Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
A visual neuroscientist explains that blue light filters are ineffective for improving sleep, arguing that controlling total luminance (brightness) is more important than filtering specific wavelengths. The article debunks common myths about blue light and provides evidence-based alternatives for better sleep management, including practical advice for travelers dealing with jet lag.
