What are the hazards of sleeping with the lights on for children?

Patient's question:

No

Doctor's answer:

Because the human body is naturally sensitive to light, sleeping with the lights on affects sleep. The skin of the body accelerates metabolism when exposed to light. Sleep is for relaxation, but light stimulates the skin, defeating the purpose. Sleeping with the lights on affects sleep quality, weakens the immune system, and may even lead to the onset of cancer.
