Sleep increases chromosome dynamics that clear out DNA damage accumulated during waking hours. A new study shows that sleep can heal DNA damage induced by many causes, including radiation, oxydative stress, . . . According to current state-of-the-art, sleep process is still far from being understood : “Nevertheless, the core cellular function of sleep is unknown, and there is no conserved molecular marker to define sleep across phylogeny“, “. . . however, why sleep has evolved and which fundamental ancestral functions it regulates, remain enigmatic.“
