研究显示,开灯睡觉的儿童或者生物钟自然睡眠模式受人造光线干扰的人,患癌症的可能性比平常人要大。人造光线对人体的破坏性影响会降低人体降黑素的水平。降黑素通常会在夜晚增加,可以保护细胞免受损伤,否则细胞很容易受到肿瘤的破坏。 Studies have shown that children who turn on the lights or who are disturbed by artificial light in their natural sleep mode have a higher chance of developing cancer than normal people. Destructive effects of artificial light on the human body will reduce the body’s level of melanin. Melanin, which usually increases at night, protects cells from damage that could otherwise be damaged by the tumor.
