Tahkamo L, Partonen T, Pesonen AK
Published in Chronobiology International, Vol. 36 (2), pp. 151-170
Methodology
Meta-analysis of controlled experiments quantifying melatonin suppression from evening light of varying intensity and wavelength.
Key Findings
Short-wavelength evening light produced substantial dose-dependent suppression of endogenous melatonin secretion.
Conclusions
Light exposure is the dominant modifiable determinant of endogenous melatonin production.
Limitations
Laboratory conditions; individual sensitivity varies widely.
Supplements Studied
Short-wavelength evening light produced substantial dose-dependent suppression of endogenous melatonin secretion.
Outcomes Measured
Short-wavelength evening light produced substantial dose-dependent suppression of endogenous melatonin secretion
