Our addiction to screens in the evening directly impacts our immune health. Melatonin turns on our immune system and helps us deal with viruses, infections, and nascent cancers. When we see screens (and other artificial light) after sunset, it suppresses melatonin release. And no, a melatonin supplement is not quite like the real thing. The best way to keep your immune system strong is to get sunshine during the day (so your body can make vitamin D), and avoid screens in the evening (so you can secrete melatonin). Keep the terrain of your body vibrant, and then you don’t have to worry quite so much about exposure.
