It's time to wake up to the importance of sleep. Groundbreaking 2013 research shows that our brain cells shrink while we sleep, allowing a cleansing fluid to rinse away toxic proteins that lead to Alzheimer's. Sleep also "backs up" important memories into the brain's cortex for long-term storage. Learn about how sleep changes as we age, and why getting enough sleep is so critical for health.
K-12 & Education
It's a competitive world in which science, technology, mathematics and engineering impact our economy, health, societal well-being and policy. Scientists, engineers and educators provide the ideas and knowledge base for U.S. leadership in science and engineering. Learning how people learn, while also supporting the very best ideas and students are also essential goals in today's changing world.
Be honest: Do you ever brag about how little sleep you get? If so, you're not alone. Humans are the only species that seems to deliberately deprive themselves of sleep. But if you've ever uttered a phrase like, "I'll sleep when I'm dead," scientists say it's time for a wake-up call.
