Genes influence susceptibility to internal clock disorders

A study led by the Medical University of Vienna has revealed that vulnerability to disruptions in the body's internal clock is not caused by a single factor but rather by an interplay of various traits, some of which have a genetic basis. The internal clock governs numerous bodily processes, including cycles of wakefulness and fatigue, operating on an approximate 24-hour rhythm.

When this internal clock becomes desynchronized, it can lead to negative health consequences. The research indicates that an individual's susceptibility to such disruptions is influenced by a combination of genetic factors and other inherited characteristics.

While the study highlights the genetic component, it emphasizes that it is the interaction of multiple genetic predispositions that contributes to an increased risk of circadian imbalance. This suggests a complex genetic architecture underlying the regulation of our internal biological rhythms.
