July's Health Factor: Sleep! 💤🛏️
To introduce you to just how important regular, unbroken, 7 to 9 hours per night of sleep is, we though we would direct you to an interview from Dr Rhonda Patrick with neuroscientist Dr. M Walker on FoundMyFitness.
Points of Interest:
🌛 Amyloid-beta is a toxic protein that creates plaque in the brain. It is directly involved in the development of Alzheimer's. Lack of sleep increases amyloid-beta, whose presence makes it difficult to sleep
🌛 It is thought that the amount of amyloid-beta in the brain predicts the severity of cognitive decline
🌛 It is thought that getting good quality sleep as we age can protect against Alzheimer's (since amyloid-beta levels would be lower)
🌛 The body has the lymphatic system for clearing toxins; the brain has the glymphatic system
🌛 The glymphatic system INCREASES 60% when we sleep, allowing the brain to flush waste and distribute nutrients
🌛 During deep sleep up to 40% of amyloid-beta is cleared from the brain. After 36 ours of sleep deprivation, amyloid-beta levels increase 25 to 30%.
For more on how sleep deprivation can increase loneliness, increase risk of disease, impair glucose regulation, promote obesity, and make student-life much more difficult, check out the full interview!
