Multi‐Wearable Approach for Monitoring Diurnal Light Exposure and Body Rhythms in Nightshift Workers

open access: yesActa 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 ...

Standardized and Calibrated Light Stimuli via Head‐Mounted Displays for Investigating the Nonvisual Effects of Light

open access: yesJournal of Pineal Research, Volume 77, Issue 4, July 2025.
ABSTRACT Light influences human physiology profoundly, affecting the circadian clock and suppressing the endogenous hormone melatonin. Experimental studies often employ either homogenous full‐field stimulation, or overhead illumination, which are hard to standardize across studies and laboratories.

Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

open access: yesMammal Review, Volume 55, Issue 3, July 2025.
ABSTRACT Animals experience seasonal fluctuations of photoperiod, food availability, temperature and precipitation. This affects their energy budget, often leading to seasonal reproduction. We review available literature and (re)‐analyse existing datasets on seasonal reproduction of South American caviomorph rodents that are characterised by long ...

Regulation of pupil size in natural vision across the human lifespan

open access: yesRoyal Society Open Science
Vision is mediated by light passing through the pupil, which changes in diameter from approximately 2 to 8 mm between bright and dark illumination. With age, mean pupil size declines.

A review of psychosocial factors and personality in the treatment of obstructive sleep apnoea

open access: yesEuropean Respiratory Review, 2019
Effective treatment of obstructive sleep apnoea (OSA) is primarily determined by adherence to the selected intervention. The most common treatment pathways are mechanical devices such as continuous positive airway pressure (CPAP) or a mandibular ...

Chronobiology in endocrinology.

open access: yesAnnali dell'Istituto superiore di sanita, 1993
Temporal endocrine structure (TES). It can be defined as a combination of predictable hormonal changes that are time-related. Regarding their frequency, endocrine rhythms may be circadian, ultradian and infradian. In this context, the endocrine circadian time structure (ECTS), that is closely dependent of some areas of the hypothalamus, is of ...
