New research suggests that humans have a unique ultradian gene program that operates on a 12-hour cycle. The study, published in npj Biology Timing Sleep, reveals that this natural rhythm is present in the human body and may play a crucial role in regulating sleep-wake cycles. The findings could lead to new insights into the mechanisms underlying human physiology and potentially inform the development of more effective treatments for sleep disorders.
