Why Blue Light Keeps You Awake at Night
Think blue light is natural? It’s actually a modern invention. Before electricity, we slept when the sun went down. Our bodies knew rest. Then came Edison. Incandescent bulbs were warm, but later tech changed everything. LEDs are efficient, but their raw emission is intensely blue. Now our screens flood our brains with wake-up signals at midnight. Turn on Night Shift mode tonight. Your sleep will thank you.
