Fainting, the condition of a brief loss of consciousness, occurs from lack
of oxygen in the brain. Tension on blood vessels can lead to this condition.
For example, a quick turn of the head can reduce blood flow to the brain,
which naturally reduces the oxygen in the brain. Additionally, wearing neckties or shirts with tight collars can put pressure
on the vessels. As a result, the brain, lacking enough oxygen, fails to
work properly.
