MEASURE YOUR NIGHT LIGHT LUX Lux is basically the brightness level of light shining on a specific area. You can get a cheap $9 lux meter off of my Amazon page from the link in my bio. This study shows the difference between a low or dim lux at night and a higher lux at night group. Compared with the Dim light at night group (less than 3 lux), the regular Light At Night group (more than 3 Lux) showed significantly higher body weight, body mass index, waist circumference, triglyceride levels and low-density lipoprotein cholesterol levels and showed significantly lower high-density lipoprotein cholesterol levels. These associations were independent of numerous potential confounders, including urinary melatonin excretion. Go get that meter and make sure your artificial light at night environment is spitting out less than 3 lux of light. Make it less than 1 to be safe.

It's time for you to see the light. Actually, its time for you to not see the light at night. In this study of elderly adults, artificial light at night of just over 5 LUX, increased their risk of diabetes by three times. Even at 3 lux, the results were significant. An on/off blinker light on one of your electronic devices can generate three lux of light. Continually exposing yourself to light at night is kind of like eating cupcakes 24/7. TLDR = Light at night is a cupcake. Put it down.

BUT MY ARTIFICIAL LIGHT AT NIGHT IS DIM BRO Unless its under ONE LUX which is similar to a the brightness of a full moon, NATURE DOESNT CARE, BRO. You are still being assessed a bad health penalty. Nights are supposed to be dark. Try to make them as dark as naturally possible. "Dim light in the evening (DLE) imposes an artificial extension of the solar day, increasing our alertness before bedtime, delaying melatonin timing and sleep onset, and increasing sleepiness in the next morning. Using laboratory mice as a model organism, we show that 2 wk of 4-h, 20-lux DLE postpones rest–activity rhythms, delays molecular rhythms in the brain and body, and reverses the diurnal pattern of short-term memory performance."

REMEMBER THIS NEXT TIME YOU HAVE YOUR LIGHTS BLASTING AT NIGHT.... Even DIM light at night disrupts your nocturnal circadian & melatonin rhythm. And... "Our research identified the importance of an intact nocturnal circadian melatonin anti-cancer signal in suppressing bone-metastatic breast tumor growth....dim light at night induces circadian disruption, which increases spread of bone metastatic breast cancer"
