Taking a Dive: The Lowdown on Fainting - Imagine somebody is walking and suddenly falls down and is not responsive for a few minutes. A faint is a brief loss of responsiveness caused by a temporary reduction of the blood flow to the brain. It may be a reaction to pain, exhaustion, lack of food or emotional stress. Sometimes standing for a long time causes inactivity causes blood to pool in the legs, reducing the amount of blood reaching the brain👤. Fainting, medically known as syncope, is a sudden and temporary loss of consciousness due to a decrease in blood flow to the brain. It typically occurs when there's a drop in blood pressure or a lack of oxygen.🧠Dehydration and low blood sugar levels can also lead to fainting.
