In 2019, Dr. Michael Weedon of the University of Exeter Medical School in the United Kingdom and colleagues analyzed genomic information from nearly 700,000 people and correlated it with the wake time preferences these participants answered on questionnaires. In the end, this large-scale genome-wide association analysis (GWAS) found 351 related gene loci that had not been previously identified. In short, people's circadian rhythms are affected by genetic variation, and whether they go to bed early and get up early or go to bed late and get up late is an innate tendency.
