Why 23 minutes?

23 minutes hits the sweet spot. Studies on meditation keep landing on the same range — about 20 to 25 minutes. That's long enough for your body to relax past the early fidgety stage, so the real benefits have time to build: sharper focus and a drop in cortisol, the body's main stress hormone. But it's still short enough to do every day without it becoming a chore.

According to UC Irvine researcher Dr. Gloria Mark, 23 minutes is the time it takes the human brain to fully regain deep focus after a single interruption, such as a phone notification or a quick question.
