Why Your Brain Won’t Shut Off at Night
Do you lie in bed, replaying conversations, worrying about tomorrow, or obsessing over past mistakes? You’re not alone. Overthinking at night is a common problem—but it’s not hopeless.
Key Stats:
- 73% of adults admit to overthinking at night (National Sleep Foundation)
- Nighttime overthinking is linked to higher cortisol levels (stress hormone)
- The brain’s default mode network (responsible for self-reflection) becomes hyperactive when we’re tired
The good news? You can train your brain to stop overthinking at night—starting tonight.
Why We Overthink at Night (The Science)
1. The “Bedtime Brain Dump” Phenomenon
When you finally lie down, your brain processes the day’s events. Without distractions, thoughts spiral.
🔬 A 2022 Harvard study found that people who journal before bed reduce overthinking by 40%
2. Cortisol + Melatonin Imbalance
Stress keeps cortisol high, while darkness should trigger melatonin (sleep hormone). Overthinking disrupts this balance.
3. The “Problem-Solving Trap”
Your brain believes nighttime is the perfect moment to “fix” everything—but it’s the worst time for rational thinking.
