In 2017, a scientific study took place which found that calligraphy significantly reduced heart rate, respiratory rate, systolic blood pressure, as well as self-reported state-trait anxiety levels, depression and stress levels in breast cancer patients who received an eight-90 minute Chinese calligraphy intervention.
Two hypotheses were supported by the results of the research: 1) There was a physiological slowing effect in blood pressure, heart rate and respiratory rate among breast cancer patients after the intervention; 2) Breast cancer patients had reduced scores on self-reported measures on anxiety and comorbid depression levels after the intervention.
