Atherosclerosis: Stress, Lack Of Sleep & Exercise And Poor Diet Raise Risks

Swirski acknowledged that “there is no question” that genetics play a role in cardiovascular health, but in the last several years, four risk factors — stress, sleep interruption or fragmentation, diet, and sedentary lifestyle — have been clearly identified as contributing to atherosclerosis, commonly referred to as hardening of the arteries, which can lead to a variety of complications, including death.

Science: ‘The Biggest Breakthroughs In Biology In 2020’ (Video)

In 2020, the study of the SARS-CoV-2 virus was undoubtedly the most urgent priority. But there were also some major breakthroughs in other areas. We’d like to take a moment to recognize them.

  • 1. This year, we learned that we had severely underestimated the human brain’s computing power. Researchers are coming to understand that even the dendritic arms of neurons seem capable of processing information, which means that every neuron might be more like a small computer by itself.
  • 2. The new Information Theory of Individuality completely reimagines the way biologists have traditionally thought about individuality. Armed with information theory, the researchers found objective criteria for defining degrees of individuality in organisms.
  • 3. Deprived of sleep, we and other animals die within weeks. More than a century of scrutiny failed to explain why lack of sleep is so deadly. This year, an answer was finally found — not inside the brain, as expected, but inside the gut.

Studies: “Insomnia / Short Sleep Duration” Is A Type 2 Diabetes “Risk Factor”

Diabetologia  (Sept 8, 2020) – Insomnia with objective short sleep duration has been associated with an increased risk of type 2 diabetes in observational studies [2728]. The present MR study found strong and suggestive evidence of a causal association of insomnia and short sleep duration, respectively, with increased risk of type 2 diabetes.

Conclusions/interpretation

The present study verified several previously reported risk factors and identified novel potential risk factors for type 2 diabetes. Prevention strategies for type 2 diabetes should be considered from multiple perspectives on obesity, mental health, sleep quality, education level, birthweight and smoking.
