What is Fainting?

Fainting, or syncope, occurs when there is a temporary reduction in blood flow to the brain, causing a sudden, brief loss of consciousness.

Common causes include dehydration, low blood sugar, standing up too quickly, or being in a hot, stuffy environment. Symptoms preceding a fainting episode may include dizziness, light-headedness, sweating, nausea, and a sense of impending loss of consciousness.

When someone faints, they often collapse to the ground, which can be alarming but usually resolves quickly as blood flow returns to the brain. The primary goal of first aid is to prevent injury during the fall and to ensure the person regains consciousness safely.

To assist a person who has fainted, lay them down flat on their back and elevate their legs to improve blood flow to the brain. Ensure they have plenty of fresh air by loosening tight clothing and opening windows if indoors.

If they do not regain consciousness within a minute or two, or if they have a history of heart problems, call for emergency medical assistance.

Once the person is conscious, encourage them to remain lying down until they feel fully recovered to prevent another fainting episode. Offer them water and advise them to avoid sudden movements. Monitoring their condition and reassuring them can help alleviate anxiety and promote a quicker recovery.

First Aid for Fainting

  • Lay the Person Down: Place the casualty on their back with their legs elevated to improve blood flow to the brain.

  • Check for Breathing: Ensure the person is breathing normally. If not, begin CPR.

  • Loosen Tight Clothing: Loosen any tight clothing around the neck and waist.

  • Monitor and Reassure: Keep the person lying down for at least 10 minutes after they regain consciousness and reassure them.

Takeaway to Remember

Fainting, also known as syncope, is a temporary loss of consciousness caused by a decrease in blood flow to the brain. It is often triggered by factors such as dehydration, standing for long periods, or sudden changes in position.
