“From THC, CBD, alcohol, caffeine, and nicotine to melatonin, magnesium, glycine, and calming botanicals, these compounds can either support restorative sleep or subtly hijack it, changing REM, deep sleep, and circadian timing in ways we often do not feel until the next day.”
“In this Aliquot, sleep scientist Dr. Michael Grandner explains why sleep apnea is so often missed, how these nightly breathing disturbances affect the body, and which treatments can meaningfully improve sleep and long-term health.”
“The different stages of sleep provide crucial periods during which the body recalibrates to promote both mental and physical well-being. In this clip, Dr. Matthew Walker describes how the different stages of sleep influence emotional and cardiovascular health.”
“Shift work creates a chronic disruption of circadian rhythms that affects sleep, metabolism, decision-making, and long-term health, often in ways people don't recognize until years later. In this Aliquot, joined by Drs.”
“These changes increase infection risk, weaken vaccine responses, and reduce early cancer surveillance. Yet immune aging is not fixed. Movement, sleep, stress regulation, temperature exposure, and nutrition shape immune cell balance and inflammatory activity over time.”
“Insulin-like growth factor-1, or IGF-1 for short, is a protein that plays critical roles in major growth pathways in the human body. It influences nearly every tissue in the body, especially developmental growth, skeletal muscle and neurons.”
“Coffee consumption is associated with protection from several chronic diseases. Coffee's beneficial effects may stem from its ability to induce autophagy; however, other evidence points to the benefits of caffeine, which can reset the body's internal clocks in the morning.”
“Poor sleep reduces the body's insulin sensitivity and changes a person's appetite, increasing the preference for high carbohydrate foods like pizza, pasta, and sweets. Lack of sleep also alters the gut microbiota and impairs immunity, putting us at risk for developing acute illnesses like colds and flu.”
“The decline of deep sleep begins early in life, nearly disappears by age 80, increasing the risk for Alzheimer's disease. These Aliquot segments feature Dr. Charles Raison, a professor of psychiatry, and Dr. Matthew Walker, a professor of neuroscience and psychology.”
“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.”
