Chronobiology of Exercise: Evaluating the Best Time to Exercise for Greater Cardiovascular and Metabolic Benefits.
Sign Up to like & getrecommendations! Published in 2022 at "Comprehensive Physiology"
DOI: 10.1002/cphy.c210036
Abstract: Physiological function fluctuates across 24 h due to ongoing daily patterns of behaviors and environmental changes, including the sleep/wake, rest/activity, light/dark, and daily temperature cycles. The internal circadian system prepares the body for these anticipated behavioral… read more here.

DOI: 10.1007/s00213-018-5019-0
Abstract: RationaleDisturbances of the circadian system are common in depression. Though they typically subside when depression is treated with antidepressants, the mechanism by which this occurs is unknown. Despite being the most commonly prescribed class of… read more here.

Eat, sleep, repeat: the role of the circadian system in balancing sleep–wake control with metabolic need

DOI: 10.1016/j.cophys.2020.02.003
Abstract: Feeding and sleep are behaviours fundamental to survival, and as such are subject to powerful homeostatic control. Of course, these are mutually exclusive behaviours, and therefore require coordinated temporal organisation to ensure that both energy… read more here.

DOI: 10.1016/j.psyneuen.2019.01.016
Abstract: The risk for adverse cardiovascular events (e.g., myocardial infarction, sudden cardiac death) peaks in the morning, possibly due to the effects of the endogenous circadian system on cardiovascular risk factors, or the occurrence in the… read more here.

DOI: 10.1016/j.smrv.2016.06.010
Abstract: Adolescents are vulnerable to inadequate sleep due to a unique constellation of risk factors. In particular, the puberty-related phase delay in the timing of the circadian system postpones the onset of sleep. Resultantly, disordered sleep… read more here.

DOI: 10.1080/07420528.2018.1461110
Abstract: ABSTRACT Stress is conditioning animal welfare by negatively affecting a wide range of physiological and behavioral functions. This may be applied to circadian physiology and food intake. Cortisol, the stress-related hormone, may mediate such effect… read more here.

DOI: 10.1080/07420528.2018.1465070
Abstract: ABSTRACT Exposure to light at night is a disruptive condition for the adult circadian system, leading to arrhythmicity in nocturnal rodents. Circadian disruption is a risk factor for developing physiological and behavioral alterations, including weight… read more here.

DOI: 10.1080/07420528.2018.1486851
Abstract: ABSTRACT Insects express diverse behavioral rhythms synchronized to environmental cycles. While circadian entrainment to light–dark cycles is ubiquitous in living organisms, synchronization to non-photic cycles may be critical for hematophagous bugs that depend on rhythmic… read more here.

DOI: 10.1093/sleep/zsad077.0008
Abstract: Major adverse cardiovascular events occur most commonly in the morning compared to other times of the day or night. Evaluation of coronary microvascular reserve perfusion can be used to reflect the anatomic and functional status… read more here.

DOI: 10.1098/rspb.2021.1943
Abstract: The melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs) are characterized by a delayed off-time following the cessation of light stimulation. Here, we exploited this unusual physiologic property to characterize the exquisite sensitivity of the human… read more here.
