While stigmata is typically thought of as a religious phenomenon, there are actually documented cases of people sweating blood. Blood coming through pores of skin is not necessarily supernatural in nature. Recent studies indicate what has been traditionally referred to as stigmata may actually be a medical condition known as hematohidrosis. Potentially caused by excessive stress, this may explain historical cases of stigmata.

The medical explanation for stigmata is still not widely studies or understood. It's a difficult condition to monitor and scientists are often hesitant to take claims seriously due to the religious and supernatural connections. Nevertheless, as more and more modern cases of stigmata are popping up, medical professionals are again taking an interest in the condition. If hematohidrosis is the cause, hopefully it can eventually be explained and cured.
