Shawn Stevenson on 10 Ways to Sleep Better Tonight - with Lewis Howes

Brain Health

Shawn Stevenson explains the critical role of the glymphatic system in brain health. This system, which is ten times more active during sleep, helps eliminate waste from the brain, potentially preventing conditions like Alzheimer's 1. He also highlights the importance of human growth hormone, often called the "youth hormone," which is secreted during sleep and aids in muscle growth and anti-aging 2.

Your brain cells actually shrink about 60% while you're asleep to make more room to eliminate waste.

Environmental Factors

Lewis Howes and Shawn discuss the impact of environmental factors on sleep quality. They emphasize the importance of avoiding screens before bedtime, as the blue light emitted can suppress melatonin production, leading to poor sleep quality 3. Additionally, they stress the need for a pitch-black sleep environment to prevent light pollution from disrupting sleep cycles 4.

Just 2 hours of device usage before bed was enough to suppress melatonin secretion.
