Ocular and systemic melatonin and the influence of light exposure.
Ostrin LA. Ostrin LA. Clin Exp Optom. 2019 Mar;102(2):99-108. doi: 10.1111/cxo.12824. Epub 2018 Aug 3. Clin Exp Optom. 2019. PMID: 30074278 Free article. Review.
Melatonin is a neurohormone known to modulate a wide range of circadian functions, including sleep. The synthesis and release of melatonin from the pineal gland is heavily influenced by light stimulation of the retina, particularly through the intrinsically photosen …

The effects of blue-light filtration on sleep and work outcomes.
Guarana CL, Barnes CM, Ong WJ. Guarana CL, et al. J Appl Psychol. 2021 May;106(5):784-796. doi: 10.1037/apl0000806. Epub 2020 Jul 13. J Appl Psychol. 2021. PMID: 32658494
Specifically, we theorize that wearing blue-light filtering glasses creates a form of physiologic darkness, thus improving both sleep quantity and quality. ...Considering that individuals vary in the timing of their circadian process, we propose that chronotype is a …

A circadian rhythm-gated subcortical pathway for nighttime-light-induced depressive-like behaviors in mice.
An K, Zhao H, Miao Y, Xu Q, Li YF, Ma YQ, Shi YM, Shen JW, Meng JJ, Yao YG, Zhang Z, Chen JT, Bao J, Zhang M, Xue T. An K, et al. Nat Neurosci. 2020 Jul;23(7):869-880. doi: 10.1038/s41593-020-0640-8. Epub 2020 Jun 1. Nat Neurosci. 2020. PMID: 32483349
The neural mechanisms underlying this day-night difference in the effects of light are unknown. Using a light-at-night (LAN) paradigm in mice, we showed that LAN induced depressive-like behaviors without disturbing the circadian rhythm. This effect was …

Light at Night and Disrupted Circadian Rhythms Alter Physiology and Behavior.
Bumgarner JR, Nelson RJ. Bumgarner JR, et al. Integr Comp Biol. 2021 Oct 4;61(3):1160-1169. doi: 10.1093/icb/icab017. Integr Comp Biol. 2021. PMID: 33787878 Free PMC article. Review.
The widespread adoption of electric lights during the past century has exposed animals, including humans, to significant light at night (LAN) for the first time in our evolutionary history. Importantly, endogenous circadian clocks depend on light

Circadian, Carbon, and Light Control of Expansion Growth and Leaf Movement.
Apelt F, Breuer D, Olas JJ, Annunziata MG, Flis A, Nikoloski Z, Kragler F, Stitt M. Apelt F, et al. Plant Physiol. 2017 Jul;174(3):1949-1968. doi: 10.1104/pp.17.00503. Epub 2017 May 30. Plant Physiol. 2017. PMID: 28559360 Free PMC article.
Wild types also were analyzed in various photoperiods and after transfer to free-running light or darkness. Rosette expansion and leaf movement exhibited a circadian oscillation, with superimposed transients after dawn and dusk. Diurnal responses were modified in cl …

Dark goggles and bright light improve circadian rhythm adaptation to night-shift work.
Eastman CI, Stewart KT, Mahoney MP, Liu L, Fogg LF. Eastman CI, et al. Sleep. 1994 Sep;17(6):535-43. doi: 10.1093/sleep/17.6.535. Sleep. 1994. PMID: 7809567 Clinical Trial.

We compared the contributions of bright light during the night shift and dark goggles during daylight for phase shifting the circadian rhythm of temperature to realign with a 12-hour shift of sleep. ...Dim light was < 500 lux. Both bright light

Seasonality in affective disorders.
Wirz-Justice A. Wirz-Justice A. Gen Comp Endocrinol. 2018 Mar 1;258:244-249. doi: 10.1016/j.ygcen.2017.07.010. Epub 2017 Jul 13. Gen Comp Endocrinol. 2018. PMID: 28711512 Review.
Seasonality has been documented in many functions, from mood to hormones to gene expression. Research on seasonal affective disorder initiated the first use of timed bright light as therapy, a treatment since extended to non-seasonal major depression and sleep-wake …
