Nighttime Light Hurts Mammalian Physiology: What Diurnal Rodent Models Are Telling Us

May 1, 2021
Mendoza, J. Nighttime Light Hurts Mammalian Physiology: What Diurnal Rodent Models Are Telling Us. Clocks & Sleep 2021, 3, 236-250. https://doi.org/10.3390/clockssleep3020014 Abstract Natural sunlight permits organisms to synchronize their physiology to the external world. However, in current times, natural sunlight has been replaced by artificial light in both day and nighttime. While in the daytime, indoor artificial light...

Circadian Misalignment and Metabolic Disorders: A Story of Twisted Clocks

April 5, 2021
Woller, A.; Gonze, D. Circadian Misalignment and Metabolic Disorders: A Story of Twisted Clocks. Biology 2021, 10, 207. https://doi.org/10.3390/biology10030207AMA Style Simple Summary In mammals, many physiological processes follow a 24 h rhythmic pattern. These rhythms are governed by a complex network of circadian clocks, which perceives external time cues (notably light and nutrients) and adjusts the timing of...

Evening home lighting adversely impacts the circadian system and sleep

November 10, 2020
Cain, S.W., McGlashan, E.M., Vidafar, P. et al. Evening home lighting adversely impacts the circadian system and sleep. Sci Rep 10, 19110 (2020). https://doi.org/10.1038/s41598-020-75622-4 Abstract The regular rise and fall of the sun resulted in the development of 24-h rhythms in virtually all organisms. In an evolutionary heartbeat, humans have taken control of their light environment with electric light. Humans...

Increase in eveningness and insufficient sleep among adults in population-based cross-sections from 2007 to 2017

September 22, 2020
Merikanto I, Partonen T. Increase in eveningness and insufficient sleep among adults in population-based cross-sections from 2007 to 2017. Sleep Med. 2020 Aug 19;75:368-379. doi: 10.1016/j.sleep.2020.07.046. Epub ahead of print. PMID: 32950882. Abstract Objectives: Short or long sleep duration, insufficient sleep, and Evening chronotype associate with many health issues and increased risk for mortality. Understanding population-level...

Light-entrained and brain-tuned circadian circuits regulate ILC3s and gut homeostasis

September 19, 2019
https://www.nature.com/articles/s41586-019-1579-3 Abstract Group 3 innate lymphoid cells (ILC3s) are major regulators of inflammation, infection, microbiota composition and metabolism1. ILC3s and neuronal cells have been shown to interact at discrete mucosal locations to steer mucosal defence2,3. Nevertheless, it is unclear whether neuroimmune circuits operate at an organismal level, integrating extrinsic environmental signals to orchestrate ILC3 responses....
