Learn moreSleeping with the Light On: What It Does to Your Heart
Sleeping with the light on doesn't just disturb your sleep -- research from Northwestern University shows it raises heart rate, disrupts autonomic balance, and increases insulin resistance after a single night. Here's what the science says and how to protect your cardiovascular health.
Learn moreArtificial Light at Night: The Hidden Link to Obesity and Cancer Risk
Artificial light at night is linked to obesity and cancer risk through melatonin suppression and circadian disruption. Learn what the NIH Sister Study and IARC classification reveal -- and how a genuinely dark bedroom can make a measurable difference.
Learn moreScreen Time at Night: What It's Actually Doing to Your Sleep (And What to Do About It)
Screens before bed affect sleep through two separate mechanisms: blue light photochemistry and cognitive arousal. Learn what the research actually shows, whether night mode helps, and the overlooked bedroom light problem that screens often get blamed for.
Learn moreLight While You Sleep and Type 2 Diabetes: What the Research Shows
Research from Northwestern University and Flinders University shows that sleeping in a lit room raises insulin resistance after just one night -- and increases type 2 diabetes risk by up to 53% long-term. Here's what the science says and how to protect your metabolic health with better bedroom darkness.
