Most animals placed under unnatural constant illumination have more difficulty sleeping due to decreased production of melatonin, a hormone that regulates sleep-wake cycles. Light exposure inhibits melatonin secretion from the pineal gland, disrupting circadian rhythms and leading to sleep disturbances. This disruption can negatively affect an animal's overall health and behavior, as proper sleep is essential for various physiological processes. Consequently, constant light can lead to increased stress and reduced well-being in these animals.
