“Our daily sleep and activity rhythms and their associated metabolic states emerge from the interplay between circadian oscillators in our cells, exposure to light and darkness, and eating patterns. How does our body know what time of day it is?”

“Bright morning light helps anchor the circadian clock and can shift sleep timing earlier when a person's internal rhythm is delayed. Clinical evidence also suggests that light therapy can modestly reduce wakefulness after sleep onset in people with insomnia.”

“Melatonin release increases in the evening in response to low light and circadian rhythms to promote sleepiness. But it also binds to receptors in the gut that signal the pancreas to reduce insulin production.”

“Circadian rhythms, the body’s 24-hour cycles of biological, hormonal, and behavioral patterns, modulate a wide array of physiological processes, including the body’s production of hormones that regulate hunger, metabolism, sleep, and others.”

“Compounds in insecticides are structurally similar to melatonin and can bind to melatonin receptors. The activation of melatonin receptors tells the body that it is night and time for rest and this can potentially affect glucose homeostasis and insulin secretion.”

“The circadian rhythm is controlled by a central clock in the brain and by peripheral clocks in skeletal muscle, adipose tissue, and other organs. Together, these clocks coordinate the expression of genes related to a variety of metabolic processes with daily light, eating, and activity cycles.”

“The bright light exposure activated the prefrontal cortex. Exposure to bright light in the morning is what sets the biological clocks (circadian rhythm) that regulate 15% of the human genome including genes that produce neurotransmitters.”

“A consistent daily schedule may do more than support sleep—it could also help maintain physical fitness as we age. Robust evidence suggests that disruptions in circadian rhythms, such as those caused by shift work or jet lag, are linked to poorer health outcomes.”

“The timing of food intake strongly influences circadian rhythms. The authors of the study conducted a proteomic signature study – a type of analysis that identifies and quantifies the proteins present in a cell, tissue, or organism.”
