Melatonin is a hormone involved in many of the body’s functions, but it is especially important for the sleep-wake cycle. The body’s daily rhythm influences the sleep-wake cycle and this determines the amount of melatonin produced. Melatonin levels naturally increase in the late afternoon and drop in the morning, helping you to develop a healthy and habitual sleep pattern. However, blue light from electronic devices disrupts the biosynthesis of melatonin, making a bad night’s sleep an increasingly common complaint in recent years. Taking melatonin supplements can support a longer and more restful sleep, even if the person is stressed or exposed to blue light. Nordic CBD therefore uses melatonin to shorten the sleep-latency period, allowing for the faster onset of sleep.
