In this video I talk about 10 everyday habits that quietly damage your health, metabolism, sleep, blood sugar, heart, lungs and long-term longevity. From vaping and alcohol to refined flour, poor sleep and ultra-processed foods, this video explains the science behind the modern lifestyle choices driving chronic disease and low energy.
As I always say on this channel, our health is largely determined by the "insignificant" things we do every day (good and bad).
In this video, I walk through the 10 things I personally avoid as an ER doctor, why I avoid them, what the evidence actually says, and which small changes make the biggest difference over decades rather than days.
What you’ll learn:
-Why vaping may not be as harmless as people think
-The hidden metabolic damage caused by liquid sugar
-Why constant snacking keeps insulin elevated
-How poor sleep changes your hormones and decision-making
-Why movement throughout the day matters more than one gym session
-The truth about refined flour and “healthy” snack foods
-Why circadian rhythm and sunlight may be one of the biggest health levers of all
