Verified step by step guidance1
Understand the role of melatonin: Melatonin is a hormone produced by the pineal gland in the brain, primarily responsible for regulating sleep-wake cycles.
Recognize the effect of light on melatonin: Exposure to light, particularly blue light, can inhibit the production of melatonin, making it harder to fall asleep.
Identify sources of blue light: Blue light is emitted by electronic screens such as those on phones, tablets, and computers, which can interfere with melatonin production.
Differentiate between the hormones: Cortisol, adrenaline, and insulin are not primarily involved in the sleep-wake cycle regulation like melatonin is.
Conclude that blue light suppresses melatonin: Based on the understanding of melatonin's role and the effect of blue light, it is clear that blue light from screens suppresses melatonin production.
