Did you know that being exposed to unnatural light at night may be a cancer risk? Our sleep hormone, melatonin is suppressed by exposure at night to artificial light, especially the blue light of screen devices. Research has found that a reduction of melatonin at night can lead to suppression of the immune system and its role in detecting and fighting abnormal cells.
Turn your screen devices off an hour or two before bedtime. Keep your bedroom dark: Turn off any night lights or TVs in your bedroom, and keep smartphones and other screen devices out of your bedroom.
