Common First Aid Myths (and What You Should Do Instead) – Part 2

Some first aid myths have been around for generations. Others have become popular through films, television programmes or social media. The problem is that following outdated or incorrect advice could make an injury worse or delay someone from receiving the treatment they really need.

In Part 1 of our First Aid Myths series, we looked at some of the most common misconceptions about treating injuries and medical emergencies.

All good things deserve a sequel so now we're back with even more myths that deserve to be put to rest.

Here are eight more common first aid myths — and what you should do instead.

Help First Aid Training Fainting First Aid

1. If you feel faint, put your head between your knees

Many of us have seen this in films and TV programmes, but it's no longer considered the safest advice.

If you faint while sitting with your head between your knees, you could easily fall forwards, hitting your face or head and causing additional injuries.

What you should do instead

Lie the person flat on their back and, if possible, raise their legs slightly. This helps encourage blood flow back to the brain and may help them recover more quickly.

If appropriate, loosen any tight clothing, allow fresh air to circulate and encourage them to remain lying down until they feel fully recovered. They should avoid standing up too quickly.

2. Someone having a seizure could swallow their tongue

This is one of the most common first aid myths, but thankfully it isn't true. It is physically impossible to swallow your tongue.

Trying to hold someone's tongue or restrain them during a seizure could actually cause injuries to both you and the casualty.

What you should do instead

  • Protect them from injury by moving any nearby hazards.

  • Do not restrain their movements.

  • Time how long the seizure lasts.

  • Stay with them and offer reassurance once the seizure has stopped.

  • When they are breathing normally again, place them in the recovery position.

If the seizure lasts longer than five minutes, repeats without recovery, or it is their first seizure, call 999 immediately.

For more information, read our guide, First Aid for Seizures.

3. You should squeeze a bee sting to remove it

Many people instinctively pinch or squeeze a sting, but this can actually force more venom into the skin.

What you should do instead

Remove the sting as quickly as possible by gently scraping it away using:

  • the edge of a bank card or similar card

  • your fingernail

After removing the sting, wash the area with soap and water and apply a cold compress to help reduce pain and swelling.

4. Never move someone with a suspected spinal injury

Generally, this is good advice. However, there are important exceptions.

If someone is in immediate danger, leaving them where they are could put their life at greater risk than moving them.

For example:

  • there is a fire

  • rising water or another immediate hazard

  • their airway is blocked

  • they are unconscious and vomiting

As Graham often tells learners on our first aid courses:

"There's no advantage in having a perfect spine if you're unable to breathe."

What you should do instead

Only move someone with a suspected spinal injury if it is necessary to protect their life.

If you need advice, call 999 immediately and follow the guidance given by the Emergency Call Handler.

There are techniques for managing the airway of someone with a suspected spinal injury, but these should only be carried out if you have received appropriate training or are being guided by a healthcare professional.

5. A heart attack and a cardiac arrest are the same thing

Although people often use these terms interchangeably, they are very different medical emergencies.

A heart attack happens when the blood supply to the heart muscle is cut off. One of the main causes of this is a clot in one of the coronary arteries. The heart will still be pumping blood around the body during a heart attack, and the person will usually be conscious and breathing.

A heart attack can lead to a cardiac arrest, as the risk of ventricular defibrillation is higher – this is when the heart fibrillates, or quivers, rather than pumps.

A cardiac arrest occurs when the heart’s electrical system stops working, meaning it stops pumping blood effectively. This will lead to the person losing consciousness and their breathing becoming erratic or stopping altogether.

What you should do instead

If you suspect either a heart attack or a cardiac arrest;

  • Call 999 immediately.

  • Ask someone to retrieve the nearest defibrillator (AED).

  • Follow the Emergency Call Handler's advice.

  • If the casualty becomes unconscious and is not breathing normally, start CPR immediately.

6. You must be trained to use a defibrillator

This is another common myth that can stop people from helping.

Modern automated external defibrillators (AEDs) are designed to be used by members of the public. They provide clear spoken and visual instructions throughout the rescue and will only deliver a shock if one is needed.

You do not need formal training to use a defibrillator in an emergency.

What you should do instead

If someone is in cardiac arrest:

  • Call 999 immediately.

  • Send someone to collect the nearest AED.

  • Switch it on and follow the spoken instructions.

  • Continue CPR as directed until the ambulance arrives.

Although anyone can use an AED, attending a Defibrillator Competent User course or a First Aid course allows you to practise using one in a realistic environment. This helps build confidence, reduces panic during a real emergency and gives you the opportunity to ask questions and learn from an experienced first aid instructor.

Our guide Defibrillator Myths Debunked offers more guidance on this subject.
