There’s something meditation devotees have always noticed about meditation—it’s a real stress-reducer.

And now, there is a study that backs them up.

A UC Davis study shows that “focusing on the present — or being mindful — can lower levels of the stress hormone cortisol.”

In the study:

[i]ndividuals who scored high on the mindfulness questionnaire also had low levels in cortisol, both before and after the retreat. Subjects whose mindfulness score increased after the retreat also showed a decrease in cortisol.

Finally, it’s been proven that stress can literally be reduced by meditation. It also explains why doctors, especially cardiologists, are asking their patients to embrace meditation as a form of stress treatment.

So if you’re stressed, if you find yourself constantly on the edge, if your loved ones are constantly telling you to calm down–give meditation a try.
