Why put a cut lemon next to your bed at night?
I've come across this odd tradition of placing a cut lemon by one's bedside at night. Can you shed some light on the reasoning behind this practice? Is there any scientific basis to suggest that it could have a calming effect or improve sleep quality? Additionally, could it have any unintended consequences, such as attracting pests or affecting the air quality in the bedroom? I'm curious to understand the origins of this custom and if there's any truth to its purported benefits.
