“A recent study in mice found that probiotics alleviated sleep-deprivation-induced cognitive impairments. Researchers fed sleep-deprived mice a probiotic containing Bifidobacterium breve and subjected them to memory and behavioral tests.”

“These findings suggest that low intake of macro- and micronutrients impairs sleep in adults and suggest that dietary supplements can compensate for dietary shortcomings. Learn about other dietary components that influence sleep duration and quality in this clip featuring Dr. Matthew Walker.”

“Participants who had decaffeinated coffee during sleep restriction had more gray matter than those who had caffeinated coffee. Participants with lower baseline adenosine receptor availability generally demonstrated greater gray matter losses.”

“However, students who experienced poor quality sleep performed worse on recall tests than those with good quality sleep. These findings suggest that targeted memory reactivation enhances memory consolidation, especially in the setting of deep, good quality sleep.”

“Dr. Patrick describes her own 10-gram baseline and occasional 20- to 25-gram use during travel or sleep loss as a personal extrapolation. This clip is excerpted, with permission, from Dr. Rhonda Patrick’s appearance on the Jack Neel Podcast.”

“Researchers examined brain activity, hormone levels, and eating behavior under different sleep conditions in mice and humans. They identified a previously unknown hormone, which they named raptin, and tracked where and when it was released.”

“After a 3-day washout period, the procedure was repeated with the participants who received the placebo taking the yeast and vice versa. Throughout the study, each participant completed a questionnaire to assess the subjective measures of their sleep quality.”

“Sleep has profound effects on immune function, driving T-cell migration to lymph nodes – the primary site of adaptive immunity initiation. However, scientists don't fully understand the mechanisms that underlie links between sleep and immunity.”

“Brains with the largest amount of neurons (over 6,000) belonged to people with longer, uninterrupted sleep. > Another key finding from the study: The link between fewer neurons and less sleep was even more pronounced in people who had died with Alzheimer's disease.”

“Sleep loss may also interfere with protein synthesis, driving skeletal muscle losses, a risk factor for obesity, type 2 diabetes, and frailty. Authors of a recent report measured the effects of sleep deprivation on muscle protein synthesis.”
