Cool running water is the answer. For a minor burn, the first and most important step is to cool it under cool running water for 20 minutes. This simple action can limit the depth of the injury and ease pain. After cooling, you can cover the burn loosely with a clean dressing or cling film to protect it. Do not apply ice, butter, toothpaste, or ointments to a fresh burn.
What Is The Correct First Aid For A Burn?
Immediate and correct first aid can reduce the severity of a burn and speed up healing. The goal is to stop the burning process and cool the tissue.
Follow these steps for a minor burn:
- Stop the burning. Remove the person from the heat source or electrical source. If clothing is on fire, have them stop, drop, and roll. Remove any clothing or jewelry that is not stuck to the burn, as these can hold in heat and cause swelling.
- Cool the burn. Hold the burn under cool, gently running water for 20 minutes. This is the most critical step. If running water is not available, immerse the area in a container of cool water. Do not use ice, iced water, or very cold water. This can cause further damage to the skin and lower body temperature.
- Keep the person warm. Cooling a large burn can cause a person’s body temperature to drop. While cooling the burn, try to keep the rest of the person’s body warm with a blanket.
- Cover the burn. After cooling, cover the burn loosely. A clean, non-fluffy dressing or a piece of cling film is good. Cling film should be laid over the burn, not wrapped tightly around a limb. This protects the area from infection and reduces pain from air exposure.
- Manage pain. Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage discomfort. Always follow the instructions on the label.
Do not break any blisters that form. Blisters are a natural part of healing and breaking them increases the risk of infection.
What Should You Never Put On A Burn?
Many traditional home remedies for burns are not helpful and can cause more harm. The evidence is clear that these substances should be avoided.
Applying the wrong thing to a burn can trap heat, introduce bacteria, and complicate the healing process. It can also make it difficult for a doctor to assess the burn’s severity.
Avoid putting these on a burn:
- Ice: Applying ice directly to a burn can cause frostbite and further damage the tissue. It can also restrict blood flow to the area, which is needed for healing.
- Butter, oil, or grease: These substances hold heat in the wound, which can make the burn deeper. They are also not sterile and can introduce bacteria, leading to infection.
- Toothpaste: Toothpaste is not sterile and contains ingredients that can irritate the wound. It offers no healing benefit and can increase the risk of infection.
- Ointments and creams: Do not apply ointments, lotions, or creams to a fresh burn before it has been cooled and assessed. They can trap heat and interfere with healing. Some topical antibiotics can be used later, but only on the advice of a healthcare professional.
- Cotton wool or fluffy dressings: The fibers from these materials can stick to the burn and are difficult to remove, which can cause further damage when changing the dressing.
The best approach is to stick to the basics: cool water and a clean, non-stick covering.
When Does A Burn Need Medical Attention?
Knowing when a burn is more serious than it looks is important. Some burns require professional medical care, even if they seem small at first.
You should seek medical help for a burn if:
- The burn is larger than the size of the person’s palm.
- The burn is on the face, hands, feet, genitals, or across a major joint.
- The burn looks deep. This could mean it is white, brown, or charred, or if the skin appears leathery. A deep burn may also be numb because the nerves have been damaged.
- The burn was caused by chemicals or electricity.
- The person has inhaled smoke or hot fumes, which can cause damage to the airways.
- The person is an infant, an older adult, or has a condition like diabetes or a weakened immune system.
- There are signs of infection, such as increasing pain, redness, swelling, pus, or a fever.
For these types of burns, do not apply any creams or ointments. Cover the burn loosely with a clean cloth or cling film and go to an emergency department or urgent care center.
How Do You Treat A Burn After The First 24 Hours?
After the initial cooling and assessment, the focus shifts to protecting the burn and supporting the body’s natural healing process. A minor burn will typically heal on its own within a week or two, but proper care can help prevent complications.
Keep the burn clean and covered. You can gently wash the area with mild soap and water once a day. Avoid scrubbing. After washing, pat the area dry with a clean, soft cloth and apply a new, clean dressing. A non-stick sterile gauze pad works well. Change the dressing daily or whenever it becomes wet or dirty.
Pain and swelling are common in the first few days. Over-the-counter pain medication can help. You can also elevate the burned area if possible to reduce swelling.
Once the skin has started to heal and is no longer an open wound, you can apply a fragrance-free moisturizer to keep the new skin hydrated. Protect the healing skin from the sun, as it can be more sensitive to sunburn and may develop dark spots. It is important to monitor for any signs of infection and seek medical advice if they appear.
What Are The Different Types Of Burns?
Burns are classified by how deeply they damage the skin. Understanding the type of burn helps determine the right treatment. The classification is based on the layers of skin affected.
The skin has three main layers: the epidermis (outer layer), the dermis (middle layer), and the subcutaneous tissue (deepest layer of fat and tissue).
Here is a breakdown of the common burn classifications:
| Burn Type | Layers Affected | Appearance | Common Causes |
|---|---|---|---|
| First-Degree (Superficial) | Epidermis only | Red, dry, painful, no blisters | Sunburn, brief contact with hot objects |
| Second-Degree (Partial Thickness) | Epidermis and part of the dermis | Red, blistered, swollen, very painful | Scalds from hot water, flames, contact with hot objects |
| Third-Degree (Full Thickness) | All layers of the skin | White, brown, or charred; leathery; may be numb | Flames, electricity, chemicals, prolonged contact with hot objects |
A first-degree burn is what most people think of as a minor burn. A second-degree burn is more serious and involves blistering. A third-degree burn is a major injury that always requires emergency medical care. The distinction matters because the treatment and urgency of care are different for each.
Does The Type Of Burn Change What You Should Do?
Yes, the type of burn directly affects the first aid steps and the urgency of seeking medical care. The general principle of cooling with water applies to most burns, but with important exceptions.
For a first-degree burn, such as a mild sunburn, cooling the skin with cool water or a cool compress can provide relief. You can also use soothing lotions like aloe vera gel. These burns usually heal on their own in a few days.
For a second-degree burn, the priority is still cooling with water for 20 minutes. Do not break any blisters. After cooling, cover the burn loosely with a clean, non-stick dressing. Because these burns are deeper, they have a higher risk of infection and may need to be seen by a doctor, especially if they are large or on a sensitive area.
For a third-degree burn, do not immerse the burn in cool water. This can lead to hypothermia and other complications. The priority is to call emergency services immediately. While waiting for help, cover the burn with a clean, dry cloth or sterile dressing. Do not apply any water, creams, or ointments. These burns are medical emergencies.
Chemical burns also require a different approach. If a chemical gets on the skin, brush off any dry chemical first, then flush the area with cool running water for at least 20 minutes. Remove any contaminated clothing while flushing. Seek immediate medical attention.
Frequently Asked Questions
Should I use butter or toothpaste on a burn?
No, you should never use butter, toothpaste, or oil on a burn. These home remedies trap heat, can introduce bacteria, and increase the risk of infection without helping the burn heal.
How long should I cool a burn with water?
You should cool a minor burn under cool running water for 20 minutes. This is the most effective way to limit tissue damage and reduce pain.
When should I go to the hospital for a burn?
Go to the hospital if a burn is larger than your palm, is on your face, hands, feet, or genitals, or looks white, charred, or leathery. You should also seek care for burns caused by chemicals or electricity, or if there are signs of infection.
Can I put ice on a burn to cool it down?
No, you should not put ice on a burn. Ice can cause frostbite and further damage the skin tissue, and it can restrict blood flow which is needed for healing.
