The medical term for fainting is syncope. Fainting is a sudden loss of consciousness, usually temporary and typically caused by a lack of oxygen in the brain.

Fainting is most commonly caused by a temporary malfunction in the autonomic nervous system. This type of fainting is sometimes known as neurally mediated syncope.

The autonomic nervous system is made up of the brain, nerves and spinal cord. It regulates automatic bodily functions, such as heart rate and blood pressure.

An external trigger – such as an unpleasant sight, heat or sudden pain – can temporarily cause the autonomic nervous system to stop working properly, resulting in a fall in blood pressure and fainting.

It may also cause your heartbeat to slow down or pause for a few seconds, resulting a temporary interruption to the brain's blood supply. This is called vasovagal syncope.

Syncope is a mechanism used by the brain to help us survive. If brain blood and oxygen levels drop considerably the brain immediately shuts down all other non-vital parts of the body so that resources can focus primarily on vital organs.

What to do if you feel faint:

Don't stay standing up. Find somewhere to either sit or lie down.
If you manage to sit down place your head between your knees.
When you do get up, do so slowly.

People should see their doctor if things go severe.
