“As we'll learn from Dr. Campisi, senescent cells exhibit more than one so-called phenotype, and they arrive at these different cellular phenotypes as a consequence of different types of cellular stress or dysfunction.”

“Oxidative stress plays a critical role in aging, traumatic brain injury, and autism. Recent clinical evidence suggests that sulforaphane raises levels of the potent antioxidant glutathione in the plasma and brain.”

“Sauna use is associated with reduced risk of many diseases, including cardiovascular and neurodegenerative diseases. One mechanism that drives this reduced risk is likely heat shock proteins, a class of proteins produced by cells in response to stressful conditions such as heat exposure.”

“Scientists exposed patients to high heat using an infra-red device or hot yoga and found both modalities to have anti-depressant effects. Heat stress causes the release of beta-endorphins as well as dynorphin, an endogenous opioid.”

“Several mechanisms explain why, minute for minute, vigorous exercise outperforms moderate- and light-intensity activity for achieving several heath benefits. Shear Stress and Endothelial Function Vigorous exercise dramatically increases blood flow and shear stress—the friction of blood sliding along the inner surface of blood vessels.”

“Experimental work also shows that a stress-is-enhancing mindset can change cognitive, emotional, and hormonal responses during a laboratory stressor. Dr. Huberman presents repeated practice as a way to help motivation and reward systems recognize productive effort.”

“These differences are often reflected in certain biomarkers and disease states that can predict biological age. Eating right, exercising more, and managing our stress can help us achieve our resolutions.”

“Currently selected for this coming member's digest by team member Sofia D.”

“Stress, pathology, and aging can alter brain energy metabolism. During times of impaired brain energy, the brain may prefer to use ketones as a fuel source. The use of alternate fuel sources allows glucose to be spared for the metabolic pathways that require it.”

“Whether extreme endurance exercise suppresses immune function transiently due to stress hormones such as cortisol or via another mechanism is a subject of much debate. In this clip, Dr. Rhonda Patrick describes how varying levels of exercise affect the immune response in different ways.”
