“This capacity of plant-based compounds to activate human cellular stress response pathways that confer protective effects is due to a biological phenomenon known as xenohormesis. In this clip, Dr. David Sinclair describes how plant-based compounds activate cellular protective mechanisms in humans.”

“A growing body of scientific evidence suggests that there's a correlation between nutrition, exercise, sleep, and stress management and having longer telomeres. Identifying the mechanisms that drive these correlations has proven challenging, but a few candidates stand out, including improvements in immune function and metabolic health.”

“In a randomized crossover study of 15 adults, a single weight-based dose changed cerebral energy metabolites and reduced deterioration on some cognitive tasks during about 21 hours without sleep. Dr. Patrick uses 10 grams daily and sometimes takes more during travel or sleep loss.”

“In a small trial involving adults with obesity, a ketone monoester improved one processing-speed task and selected brain blood-flow measures, providing an early signal for further research. Temperature can also shape alertness and sleep preparation.”

“The aggregate of these exposures is referred to as the "exposome" – the totality of non-genetic exposures that a person experiences during a lifetime – and includes nutritional, environmental, microbial, financial, and emotional factors.”

“Stress increases levels of hormones like adrenaline and cortisol, which in turn, can increase a person's blood pressure and heart rate. The different stages of sleep provide crucial periods during which the body recalibrates to promote both mental and physical well-being.”

“Hormesis is a compensatory defense response to a stressor that conditions the body against future stressors. Cold exposure, a powerful hormetic stressor, activates the body's cold shock response, the goals of which are simple: to reduce heat loss and increase heat production.”

“Other discussion... In addition to talking about some of the thermo- and pain- receptor stuff, Pierre and Rhonda also discuss other literature he's familiar with, including: Good stress and bad stress and how meditation affects the expression your genes.”

Senescence is a response to stress in which damaged cells terminate normal growth cycles to prevent.

“Ray talks about shifting one's perspective from looking at nutrition only through the lens of meeting day-to-day nutritional needs, and instead, also considering optimizing metabolism for longer-term effects as well, the importance of thinking about longevity in the context of functional healthspan, some of the similarities between the body’s physiological response to heat stress, cold stress…”
