00:00Could your bedroom lights be damaging your heart?
00:02New research says yes.
00:04Even small amounts of light at night could silently raise your risk of heart disease.
00:08In a groundbreaking study, scientists found that artificial light exposure at night ramps
00:13up stress in your brain and inflames your arteries—a deadly combo for your heart.
00:18Using brain scans and satellite data, they discovered a clear pattern.
00:22More light at night equals more brain stress and artery inflammation.
00:26The result? Up to a 35% higher risk of heart disease in just 5 years and a 22% increase
00:32over 10.
00:34And this isn't just about city street lights.
00:36Even your bedroom lamp or late night screen time could be doing harm.
00:40Here's why.
00:41Your brain sees artificial light as a stress signal.
00:44It fires up your nervous system, triggers inflammation in your blood vessels, and over time, this could
00:49lead to heart attacks or strokes.
00:52Experts say the fix is simple.
00:54Keep your room dark.
00:55Avoid screens before bed.
00:57And if you can, lobby for smarter street lighting in your neighborhood.
01:01This study might just change how we see light—not as harmless glow, but a hidden health threat
01:06lurking in the night.
01:07So next time you leave a light on, ask yourself, is it worth your heart?
