Eating a banana before bed is a common habit—some swear by it for better sleep, while others worry it might cause weight gain or digestive issues. So, what does science say?
The truth? For most people, a banana before bed is not only safe—it may actually support restful sleep, thanks to its unique blend of nutrients. Here’s what really happens:
🌙 1. May Help You Fall Asleep Faster
Bananas contain three key sleep-supporting compounds:
- Tryptophan: An amino acid your body converts into serotonin and melatonin—hormones that regulate sleep.
- Magnesium: A mineral that helps relax muscles and calm the nervous system.
- Potassium: Supports muscle relaxation and may reduce nighttime cramps.
📌 While the amounts are modest, they work synergistically—especially when paired with a balanced evening routine.
