“Although smells are among the strongest cues in inducing and retrieving memories, sounds can also provide strong stimuli for learning. In this clip, Dr. Matthew Walker describes how sound and smell cues played during learning and subsequent sleep can enhance memory formation and retrieval.”

“But caffeine can also reduce sleep quality, fueling a vicious cycle of poor sleep, daytime grogginess, and increased caffeine consumption. This episode of the Aliquot features Drs. Guido Kroemer, Satchin Panda, Matthew Walker, Elissa Epel, and Rhonda Patrick (in an interview with Mike Maser).”

“Cognitive behavioral techniques can help people who have insomnia identify what those changes are and develop strategies that promote sleep, such as practicing good sleep hygiene, stimulus control, and sleep restriction.”

“Imagine a drug that improves sleep, reduces stress, sharpens focus, and boosts mood—without cost or side effects. That "drug" is light. Natural light is more than just illumination; it's a potent regulator of our body's internal clock, driving critical processes like hormone release and sleep-wake cycles.”

“In this clip, Dr. Matthew Walker describes how the different stages of sleep influence emotional and cardiovascular health. This Aliquot segment features professor of neuroscience and psychology Dr. Matthew Walker, an expert in sleep research.”

“Although alcohol may help us feel calm and ready to sleep, it has surprising effects on REM sleep and maybe our waking behaviors too. In this Aliquot, Dr. Matthew Walker, Tim Ferriss, and I discuss some of the risks and surprising effects of alcohol on human health and behavior.”

“Randomized sleep-restriction studies support a direct effect of inadequate sleep on insulin action, though the size of the effect depends on the population and protocol. Dr. Rhonda Patrick adds a personal postpartum CGM observation in which vigorous exercise improved her glucose pattern after disrupted sleep.”

“Five grams of creatine per day increased total sleep duration on resistance-training days compared with placebo, while the groups did not differ in overall sleep quality. The result introduces sleep as a promising new area of creatine research.”

Dr. Rhonda Patrick discusses fragmented sleep, lipid biomarkers including ApoB and LP(a), coffee makers and bean quality, and choline supplementation.

“The decline of deep, slow-wave sleep begins early in life, and by the time a person is in their 80s, their deep sleep brain waves are almost undetectable. The fact that poor sleep is linked with the aggregation of amyloid-beta plaques in the brain and Alzheimer's disease is not surprising.”
