For a long time, I had a hard time sleeping. We can chock it up to bad food late at night, too many screens before bed, and stress.

I found it incredibly difficult to shut my brain down and give it a break at night. After weeks of not being able to sleep a full night, a friend of mine told me about the "4-7-8" breathing trick.

But what is that?

This method was developed by a wellness practitioner, Harvard-educated Dr. Andrew Weil, who studies meditation, breathing, and how it can be used to counteract stress.
