Our Sleepiest Episode Yet...

If your child doesn't want to go to sleep, let me explain why they must...

Sleep does not start all at once.

It begins quietly, in ways your body already understands.

In this calming bedtime science episode, we explore the invisible, busy, and beautiful work your body does while you rest. From the gentle buildup of adenosine (sleep pressure) during the day to the brain’s nighttime work of cleaning, sorting memories, and preparing for dreams, this episode explains the science of falling asleep in a slow, soothing way.

Tonight, listeners will learn about:

• The Hourglass: Why you feel "heavy" at night due to the buildup of sleep pressure.

• The Nightly Tide: How the glymphatic system washes the brain clean while you dream.

• The Library: How your brain moves memories from the temporary vault (hippocampus) to permanent storage (cortex).

• The Cycles: The natural rhythm of sleep, from light drifting to deep repair and dreams.

Designed for kids, families, and adults, this episode blends real neuroscience with a peaceful rhythm that helps listeners relax and drift toward sleep without effort. It is perfect for bedtime listening, quiet evenings, and winding down after a long day.

🧪 Science Glossary for this Episode:

• Adenosine: The chemical signal that builds up while you are awake to tell your body it is time to rest.

• Sleep Spindles: Tiny bursts of brain activity that act like "shields," blocking out noise so you stay asleep.

• Circadian Rhythm: The internal clock that uses light to set your body's schedule.

There is nothing to do.Nothing to solve.Sleep is already beginning.
