Yes, banana helps you sleep better. Perhaps this is the reason why banana is considered as the fruit of the wise person and over 1 billion bananas are consumed annually! Banana has several health benefits and good sleep is one of them. Banana has high level of magnesium (which is a cure for insomnia, a disease related to sleeplessness & help you sleep longer as well as faster), potassium (which relaxes your muscles & regulate blood pressure) & Vitamin B6 (which is a kind of B vitamin which is vital for good sleep). So, make it a habit to grab a banana before going to bed & you will have a good sleep & productive day ahead!
