      When someone faints (syncope), it’s usually because of a drop in blood pressure, which reduces blood flow and oxygen to the brain. Normally you regain consciousness pretty quickly. You can raise someones legs if they’re lying down to encourage blood flow to the brain if they’re feeling dizzy.
