Funerals are particularly tough and often tearful affairs. Multiple reports of fainting have been made at recent ceremonies held in the wake of The Queen's death.
So, what are the potential triggers for fainting at a funeral? The question of why people faint at funerals has long puzzled sociologists.
The health service suggests that standing up too quickly may be a sign of low blood pressure, and that dehydration, hunger, heat, and pain may all play roles.
According to Dr. Boon Lim, consultant cardiologist and syncope specialist, another possible cause, which is relevant to funerals, is "being upright and still for prolonged periods."
'Fainting can also occur during an extreme emotional stimulus, such as feeling very sad or fearful,' explains Dr. Boon Lim, who also created the website Stop Fainting.
Bereavement's strong emotions can cause fainting. Extremely negative news or events can also trigger similar episodes.
People who are having blood drawn frequently faint. People in these situations may pass out from fear of the medical procedure even before the needle is punctured.
It's important to get checked out if you faint frequently because it could be a sign of a serious health issue like low blood pressure or heart disease.
