You've probably heard the advice: "Eat a banana before bed—it'll help you sleep!"
But is it true? Or could that innocent yellow fruit actually sabotage your rest?

Let's separate myth from science—so you can decide if this bedtime habit works for your body.
✅ Potential Benefits (When It Helps Sleep)
1. Natural Relaxation Support
Bananas contain:

Potassium (422mg): Reduces nighttime leg cramps and supports healthy blood pressure
Vitamin B6: Helps convert tryptophan → serotonin → melatonin (your sleep hormone)
🩺 Doctor insight: "For people with mild insomnia or muscle tension, a small banana 30–60 minutes before bed may ease the transition into sleep—but it's not a cure for clinical sleep disorders."
