“The pores on our feet are said to be the largest pores on our body, and some believe that spraying on the feet aids in getting the mineral into our blood system and lymphatics more directly/quickly,” Lauri Leadley, sleep expert and founder of Valley Sleep Center, tells Sleepopolis.
While this logic might make sense at first, there’s very limited research to suggest that spraying magnesium on your feet has any real sleep benefits
“There isn’t much evidence that spraying on the feet is more effective than an oral supplement. Given the information we have, it seems like nothing more than just another social media trend,” said Leadley.
