“The locus coeruleus is the primary region of the brain responsible for norepinephrine production. It is located in the pons and participates in the body's response to stress, attention, emotion, motivation, decision-making, learning, and memory.”

“This was an observational study and did not identify mechanisms that drive the relationship between light exposure and behavior. However, the authors of the study posited that light exposure might influence norepinephrine release in the brain, promoting increased vigilance, alertness, and attention.”

“The mechanisms that drive these effects likely include increased expression of neurotrophic factors, increased availability of serotonin and norepinephrine, regulation of the hypothalamic-pituitary-adrenal axis, and reduced systemic inflammation.”

“Researchers asked four young, healthy adults to perform 20-second high-intensity sprints on an exercise bike under four different muscle temperature conditions: room temperature, after leg immersion in hot water (44°C/111.2°F), and after immersion in cool water (18°C/64.4°F and 12°C/53.6°F).”

“When produced during exercise (especially high intensity workouts like cycling, which shifts metabolism toward glycolysis to more quickly meet the high energetic demands), lactate switches on more than 600 genes involved in muscle adaptation, stimulates mitochondrial biogenesis – the process of making new mitochondria – and promotes protein synthesis, which is essential for muscle growth.”

“Some of the interesting things demonstrated in the study of Wim's technique: an increased release of epinephrine (greater than first time bungee jumpers while laying in bed!), norepinephrine, and increased anti-inflammatory cytokines (IL-10) while decreasing of the pro-inflammatory cytokines (TNF-alpha).”

“He discusses serotonin, dopamine, norepinephrine, rumination, anhedonia, and psychomotor slowing, but is equally clear that chemistry alone is often not enough. Biology works better when it is paired with self-management. Exercise is a useful example of self-management.”

“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.”

“- Practical details like temperature and duration of sauna use, the difference between a dry, wet and infrared sauna, sauna timing, as well as other forms of heat stress such as steam showers, hot baths, and hot yoga.”

“Dr. Rhonda Patrick discusses how conditioning the body to heat stress through sauna use, called "hyperthermic conditioning" may cause adaptations that increase athletic endurance (by increasing plasma volume and blood flow to heart and muscles) and potentially even muscle mass. She also discusses the profound effects of hyperthermic conditioning on the brain including cognitive function.”
