What the headline saysBlue Light and Sleep: Do Screens Really Matter?
Blue light from screens can affect sleep, but its impact is often overstated compared to other factors. What time you use screens, what you do on them, and your overall sleep habits matter more. Simple changes to your evening routine are likely to be more effective than blue light glasses alone.

How we read a health headline
Most scary or miraculous health claims are not lies. They are real findings stretched past what they can carry. We try to put them back in proportion.
- What kind of evidence is it?
- A lab dish, a mouse, a survey of eating habits and a randomized trial in people answer very different questions.
- Risk compared to what?
- "Doubles your risk" can mean a big change or a tiny one. The starting point matters more than the multiplier.
- Does it fit the wider picture?
- One result rarely overturns a large, consistent body of research. We look at where the evidence points overall.
- Who is it true for?
- Advice that helps one group can be irrelevant, or wrong, for another. We say who a finding applies to.
