yawn is a spontaneous process in the body, it is not associated with external signs, therefore it cannot be a precursor of a heart attack or stroke. As RBC writes, the head of the Russian service “Stop-stool”, Doctor of Medical Sciences, Professor Evgeny Shirokov.
“One person in the group yawns, and people next to him most often begin to yawn. This suggests that if it were a mechanism associated with individual circulatory disorders, he could not be transmitted to other people,” said Russian specialist.
According to him, the nature of this phenomenon is still not clarified, it can occur for various reasons, reflexively and in relation to nutrition. For example, a person overwhelms the yawning after abundant food or with drowsiness, and sometimes without visible circumstances.
Associate Professor of the Neurology Department and Neurosurgery of the Kursk Medical University Rustem Gaifutdinov also stated that the yawa is not considered as a precursor of a heart attack or stroke. He added that a sign of acute circulatory disorder is headache, dizziness, weakness, worsening speech, movements or vision.
