Six breaths a minute, ten minutes, two or three times a day.

Konstantin Buteyko had high blood pressure himself. He developed the method looking for an answer to his own problem.
Lying in hospital, Buteyko noticed that dying patients were all breathing hard and deep. When he restricted his own breathing, his blood pressure fell.

Six breaths a minute, ten minutes, two or three times a day.
Keep the out-breath longer than the in-breath — four in, six to eight out.
This is educational information, not medical advice, and it does not replace treatment.
A good life starts with breathing well.
