Sleep Duration

Sleep Patterns

Sleep duration refers to how many hours a person typically sleeps in a 24-hour period. Most adults function best on 7 to 9 hours.

GWAS work has identified variants in genes that influence circadian rhythm and sleep regulation that contribute to differences in habitual sleep length.

This result reflects research-level variation in sleep biology and is not a recommended sleep amount for any individual.

Work schedule, family demands, stress, light exposure, caffeine, screen use, and health all influence how much someone actually sleeps.

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.
