What is sleep?
Sleep is an active, carefully organized process. Through the night you cycle through lighter stages, deep restorative sleep and dreaming REM sleep, each with its own role in memory, repair and emotional balance. The timing of sleep is guided by your circadian rhythm, an internal clock of roughly a day that responds to light, meals and activity. A second force, sleep pressure, builds the longer you stay awake.
How your genes play a role
Your circadian clock runs on a set of genes that switch each other on and off in a daily loop. Variants in these clock genes may shift your natural timing earlier or later, which is part of why people have different chronotypes. Other genes influence how you respond to melatonin, the hormone of darkness, and to brain chemicals that promote calm and wakefulness.
When your schedule works with your natural rhythm, sleep often feels easier and days feel steadier. Understanding whether you may lean toward being a morning lark or a night owl can help you plan work, exercise and wind down routines with less friction. It may also explain why certain habits, like late screens or irregular hours, affect you more than others.
What your report shows
Your Sleep results are explained in plain language in your private EvoDNA account, alongside the other areas in your kit.
- Your chronotypeWhether your genes may lean toward earlier or later natural sleep timing.
- Clock stabilityHow variants in core clock genes may shape the strength of your daily rhythm.
- Melatonin responseHow your melatonin receptor genes may influence your response to darkness.
- Calm and alertnessVariants in brain chemistry genes linked to winding down and staying alert.
| Gene | What it does | Result |
|---|---|---|
| PER3 | A core clock gene whose variants are linked to… | Typical |
| PER2 | Helps keep your internal clock in time, and rare… | Moderate effect |
| CLOCK | Works with BMAL1 to switch on the daily cycle… | Typical |
Each result comes with a plain-language explanation and practical points to discuss with your clinician.

Genes we analyze
| Gene | Role |
|---|---|
| PER3 | A core clock gene whose variants are linked to morning or evening preference and how you handle lost sleep. |
| PER2 | Helps keep your internal clock in time, and rare variants are known to shift sleep much earlier. |
| CLOCK | Works with BMAL1 to switch on the daily cycle of clock genes in your cells. |
| CRY1 | Acts as a brake in the circadian loop, and certain variants are linked to a later natural sleep timing. |
| MTNR1B | Codes for a melatonin receptor that helps your body read the signal of nighttime. |
Full panel: 14 genes
PER1, PER2, PER3, CLOCK, BMAL1, CRY1, CRY2, MTNR1A, MTNR1B, COMT, MAOA, BDNF, 5HT1A, GABA
Putting results to use
Many people use their results as a starting point for conversations with their clinician about:
Getting daylight soon after waking is often discussed as a way to anchor your clock.
Keeping similar sleep and wake times, even on weekends, may help your rhythm stay steady.
Lowering bright light and screens before bed can help melatonin rise naturally.
Many people find that keeping coffee to the earlier part of the day supports better sleep.
Questions
Am I genetically a night owl?
Your genes may lean you toward an earlier or later rhythm. Light exposure, age and habits also play a large role, so your chronotype can shift over life.
Can my results explain poor sleep?
They can add context about your natural timing and sensitivities. Persistent sleep problems have many causes, so it is worth discussing them with a clinician.
Should I take melatonin based on my results?
Please talk with your clinician before starting any supplement. Your results can be a useful part of that conversation, but they are not a prescription.
