Amount of light exposure, specifically exposure to natural daylight, has been shown to affect the onset of puberty. The pineal gland in the brain produces the hormone melatonin, which regulates the body's natural sleep-wake cycle and is also involved in the onset of puberty. Natural daylight exposure can suppress the production of melatonin, leading to earlier onset of puberty.
