From a Sleep Medicine online release (January 2020):
Our findings suggest that LAN (low-level light at night) exposure increases the incidence of diabetes in a general elderly population. Further research involving a large cohort with new-onset diabetes is warranted to elucidate these findings.
Highlights
- Humans are commonly exposed to light at night.
- Higher light exposure at night was significantly associated with higher incidence rate of diabetes.
- The association was consistent in the analysis using the cut-off values of LAN as 3 and 5 lux.
- Strengths include large samples adjusting a number of confounders.
The circadian timing system, located within the suprachiasmatic nucleus of the hypothalamus, controls fundamental energy homeostasis. Clock gene mutations induce obesity in mice, and the disruption of internal circadian rhythms decreases daily energy expenditures and leptin levels in humans. Light information received by the brain influences human circadian timing and metabolism; low-level light at night (LAN) significantly increased body mass and led to prediabetes in mice. In humans, bedroom LAN affected obesity parameters; however, the association between LAN and the incidence of diabetes in humans has not been studied.
By comparing the pancreatic cells of type 2 diabetic human donors with those of healthy people, researchers at the University of Geneva (UNIGE) and at the University Hospitals of Geneva (HUG), Switzerland, were able to demonstrate, for the first time, that the pancreatic islet cells derived from the Type 2 Diabetic human donors bear compromised circadian oscillators. 
Though a law requiring clinical trial results reporting has been on the books for decades, many researchers have been slow to comply. Now, 2 years after the law was sharpened with higher penalties for noncompliance, investigative correspondent Charles Piller took a look at the results. He talks with host Sarah Crespi about the investigation and a surprising

In people with Type 1 diabetes, the pancreas can’t make insulin. Those with the condition require several doses of insulin a day and spent $5,705 per person on it in 2016, an increase of $2,841, or 99%, per person since 2012, according to the nonprofit 
Costs continue to rise, so much so that almost half of people with diabetes have temporarily skipped taking their insulin, according to a 2018 survey by UpWell Health, a Salt Lake City company that provides home delivery of medications and supplies for chronic conditions.
“What you want is more, small fat cells rather than fewer, large fat cells,” Jackson said. “A large fat cell is not a healthy fat cell. The center is farther away from an oxygen supply, it sends out bad signals and it can burst and release toxic contents.” Large fat cells are associated with insulin resistance, diabetes and inflammation, he added.
When people are awake during the night, their behaviors are often mismatched with their internal body clocks. This can lead to nighttime eating, which can influence the way the body processes sugar and could lead to a higher risk in diabetes. “What happens when food is eaten when you normally should be fasting?” Scheer asked the audience. “What happens is that your glucose tolerance goes out the window….So your glucose levels after a meal are much higher.” This can increase people’s risk for diabetes.
Physical inactivity, smoking, high blood pressure, diabetes, and high cholesterol play a greater role than genetics in many young patients with heart disease, according to research presented today at ESC Congress 2019 together with the World Congress of Cardiology. The findings show that healthy behaviours should be a top priority for reducing heart disease even in those with a family history of early onset.
