Genetic Test Reveals Your Body Clock

Simple mouth swab can separate the larks from the owls

(Newser) – A simple mouth swab can tell scientists who's naturally meant to get up early and could forever free people who like a morning snooze from accusations of laziness, the Daily Telegraph reports. The newly developed test reveals the activity of the genes that regulate a person's body clock and identifies their natural sleeping and waking patterns.

Researchers say testing to tell if somebody is an early-rising "lark" or late-sleeping "owl" —or somewhere in between—could help prevent accidents caused by sleepy shift workers. Gaining information about a person's circadian rhythms could also help combat sleep disorders and make treatments such as chemotherapy, shown to work better at certain times of day, more effective.

Genes associated with sleep and wakefulness occur in different amounts at different times of day between individuals.
