“They also bolster previous research demonstrating that horizontal eye movements, such as those used when reading or viewing television, improve memory. Other lifestyle factors, including sleep, influence dementia risk, too. Learn more in this video featuring Dr. Rhonda Patrick.”

“As these plastic items degrade, they contribute to the growing problem of microplastics, which can carry harmful chemicals like flame retardants into the environment and the food chain, further amplifying health risks. Learn more about microplastics in this video featuring Dr. Rhonda Patrick.”

“The useful step is to turn that emotional contrast into a specific behavior rather than waiting to feel motivated. When a task still feels difficult to start, Dr. Huberman suggests doing something safe that feels even more uncomfortable, such as a cold plunge or a short bout of hard exercise.”

“In a randomized trial, a one-week social-media break improved well-being and reduced self-reported depression and anxiety compared with usual use, although the study did not establish one universal limit for every platform or person.”

“The comparison depends on what a dietary fat replaces. Randomized trials show that replacing palmitic acid, a common saturated fat, with unsaturated fats lowers LDL cholesterol and apolipoprotein B without a consistent effect on glucose, insulin, or C-reactive protein.”

“Lactate is a fuel and inter-organ signal, not merely a waste product. Human work links higher exercise lactate with circulating BDNF and selected acute executive-function outcomes, while animal and mechanistic studies support possible effects on neurogenesis.”

“In a randomized trial of 80 adults with overweight who usually slept fewer than 6.5 hours, counseling increased sleep by about 1.2 hours per night and reduced objectively measured energy intake by approximately 270 calories per day over two weeks.”

“Human trials suggest that alpha-lipoic acid can modestly improve selected lipid measures. A dose-response meta-analysis of 12 studies found reductions in total cholesterol, LDL cholesterol, and triglycerides across doses from 300 to 1,200 milligrams per day.”

“For people who begin in their seventies, Dr. Levine says exercise can still lower blood pressure, improve endothelial function, alter autonomic control, and raise VO2 max even when structural remodeling of the heart is limited.”

“Dr. Patrick also describes a proposed anti-metastatic mechanism: faster blood flow during vigorous exercise increases shear forces on circulating tumor cells, the cells that have left a primary tumor and entered the bloodstream.”
