“In a separate analysis of seven intervention trials involving people with type 2 diabetes, HbA1c fell by about 0.71 percentage points, total cholesterol by 23 mg/dL, and LDL cholesterol by 22 mg/dL.”

“Dr. Patrick begins with a prospective Finnish cohort in which men reporting four to seven sauna sessions per week had lower dementia and Alzheimer's disease incidence than men reporting one session. The study is observational, male-only, and cannot prove that sauna caused the lower risk.”

“Circadian rhythms modulate a wide array of physiological processes, including the body’s production of hormones that regulate sleep, hunger, metabolism, and others, ultimately influencing body weight, performance, and susceptibility to disease.”

“Other hormetic responses to cold exposure include increased production of PGC1-alpha, a protein that promotes mitochondrial biogenesis, the production of new, healthy mitochondria, and the activation of brown fat – a phenomenon once thought to occur only in newborns, but now known to occur in adults, especially after cold exposure.”

“Perhaps the most clear-cut examples of cryotherapy’s beneficial effects are observed in the brain, where levels of the hormone and neurotransmitter norepinephrine – responsible for vigilance, attention, focus, and positive mood – increase markedly when the body is exposed to extreme cold.”

“For example, while vitamin C acts primarily as an antioxidant at physiological concentrations of approximately 50 micromoles per liter, pharmacologic doses of intravenous vitamin C greater than 1 gram generate hydrogen peroxide, a type of reactive oxygen species produced by neutrophils to destroy pathogens such as viruses.”

“A perplexing aspect of SARS-CoV-2, the novel coronavirus that causes COVID-19, is that people respond to it in disparate ways — some exhibiting no symptoms at all, and others experiencing life-threatening complications.”

“A critical element in healthiness is the timing and content of our meals. Time-restricted eating, a form of daily fasting wherein the time of the day during which a person eats is limited, capitalizes on the body's natural circadian metabolic rhythms to promote health.”

“The impact of the ketogenic diet on gut bacteria has not been actively studied. In animal models high-fat diets are thought to provoke the release of endotoxin from bacterial cell membranes resulting in negative health consequences. In this clip, Dr. Dominic D'Agostino and Dr. Rhonda Patrick discuss the ketogenic diet and its implications for gut health.”

“For example, growing up in an overly hygienic environment increases a child's risk for developing autoimmune diseases, but exposure to dirt, especially from soil, pets, and roaches, in the first year of life may provide protection against asthma and allergy-related skin disease.”
