What's Your Sleep Story?
Journey through the mysteries of sleep with Luna, your celestial guide to understanding rest and recovery
Unlock the Science Behind Your Sleep
Your sleep journey doesn’t end when you close your eyes—it transforms. As you rest, heart rate patterns shift, hormones regulate, and your body recalibrates for the next day. Scroll down to explore how these vital trends evolve during and after sleep, shaping your well-being.
Heart Rate Analysis
Understanding your body's rhythm between sleep and wakefulness
Heart Rate Insights
Your heart doesn't just beat at a constant pace—it follows a dynamic rhythm influenced by sleep stages, activity, and recovery processes.
Hormone Balance
How cortisol and melatonin orchestrate your sleep-wake cycle
Hormone Dynamics
Two key hormones work in harmony to regulate your sleep cycle: cortisol for alertness and melatonin for rest.
Cortisol (ng/mL)
The alertness hormone that peaks in the morning to kickstart your day
Melatonin (pg/mL)
The sleep hormone that rises before bedtime and fades upon waking
Note: Cortisol measures in nanograms (1,000x larger than picograms), reflecting its higher concentration needed for metabolic regulation.
Connecting Sleep Physiology to Personalized Insights
We've explored how heart rate changes between sleep and wakefulness, providing insights into your body's recovery process. But sleep quality isn't just about heart rate, it's also driven by hormonal fluctuations like cortisol and melatonin. Cortisol helps you wake up and stay alert, while melatonin signals when it's time to sleep. The delicate balance between these hormones can impact how restful your night truly is.
To take sleep analysis a step further, we introduce the Sleep Quiz which is a science-backed tool that predicts stress hormone levels and sleep quality based on your individual patterns. This predictor also matches you with a sleeper most similar to you, helping you compare habits and uncover personalized insights to optimize your rest.
