ELI5: How does doomscrolling affect the human brain and mental health?

Doomscrolling tricks your brain into thinking you are in constant danger, which makes you feel exhausted, worried, and unhappy.

Imagine your brain has a tiny, built-in smoke alarm called the amygdala. A long time ago, this alarm helped humans survive by warning them about real dangers, like a tiger hiding in the bushes. Today, when you sit on the couch and endlessly scroll through bad news, sad stories, and scary videos on your phone, that little alarm thinks the tiger is right inside your living room.

Every time you read something alarming, your body sends out stress hormones, like cortisol and adrenaline. In everyday life, this causes several things to happen:

• Constant worry: Even though you are safe in your bed, your heart might beat faster and your stomach might feel tight, leaving you in a state of anxiety.
• The endless loop: You keep scrolling because your brain hopes the next swipe will bring good news or relief, but it almost never does.
• Trouble sleeping: When you fill your mind with scary thoughts right before bed, your brain stays on high alert, making it very hard to fall asleep.
• Brain fog and bad moods: Over time, dealing with all this fake danger tires your brain out, making you grumpy, sad, and unable to focus on homework, family, or playtime.

The best way to turn off that false smoke alarm is simple: put the phone away, step outside, take a deep breath, and remind your brain that you are safe right now.
