Neurons in the night

**Verse 1:** When the day turns dark and the night takes hold, There’s a clock in your brain that’s ancient and old. The suprachiasmatic nucleus guides the way, Telling every cell it’s time to end the day. Melatonin’s rising as the light fades out, Telling your body what sleep’s all about. Synapses quiet, neurons start to rest, Your brain begins its nightly quest. **Chorus:** Let the REM waves roll, let the delta take control, In the science of sleep, where the body and mind console. Neurons fire, in the brain’s deep spire, As the biology of sleep takes you higher and higher. **Verse 2:** Stage 1’s the gateway, a soft, gentle drift, Where consciousness fades, and the muscles shift. Stage 2’s the shield, where spindles protect, Neurons firing in a rhythmic connect. In Stage 3, the slow waves reign, Your body’s in repair, fixing the strain. Growth hormone flows, the tissues renew, In the deepest sleep, where the body’s true. **Chorus:** Let the REM waves roll, let the delta take control, In the science of sleep, where the body and mind console. Neurons fire, in the brain’s deep spire, As the biology of sleep takes you higher and higher. **Bridge:** Adenosine’s rising, pushing you down, In the world of sleep, where silence drowns. But as the night ends, cortisol spikes, Waking you up to the morning light. **Outro:** So close your eyes, let the biology flow, Feel the rhythm of life as you softly go. Into the depths where the body’s at peace, In the science of sleep, find your release.
