Sleep quality refers to how restorative sleep feels, including how easily someone falls asleep, how often they wake, and how rested they feel.
GWAS work has identified variants linked to insomnia traits, sleep continuity, and arousal regulation.
This result reflects research-level variation in sleep biology and is not a sleep study or a clinical diagnosis of insomnia.
Sleep environment, schedule consistency, stress, caffeine, alcohol, screens, exercise, and underlying health also strongly affect real sleep quality.

DNA Genics reports genotypes based on the 'positive' strand of the human genome reference sequence (build 37/HG19). Other companies may use the opposite strand, so genotypes may need conversion for comparison.
The following peer-reviewed scientific studies support the genetic associations analyzed in this report.
