Many first aid “tips” have been passed down for generations — but not all of them are correct. In fact, some popular myths can make injuries worse or delay proper treatment. This UK-focused guide busts some of the most common first aid myths and explains the right, NHS-aligned methods you should use instead.
❌ The myth: Applying butter or creams cools the burn and prevents infection.
✅ The fact: Butter and creams trap heat, increase infection risk, and can make injuries worse. Cool burns under cool running water for at least 20 minutes and cover loosely with cling film. Never apply oils, toothpaste, or ice directly.
❌ The myth: Tilting the head back helps stop the bleeding.
✅ The fact: Tilting back can cause blood to run down the throat, leading to choking or stomach irritation. Instead, lean forward slightly and pinch the soft part of the nose for 10–15 minutes.
❌ The myth: Sucking venom out or tying off the limb can prevent poisoning.
✅ The fact: Both methods are dangerous and outdated. In the UK, snakebites are rare, but if they happen, keep the casualty still and call 999 immediately. Do not cut, suck, or apply a tight bandage.
❌ The myth: Cotton wool is soft and ideal for cleaning cuts.
✅ The fact: Cotton fibres can stick to wounds, increasing infection risk. Instead, use clean cloth, sterile gauze or rinse with tap/bottled water. Avoid fibres and tissues.
❌ The myth: Applying ice directly helps cool and heal faster.
✅ The fact: Ice can damage skin tissue. For burns, use cool running water; for sprains or bruises, use a wrapped ice pack or cold compress, not direct contact.
❌ The myth: Pulling out objects like glass or metal helps the wound heal.
✅ The fact: Removing embedded objects can cause severe bleeding or more damage. Leave the object in place, pad around it, and get medical help immediately.
❌ The myth: Only trained professionals can give CPR effectively.
✅ The fact: Hands-only CPR can save lives. When you call 999, the operator will guide you through the steps. Starting CPR is always better than doing nothing.

Many myths come from old first aid practices, TV shows, or advice passed down through families. Techniques evolve over time, and advice that was once considered helpful may now be outdated or even dangerous. It’s important to rely on up-to-date, UK-specific first aid information.
