Summary: This study investigates the contributions of different wavelengths of monochromatic light to human melatonin suppression and circadian resetting responses. The results show that, initially, short-wavelength (S) cones and long- and medium-wavelength (L+M) cones have a significant contribution, while the contribution of melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs) becomes dominant over time. The first few minutes of light exposure play a crucial role in the phase resetting response.

Summary: Combined melatonin and bright light therapies have significant effects on improving sleep and circadian outcomes, with better efficacy in elderly populations compared to patients with delayed sleep-wake phase disorder. Adverse effects of melatonin in elderly populations should be carefully considered, and future studies should further investigate the separate and combined effects of these therapies in different target populations.

Summary: This study aimed to analyze the influence of mothers' nighttime responses on the sleep-wake rhythm of their 1-month-old infants. Findings showed that immediately picking up 1-month-old infants may result in longer daytime sleep compared to nighttime sleep, possibly due to the stimulating effects of picking up the infant on sleep-wake rhythm formation.

Summary: This study investigates the differences in melatonin circadian timing and output, sleep characteristics, and cognitive function between myopic and non-myopic children. The findings reveal that myopic children have delayed melatonin secretion, lower levels of nocturnal melatonin output, delayed sleep timing, unstable sleep onset and wake-up time, and a preference for evening-type diurnal rhythm. Myopic children also exhibit slower reaction time in sustained attention tasks.

Summary: Light plays a key role in synchronizing circadian rhythms and sleep patterns. Exposure to dim artificial lighting in the evening can cause coordinated realignment of circadian rhythms, sleep patterns, and short-term memory processes in mice, even affecting molecular clock rhythms and neuronal activity patterns.

Summary: Availability of artificial light and light-emitting devices have changed human temporal life, but exposure to artificial light at night disrupts circadian rhythms and increases the risk of metabolic and cardiac disorders. Circadian rhythms, regulated by the suprachiasmatic nucleus (SCN), control physiological processes such as sleep and food intake. Modern lighting disrupts the molecular clock rhythms, leading to hormonal and metabolic disruptions. Understanding these disruptions and developing strategies to mitigate their effects is crucial for human health.

Summary: Artificial light at night (ALAN) disrupts natural circadian rhythms, impacting behavior and physiology in both humans and wildlife. Studies have shown that even low levels of ALAN can lead to changes in nighttime activity and cardiovascular health, emphasizing the need for research into the ecological impacts of light pollution.

Summary: The advent of electric lighting has greatly changed human perception of light and darkness, but it often fails to stimulate and synchronize the circadian system. This can lead to poor sleep and may contribute to the increased incidence of cardiovascular diseases. This contribution suggests incorporating daily exposures to light and darkness as lifestyle factors to reduce the risk and progression of cardiovascular diseases.

Summary: In this study, it was found that aging affects the peripheral circadian rhythmicity in the plasma lipidome. Aging individuals showed a decrease in amplitude and an earlier acrophase of lipid circadian rhythms compared to younger individuals. These findings suggest that aging alters the temporal relationship between central and lipid rhythms.

Summary: Research suggests that athletes often have poor sleep quality, but combining fixed sleep schedules with light regulation may lead to more consolidated sleep. Light regulation improved self-reported sleep onset latency and subjective sleep quality, especially with a strict sleep-wake schedule. However, less obtrusive methods should be explored to enhance protocol compliance.

Summary: Social distancing/lockdown policies during the COVID-19 pandemic may disrupt social rhythms and challenge circadian function, particularly in individuals with mood disorders. This qualitative study explored participants' subjective experiences of social disruption, identifying themes such as loss of daily activities, role of social interaction, altered time perception, and disruption to motivation and associated psychological effects. These findings suggest the concept of 'psychological drift' as a potential focus for future research.

Summary: The study found that bright lighting during the day and dim lighting at night can alter postprandial substrate handling, energy expenditure, and thermoregulation of overweight insulin-resistant individuals. Differences in light intensity have effects on various metabolic parameters and body temperature, indicating the importance of the indoor light environment for metabolic health in at-risk populations.

Summary: Analysis of light-induced melatonin suppression data reveals that melanopic EDIs, light exposure duration, pupil dilation, and S-cone-opic EDIs are the main factors affecting melatonin suppression. Melanopic EDIs are the best predictor for biological effects of light, especially at low illuminances.
