Although acute bright light and melatonin administration affected subjective sleepiness, internal sleep structure and EEG power density during sleep and wakefulness in a additive manner, the phase shifting effect of a single evening bright light exposure could not be blocked by exogenous melatonin.
Is Sleep per se a Zeitgeber in Humans?
Sleep per se may feed back onto the circadian pacemaker, but it appears to be a weak zeitgeber in humans.
The hypothermic effect of late evening melatonin does not block the phase delay induced by concurrent bright light in human subjects
Seasonal depression and sleep disturbances in Alaska and Siberia: a pilot study.
The Physiological Period Length of the Human Circadian Clock In Vivo Is Directly Proportional to Period in Human Fibroblasts
The period of human circadian behaviour is mostly driven by cellular clock properties in normal individuals and can be approximated by measurement in peripheral cells such as fibroblasts, which suggests that period can be modified by prolonged unusual conditions such as the total light deprivation of blindness.
Melatonin Treatment of Winter Depression Following Total Sleep Deprivation: Waking EEG and Mood Correlates
Overall, patients with winter depression manifest similar wake EEG characteristics as long sleepers or late chronotype with respect to an insufficient build-up of homeostaticSleep pressure was an effective antidepressant treatment for some patients, but evening melatonin was not more efficacious than placebo in sustaining this antidepressant effect.
Effects of the Seasons and of Bright Light Administered at Different Times of Day on Sleep EEG and Mood in Patients with Seasonal Affective Disorder
The reduced amounts of slow wave sleep in the depressive state predicted higher reduction and low posttreatment scores on psychiatric scales and the total amounts and percentage ofslow wave sleep were significantly lower in responders to light compared to both nonresponders and controls.

The significantly steeper positive clinical dynamics observed in rTMS group in comparison with the placebo group was accompanied by a significant drop in spontaneous production of proinflammatory cytokines IFNγ and IL-17A.

It is suggested that the 25% clinical improvement is not related to nutrient diet or its timing, but rather to natural changes during the menstrual cycle, available sunshine, and ease of dieting for fatter patients.
White matter disturbances in major depressive disorder: a coordinated analysis across 20 international cohorts in the ENIGMA MDD working group
Alterations in white matter (WM) microstructure have been implicated in the pathophysiology of major depressive disorder (MDD). However, previous findings have been inconsistent, partially due to low…
