group of phenotypes that usually present as altered sleep-wake schedules. Until a human genetics approach was applied to investigate these traits, the genetic components regulating human circadian rhythm and sleep ...
