First Aid for Fainting (Syncope)

Published: October 19, 2026Updated: October 19, 2026

Fainting occurs when a temporary drop in blood flow to the brain causes a sudden, brief loss of consciousness. Most episodes resolve quickly without lasting harm, but prompt first aid helps restore circulation and prevents injury from falling. Knowing how to position the person safely and recognizing when an episode warrants emergency medical evaluation is essential.

Quick Summary

Help the person lie flat on their back, elevate their legs 12 inches to restore blood flow, loosen restrictive clothing, and monitor their breathing until they fully recover.

Step-by-Step Guide

1

Safely Lower the Person to the Ground

If you notice someone starting to faint, assist them safely to the floor to prevent head trauma or fractures from an uncontrolled fall. Position them flat on their back on a safe, level surface. Clear the immediate area of any hard, sharp, or hazardous objects.

Important: Do not attempt to hold the person upright or prop them into a sitting position, as gravity will continue to deprive the brain of adequate blood flow.

2

Elevate Their Legs

Raise the person's feet approximately 12 inches (30 cm) above heart level using a cushion, backpack, or folded clothing. Elevating the legs promotes venous return, helping blood flow back toward the heart and brain to speed up recovery. Only do this if there is no suspected spinal, hip, or lower-limb fracture.

3

Check Breathing and Responsiveness

Observe the chest for normal breathing and check if the person is responsive. Fainting episodes typically last only 20 seconds to a minute; if the person is not breathing or is only gasping, immediately call emergency services (such as 911) and begin CPR. If an automated external defibrillator (AED) is available, send someone to retrieve it.

Important: Never shake the person, slap their face, or use ammonia smelling salts, as these can cause secondary trauma or respiratory irritation.

4

Loosen Restrictive Clothing

Loosen tight neck collars, ties, belts, and snug waistbands to ensure unobstructed breathing and improve circulation. Ensure the surrounding area has adequate air circulation by asking bystanders to step back or opening a nearby window if indoors.

5

Turn into the Recovery Position if Needed

If the person remains unconscious but is breathing normally, or if they begin to vomit or bleed from the mouth, roll them onto their side into the recovery position. This keeps the tongue from obstructing the airway and prevents the aspiration of fluids into the lungs. Keep the head tilted slightly backward to ensure an open airway.

Important: Do not offer food, water, or oral medications until the individual is completely conscious, fully oriented, and sitting upright.

6

Allow a Gradual, Monitored Recovery

Keep the individual lying down for at least 10 to 15 minutes after they regain consciousness. When they feel ready, guide them slowly into a seated position for a few minutes before attempting to stand. If dizziness or lightheadedness recurs at any point, instruct them to lie back down immediately.

Frequently Asked Questions

What should I do if I feel like I am about to faint?
Lie down immediately with your legs elevated to restore cerebral blood flow. If lying down is not possible, sit down and place your head between your knees, or cross your legs tightly and tense your leg, abdomen, and buttock muscles to help raise your blood pressure.
How long does a typical faint last?
A standard vasovagal faint typically lasts between 20 seconds and 1 to 2 minutes. If a person remains unresponsive for longer than 2 minutes, treat it as an emergency and call emergency medical services immediately.
When does fainting require emergency medical care?
Call emergency services if fainting occurs during exercise, is accompanied by chest pain, palpitations, or shortness of breath, involves a head injury, occurs in someone with known heart disease, or is accompanied by signs of a stroke or seizure (such as loss of bowel or bladder control, tongue biting, or prolonged confusion).
Is it safe to give someone sugar or water after they faint?
Only give fluids or a light carbohydrate snack once the person is completely awake, fully alert, and able to swallow normally without assistance. Administering liquids while a person is drowsy or semiconscious creates a dangerous risk of choking and aspiration into the lungs.
