“The authors reported no changes in plasma concentrations of luteinizing hormone or cortisol and a significant decrease in plasma levels of the hormone leptin. Finally, they reported no differences in testosterone response between men of varying glucose tolerance or weight status.”

“The hypothalamic-pituitary-adrenal axis (i.e., gut-brain axis) is formed by neural and endocrine connections between the hypothalamis, a brain region that controls body temperature, hunger, and sleep; the pituitary gland, a endocrine organ in the brain that produces hormones; and the adrenal gland…”

“Prolonged exposure to artificial light disrupts circadian rhythms, the internal clocks that regulate daily cycles of hormones such as melatonin and cortisol. When these rhythms are disturbed, appetite, metabolism, and fat storage can be affected in ways that promote weight gain.”

“Regulating the amount of light in our environment is crucial for a good night's sleep and a good mood the next day. Habits such as using blue light-emitting electronics close to bedtime can reduce melatonin production by as much as 20 percent, impairing sleep.”

“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.”

Dr. Rhonda Patrick discusses child nutrition, osteoporosis, cholesterol-lowering supplements, her skincare routine, and fasting versus prioritizing protein.

“Biologically plausible strategies rooted in early medicine Against the backdrop of the devastating outcomes seen in some countries, where sudden and overwhelming spikes in case loads led to the unthinkable – a reversion to a primitive time when the modern medical system didn't exist at all – some have looked to the past for help in securing our future.”

Dr. Rhonda Patrick answers audience questions on various health, nutrition, and science topics in this Q&A session.

“paper Strengthening Individual Memories by Reactivating Them During Sleep A common thread between aging-associated loss of slow-wave sleep, accumulation of amyloid-beta, and impairment of hippocampal-dependent of memory The decline of deep, slow wave sleep begins much earlier in life than most people would expect, with losses occurring as early as the late 20s.”

“In Dr. Raison’s randomized, double-blind study published in JAMA in 2016, it was shown that a single session of whole-body hyperthermia (core body temperature was elevated to 38.5 C) produced a significant antidepressant effect in people with major depressive disorder compared to those who received a sham control.”
