DOI: 10.1016/j.clinph.2018.04.721
Abstract: Introduction In the past, the suppression of the pineal hormone melatonin by light has been investigated in several studies, frequently using small samples and only male subjects. Whereas the nocturnal melatonin production is thought to… read more here.

DOI: 10.1080/07420528.2020.1752704
Abstract: ABSTRACT Exposure to light at night results in disruption of endogenous circadian rhythmicity and/or suppression of pineal melatonin, which can consequently lead to acute or chronic adverse health problems. In the present study, we investigated… read more here.

DOI: 10.1080/07420528.2023.2188091
Abstract: ABSTRACT Light is the main environmental signal synchronizing circadian rhythms to the 24-hour light-dark cycle. Recent research has identified significant inter-individual variability in the sensitivity of the circadian system to light as measured by, among… read more here.

DOI: 10.1111/jpi.12780
Abstract: Light at night in adults suppresses melatonin in a nonlinear intensity‐dependent manner. In children, bright light of a single intensity before bedtime has a robust melatonin suppressing effect. To our knowledge, whether evening light of… read more here.

DOI: 10.1111/jpi.12786
Abstract: Light‐induced melatonin suppression data from 29 peer‐reviewed publications was analysed by means of a machine‐learning approach to establish which light exposure characteristics (ie photopic illuminance, five α‐opic equivalent daylight illuminances [EDIs], duration and timing of… read more here.

DOI: 10.1177/0748730418784041
Abstract: Studies with monochromatic light stimuli have shown that the action spectrum for melatonin suppression exhibits its highest sensitivity at short wavelengths, around 460 to 480 nm. Other studies have demonstrated that filtering out the short… read more here.
