Care about the world, sure. But you can’t fix a flood on another continent by refreshing at midnight.

Caring and consuming are not the same act, though they use the same feeling. Reading more about a disaster you cannot reach does nothing for anyone inside it, and the distress it produces is real, so you end the night depleted with nothing changed. Your concern is not the problem. Its aim is.

Pick the form your care can actually take, then close the tab. That might be money, or time, or a vote, or being useful to someone within reach of your hands. Set a limit on the reading, especially late, and let sleep be part of what keeps you able to help.
