Think Night Mode Protects Your Sleep? Think Again.

We’ve been told that blue light at night disrupts sleep—so tech companies introduced Night Mode and “warmer” screen tones. But science says this might not be enough.

The 3 Problems with Night Mode

1. It only reduces blue light, NOT screen stimulation.

The brain still registers bright screens as daytime—even with a warmer tone.

2. It doesn’t block enough blue light.

Studies show phone Night Mode only blocks 10-30% of blue light, while red-tinted glasses block 90%+.

3. It does NOTHING to prevent dopamine spikes from scrolling.

Your phone’s notifications, social media, and texts still trigger cortisol (stress hormone) and dopamine hits that prevent deep sleep.

The Fix? Do This Instead
✔️ Use Red-Tinted Blue Light Blocking Glasses After 7PM
✔️ Reduce ALL screen brightness—not just Night Mode
✔️ Replace late-night scrolling with audiobooks or podcasts
