A 2024 study found that even dim light exposure during sleep can increase nighttime heart rate and blood sugar and reduce next-day insulin sensitivity. [PMC10851850]
Your sleep environment matters. Light disrupts circadian rhythms and signals your brain to stay alert when it should be in recovery mode.
Blackout curtains eliminate ambient light, protect melatonin production, and help you enter deeper, more restorative sleep. Better sleep means better metabolism, brain health, and longevity.
Your room isn’t fully optimized until it’s fully dark. Even @truedark glasses can give you some relief.
