“Artificial lighting allows us to control our lighting levels around the clock. While lighting our world after sunset and before sunrise has undoubtedly benefited humanity, it can perturb circadian rhythms, harming physical and mental health.”

“These findings have powerful implications for humans in terms of the timing of cancer surgeries and treatments so as to capitalize on the body's circadian-regulated protective mechanisms. In this clip, Dr. Satchin Panda describes how circadian rhythms influence DNA damage and repair, especially in the setting of time-restricted eating.”

“The content of breast milk is profoundly influenced by circadian rhythms, the body's 24-hour cycles of biological, hormonal, and behavioral patterns. For example, analysis of human milk samples from more than 75 women taken every three hours during a single 24-hour period demonstrated that the amino acid content of the milk varied according to a circadian rhythm.”

“Eating late at night – particularly large meals – can be detrimental and, along with DNA damage, provides fertile ground for cancer to develop. In this clip, Dr. Ruth Patterson discusses how eating in accordance with the body's natural circadian rhythm may reduce the risk of breast cancer.”

“Previous research indicates that Ruminiclostridium 5 is associated with improved sleep. These findings suggest that eating a diet rich in prebiotics can help restore normal circadian rhythms following disruption, such as would occur after working shifts or traveling.”

“The probiotic also altered their gut microbial composition toward a more favorable profile and increased levels of isovaleric acid and gamma-aminobutyric acid (also known as GABA), metabolites involved in melatonin production and circadian rhythm regulation, respectively.”

“The study's authors posited that maintaining a consistent daily schedule and regular meals may help mitigate the effects of circadian rhythm disruption. Learn more about how shift work and jet lag influence circadian rhythms in this clip featuring Dr. Satchin Panda.”

“A 2019 study found that bright light may protect the heart by increasing the activity of a gene involved in circadian rhythms. Bright light also promotes blood flow to the heart. Researchers exposed 17 healthy adults to bright light (10,000 LUX, comparable to ambient daylight) for 30 minutes every morning for five days.”

“Circadian rhythms – the body’s daily cycles of biological, hormonal, and behavioral patterns – play critical roles in human health. Disturbances in these rhythms may increase susceptibility to metabolic disorders, such as diabetes and obesity.”

“It alters the expression of many genes involved in metabolism, circadian rhythm, immune response, and others. Interestingly, several studies indicate that metformin elicits similar gene expression profiles. Learn more about caloric restriction in this overview article.”
