Dr. Rhonda Patrick explains peakspan and how exercise, sleep, learning, and resistance training may preserve function with age.

“They found that older mice had nearly 40 percent fewer hypocretin-producing neurons than younger mice. The remaining neurons, which were more excitable than those present in younger mice, triggered wakefulness and poor sleep.”

“Dimming lights and curtailing our use of these devices in the evening allows melatonin to rise naturally, so we can sleep. A surprising connection between melatonin and blood sugar control Several converging branches of evidence suggest that melatonin inhibits insulin secretion, influencing blood glucose levels.”

“The end result is an upside-down sleep schedule in which circadian rhythms and gene expression in the body become desynchronized. In this clip, Dr. Satchin Panda describes the effects of inappropriate light signals and discusses strategies to mitigate their effects.”

“Potassium may contribute by allowing nerve and muscle cells to maintain stable electrical activity, which supports normal relaxation and sleep regulation. Together, these minerals could plausibly shift physiology away from heightened arousal and toward a more sleep-ready state.”

“The participants were exposed to either LED, OLED, or dim light for four hours prior to going to sleep. The study investigators assessed the participants' sleep quality via polysomnography as well as the participants' self-assessment.”

“This 2018 review describes the biological pathways that enhance slow-wave sleep, the deepest stage of non-REM sleep in humans, and how slow-wave sleep influences cognition.”

“Having a healthy, robust immune system is crucial for our survival. Critical players in the body's antiviral immune response are interferons. Certain lifestyle behaviors can boost interferon production and immune function, including sleep, vitamin D, and hot hydrotherapy.”

“Lastly, cannabis acts directly on the endocannabinoid system, which plays a role in both sleep and circadian regulation. Conclusion: The results suggest that starting cannabis use before age 18 is linked to a higher likelihood of insomnia in young adulthood.”

“Dr. Patrick also finds resveratrol in wine implausible as an explanation for benefit because dietary doses are far below experimental doses. Her broader interpretation is opinion constrained by the stronger structural, sleep, and cardiometabolic evidence.”
