Most births happen at night due to the body's natural circadian rhythms. Oxytocin levels, which play a crucial role in labor, tend to peak at night. Historically, giving birth at night may have offered an evolutionary advantage, allowing the mother to be in a safe, secluded place away from daytime predators.
