According to this article on ScienceDirect.com there’s been a link made between bright lights at night and cancer. Turns out bright lights in the early morning hours trigger blue receptors in they eye which signal the hypothalamus to suppress melatonin production in the pineal gland.
Basically, bright lights with blue content will signal the body to produce less melatonin, which can allow cancer to grow more rapidly.
That’s pretty alarming.
