Last night, Olsson snored for three minutes while I clocked in at six, a 4,000 percent decrease from ten days ago. Our sleep apnea, which disappeared the first night of nasal breathing, has remained nonexistent. My blood pressure this morning was 20 points lower than its highest point at the beginning of the experiment; on average I’ve dropped 10 points. My carbon dioxide levels consistently rose and were finally nudging toward the “super endurance” mark shared by Buteyko’s healthiest subjects.
