In Drosophila, distinct clocks assist in adapting to seasonal changes, influencing behaviors like reproduction. Mammalian rhythms are regulated by a master clock in the suprachiasmatic nucleus, demonstrating parallels across species.

It notes that blind individuals may face disruptions in these cycles. Melatonin supplements can enhance sleep quality and help with jet lag, generally without severe side effects.
