How Do Genetics Affect Circadian Rhythm Disorders?
Circadian rhythm disorders, such as delayed sleep phase disorder (DSPD) and advanced sleep phase disorder (ASPD), are often influenced by genetic factors. Mutations in genes like PER3 and CRY1 can disrupt the body's natural sleep-wake cycle, leading to these conditions. People with DSPD typically fall asleep and wake up much later than normal, while those with ASPD do so much earlier.
