“In a small trial involving adults with obesity, a ketone monoester improved one processing-speed task and selected brain blood-flow measures, providing an early signal for further research. Temperature can also shape alertness and sleep preparation.”

“Dr. Patrick starts with the Finnish observational evidence: frequent sauna use and sessions longer than 19 minutes were associated with lower cardiovascular mortality in middle-aged men. That evidence informs her routine, but it does not make her temperature, duration, or frequency a universal prescription.”

“Manipulating the core body temperature through hot baths, showers, or saunas – which can have a paradoxical effect on reducing core body temperature – can have dramatic effects on our ability to fall asleep.”

“In this clip from Q&A #70, Dr. Rhonda Patrick organizes cancer prevention around the largest modifiable foundations: avoid tobacco, maintain a healthy body composition, and stay physically active.”

“In a small crossover trial involving people with insulin resistance, six one-minute intense intervals performed before the three main meals improved daily glucose control compared with one continuous 30-minute session.”

“Practicing healthy light exposure habits — seeking bright light in the morning and avoiding it in the evening — is crucial. When we eat also plays a role, and eating too close to bedtime disrupts sleep and shifts circadian timing over the next few days.”

“Dr. Brooks's exact practice of waking 96 minutes before dawn comes from the Vedic concept of Brahma Muhurta rather than a tested clinical protocol. Creatine may provide modest cognitive benefits in some settings, although results in healthy adults are mixed.”

“Dr. Schoenfeld says the situation is likely more complex and nuanced. For example, a marathon runner will have difficulty with hypertrophy, probably due to overtraining rather than intracellular signaling negatively affecting muscle development.”

“A growing body of scientific evidence suggests that there's a correlation between nutrition, exercise, sleep, and stress management and having longer telomeres. Identifying the mechanisms that drive these correlations has proven challenging, but a few candidates stand out, including improvements in immune function and metabolic health.”

In this clip, Dr. Patrick explains how intense exercise beneficially alters tryptophan and kynurenine metabolism in a way that may benefit depression.
