Researchers recorded a fragment of speech from middle-aged women with rheumatoid arthritis and breast cancer.
They found that those who swore in the company of other people had increased depression. What more, those same people also lost social support.
The study has its limitations, as the sample. Swearing by women has an adverse effect on their social support. Particularly, societal norms dictate that women shouldn’t swear. The same study performed with young men may produce another result.
