“For example, disruption in deep sleep is highly pronounced in people with Alzheimer's disease and typically precedes diagnosis. Glymphatic activation has also been shown to play a key role in the transport of biomarkers of traumatic brain injury (TBI).”

“After the sleep-deprived night, the participants' anxiety levels were increased after viewing the events. When the participants had a full night of sleep, however, their anxiety levels were decreased, especially for those who experienced deep sleep.”

“The accumulation of visceral fat is linked to type 2 diabetes, insulin resistance, inflammatory diseases, certain types of cancer, cardiovascular disease, and other obesity-related conditions. Findings from a recent study suggest that not getting enough sleep increases the risk of developing excess visceral fat.”

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

“Dr. Patrick also describes increasing her own routine intake from 5 to 10 grams as she became more interested in its potential brain effects. A small double-blind crossover study tested a single 0.35-gram-per-kilogram dose during approximately 21 hours of sleep deprivation.”

“Poor sleep negatively affects metabolism, impairing glucose tolerance and increasing the risk of developing type 2 diabetes. Findings from a recent study indicate that HIIT compensates for the harmful effects of sleep loss on glucose tolerance.”

“A later cohort of 13,994 men and women also found lower dementia incidence among more frequent sauna users. Dr. Patrick connects these findings with vascular function, sleep, and preserving physical capacity when normal training is limited.”

“Sleep deprivation reduces testosterone levels in young men. Just one week of sleep deprivation reduces young men's testosterone levels by as much as 15 percent, according to a 2011 study. Missing out on sleep worsened the young men's mood and overall energy levels, too.”

“People who engaged in strength exercises were more likely to report better sleep, with the strongest improvement observed across all comparisons. Aerobic activity also helped but wasn't as effective, and combined exercise had a more modest benefit.”

“Sleep deprivation markedly increased reactive oxygen species in the animals' guts. After ending the sleep deprivation, the reactive oxygen species levels slowly decreased, nearly returning to their baseline levels.”
