Light Exposure, Sleep Quality, & Cardiometabolic Function | Journal Club | The Metabolic Link Ep.13

The Metabolic Link

You won’t be surprised to hear that a night of poor sleep can affect how good you feel the next day. But did you know that disruptions in sleep quality, especially when they occur chronically, can have a major negative impact on your cognitive function, mood, and overall metabolic health?

On this week’s Journal Club episode of The Metabolic Link, co-hosts Dr. Dominic D’Agostino, Dr. Angela Poff, and Victoria Field dive into two research publications exploring how meal timing in shift workers affects mood vulnerability and how light exposure during sleep impairs cardiometabolic function.

The first study sought to determine if night-time eating contributed to the increased risk of depression and anxiety observed in shift workers. Amazingly, daytime-only eating during a simulated night work environment was not associated with the same negative health outcomes that appeared in those who ate during the night-time hours, suggesting a potential intervention to combat some of the health risks of shift work. The second study revealed how exposure to light during sleep can negatively affect glucose homeostasis, insulin sensitivity, sleep quality, heart rate, and heart rate variability, even after only a single night. Join the Metabolic Link co-hosts as they dive into the fascinating details of these studies!
