“A small randomized trial also found that regular didgeridoo practice improved daytime sleepiness and reduced the apnea-hypopnea index, illustrating how upper-airway muscle training may help some patients alongside established sleep-medicine care.”

“Family-controlled research provides another view. A Swedish cohort of 2.48 million children found small associations in conventional models, but the estimates moved to the null when siblings with different prenatal exposure were compared.”

“Research in trained cyclists found that daily heart rate variability tracked training load and perceived exertion during an overload period, then returned toward baseline during recovery, supporting its use as a sensitive signal when interpreted against an individual's normal range.”

“While it’s likely that there may be more going on with depression than just inflammation by itself, it could be an incredibly useful lens through which to look at promising avenues to potentially treat or prevent it, since controlling systemic inflammation shows promise as being both important for longevity and health in general.”

“New Scientist article. 02:06:10 - Some people, like Tom Cruise and Keanu Reeves, seem to defy aging. 02:08:15 - One 12-ounce can of sugar-sweetened soft drink per day shortened telomere length, corresponding to 4.6 years of biological aging.”

“Rumination, the practice of dwelling on external stressors to excess, can set in motion a cascade of hormonal and physiological responses that harm mental and physical health. Meditation has been shown to reduce rumination and its negative effects, however, and influences the gene expression of as many as 500 genes, many of which are in the brain.”

“Using a Mendelian randomization analysis, scientists determined that people carrying genetic variants associated with low vitamin D levels have higher mortality from respiratory tract infections and higher all-cause mortality.”

“A few examples of genes with common polymorphism discussed are MTHFR and folate, NBPF3 and vitamin B6, FUT2 and vitamin B12, BCMO1 and beta-carotene, FADS2 and omega-3 fatty acids, CYP2R1 and vitamin D, PEMT and choline as well as APOE4 and FOXO3.”
