Sleep timing
Affects chronotype and sleep duration
| Genotype | Impact | What it means |
|---|---|---|
| CC (Normal) | Normal | Standard circadian rhythm - flexible sleep timing. Keep consistent sleep/wake times and morning daylight. |
| CG (Carrier) | Low impact | Intermediate chronotype - moderate sensitivity to schedule changes. Keep regular sleep hours, get morning light, and avoid late screens and caffeine. |
| GG (Variant) | Moderate | Stronger chronotype tendency (earlier or later preference) - more vulnerable to sleep disruption from irregular schedules. Anchor consistent sleep/wake times, morning light, and a caffeine cut-off by early afternoon. |
