Do you really know? Can a night owl ever become an early bird?
Dec 5, 2025
Discover the fascinating science behind chronotypes and how our genetics shape us into morning people or night owls. Learn about the societal challenges night owls face, often referred to as 'biological injustice.' Get tips on recognizing if you're out of sync with your natural rhythm, along with practical strategies to shift your sleep patterns. Finally, find out why fully transforming into an early bird might be unrealistic, but small adjustments can help you meet the day halfway. Dive into the intricacies of sleep and wakefulness!

Episode notes
Chronotype Is Largely Genetic
- Chronotype is an innate timing preference driven largely by genetics and circadian rhythm.
- About a quarter of people are morning types, a quarter are night owls, and the rest fall between.
Genes Map To Sleep Timing
- Large genetic studies have linked hundreds of genomic regions to sleep timing preferences.
- Our internal clock is partially written in our DNA, explaining familial patterns of night owls.
Early Schedules Create Biological Injustice
- Society schedules favor early risers, creating a mismatch for night owls forced into early routines.
- This misalignment causes chronic sleep debt and raises risks for mental and physical health problems.
