- Perfectionistic analysis: Wanting things to be “perfect”
before acting
- Decision paralysis: Fear of choosing the wrong option
- Hypervigilance: Overthinking people’s reactions
or behavior

Catastrophizing (Worst-Case Thinking)
Jumping to the most negative possible conclusion.
3.
Perfectionistic Overthinking
Feeling afraid to make decisions unless outcomes are certain.
4.

🧬 Causes of Overthinking
Overthinking is usually triggered by a mix of psychological,
environmental, and biological factors.
1.
Stress and High Responsibility
People with demanding lifestyles, academic pressure, or emotional burdens
tend to analyze too much.
2.
Childhood Experiences
Strict parenting, criticism, or chaotic environments can lead to
hypervigilant minds.
3.
Perfectionism
Setting unrealistically high standards creates fear-based thinking.
4.
Fear of Failure or Rejection
The mind overthinks to “prevent” pain—but ends up creating more stress.
5.
Anxiety Disorders
Generalized anxiety, social anxiety, and OCD often include overthinking
patterns.
6.
Trauma or Emotional Hurt
The brain stays alert, replaying past events as a survival mechanism.
7.
Biological Factors
Hormonal imbalance, high cortisol, low serotonin, or chronic sleep
deprivation can worsen rumination.

🌙 How to Stop Overthinking at Night and Sleep
Better
Nighttime overthinking is extremely common because the brain has fewer
distractions. Here’s how to break the cycle:
⭐ 1. Build a Pre-Sleep Routine
Dim lights, disconnect from social media, stretch, and avoid heavy
conversations.
⭐ 2. 10-Minute Brain Dump
Write all thoughts before bed to clear mental clutter.
⭐ 3. The “Parking Lot” Technique
Tell your brain: “I will return to these thoughts tomorrow at 10 AM.”
⭐ 4. 4-7-8 Breathing
A deep breathing technique proven to reduce night anxiety and induce
sleep.
⭐ 5. Muscle Relaxation
Tense each muscle for 5 seconds → then release.
This interrupts mental spiraling.
⭐ 6. Reduce Phone Use at Night
Blue light increases cortisol and overstimulates the brain.
⭐ 7. Use Calming Audio
Rain sounds, white noise, Quran recitation, or soft music help distract
the mind.
⭐ 8. Improve Your Sleep Environment
Dark, cool, clean, and quiet rooms help the brain relax.
