Sunburn vs sun poisoning is an important distinction to understand when it comes to the effects of excessive sun exposure. While sunburn is a common reaction that leads to redness, peeling, irritation, and discomfort, prolonged exposure to intense UV rays can trigger a more serious condition known as sun poisoning.
Unlike mild sunburn, sun poisoning can include symptoms such as blistering, severe inflammation, dehydration, fever, and dizziness. Recognizing the signs of both conditions is essential for timely treatment and prevention. Knowing the differences between sunburn vs sun poisoning can help you protect your skin and respond appropriately to each condition.

What Is Sunburn?
Sunburn occurs when the skin’s outer layer (epidermis) is damaged due to excessive exposure to ultraviolet (UV) radiation from the sun. In more severe cases, UV rays can penetrate deeper into the dermis, leading to increased inflammation and discomfort if left untreated.
Prolonged sun exposure without adequate protection increases the risk of sunburn, causing symptoms such as redness, swelling, peeling, rashes, and a warm sensation on the affected areas. Severe cases of sunburn can progress to sun poisoning, which may result in blistering, dizziness, dehydration, and flu-like symptoms.
A survey conducted among over 1,000 U.S. adults found that while 62% of participants considered themselves mindful of sun protection, 63% still got a tan. Additionally, 67% mistakenly believed that SPF 30 sunscreen provides twice as much protection as SPF 15, and 65% admitted to forgetting to reapply sunscreen. These misconceptions contribute to the high occurrence of sunburn, with one-third of respondents reporting they had experienced it.
Proper sun protection, including the use of broad-spectrum sunscreen, wearing protective clothing, and limiting sun exposure during peak hours, can help prevent sunburn and its potential complications.
What Is Sun Poisoning?
Sun poisoning is a severe form of sunburn that occurs after prolonged exposure to ultraviolet (UV) radiation without adequate sun protection. Unlike mild sunburn, which typically heals within a week, sun poisoning can cause more intense symptoms and may take several weeks to fully recover from, depending on the extent of skin damage.
This condition is sometimes referred to as an allergic reaction to excessive UV exposure, as it triggers an inflammatory response in the body. Symptoms can go beyond typical sunburn, including blistering, swelling, fever, dehydration, and dizziness. Proper treatment and immediate care are essential to prevent complications and aid recovery.
Sunburn vs. Sun Poisoning: Key Differences
Daniel Boyer, M.D., explains that sunburn occurs when the skin becomes irritated or red after short-term sun exposure, while sun poisoning is a more severe allergic reaction due to prolonged UV exposure. The severity of sunburn may vary based on location, duration of exposure, and skin type. However, sun poisoning can cause intense symptoms regardless of these factors when the skin is exposed to the sun for extended periods.
Symptoms
Sunburn
- Redness
- Swelling
- Itching
- Tenderness
- Skin that feels warm to the touch
Sun Poisoning
- Itchy red rash
- Blistering
- Skin peeling
- Dehydration
- Headache or dizziness
- Fever or chills
- Nausea
- Joint pain
- Muscle aches
Risk Factors
Certain individuals are more prone to sunburn and sun poisoning. Knowing these risk factors can help in taking preventive measures.
You are more likely to get sunburned or experience sun poisoning if you:
- Have light or fair skin
- Live near the equator or at high altitudes
- Work outdoors
- Swim or have wet skin, as wet skin burns faster than dry skin
- Drink alcohol while exposed to the sun
- Do not use sun protection
- Have medical conditions like lupus, eczema, or rosacea
- Take antibiotics, birth control pills, or acne medications
- Have a history of skin cancer
Individuals with albinism, a genetic condition affecting melanin production, and those taking medications that increase sun sensitivity are also at greater risk.
Dr. Boyer emphasizes that while sunburn results from short-term sun exposure on sensitive skin, sun poisoning occurs when the skin is subjected to prolonged UV radiation, regardless of skin type.
There are several home treatments available to help soothe the symptoms of both sunburn and sun poisoning.
Natural Remedies to Try
1. Apply Aloe Vera Gel
Aloe vera is widely recognized for its burn-healing properties, making it an effective remedy for sunburn blisters. Its anti-inflammatory characteristics help reduce pain and inflammation caused by burns and wounds. Aloe vera gel also hydrates the skin and promotes collagen production, which can aid in the healing process.
To use aloe vera, apply a generous amount of fresh gel directly to the affected area. Avoid popping blisters, as this can increase the risk of infection.
2. Try Cold Compress and Cold Showers
While cool showers and compresses won’t stop peeling, they can provide temporary relief by soothing inflamed and overheated skin.
If a cold pack is unavailable, you can create one at home by placing ice cubes in a thick plastic bag. However, never apply ice directly to sunburned skin, as extreme cold can cause further irritation and delay healing.
3. Stay Hydrated
Hydration plays a crucial role in helping the skin recover from sunburn. Drinking plenty of water aids in skin repair, while coconut water is particularly beneficial for replenishing lost electrolytes due to sun exposure.
4. Take an Oatmeal Bath
Colloidal oatmeal has anti-inflammatory properties that help relieve burns, swelling, and itching while improving moisture retention. Unlike regular breakfast oatmeal, colloidal oatmeal is made by grinding whole oats into a fine powder.
To prepare an oatmeal bath:
- Grind uncooked whole oats in a food processor until you get a fine powder.
- Mix one cup of oatmeal powder into a tub of lukewarm water.
- Soak in the bath for 10-15 minutes to soothe the skin.
5. Treat the Blisters
If sunburn causes rashes or blisters that rupture, gently cleanse the affected area with soap and water. Apply an antiseptic ointment and cover it with a non-stick gauze pad or bandage to prevent infection.
Additional home remedies that may help include:
- Adding baking soda to a cool bath
- Applying honey to the affected area for its antibacterial and soothing properties
6. Take Anti-Inflammatory Medicine
Aspirin and ibuprofen are non-steroidal anti-inflammatory drugs (NSAIDs) that can help reduce pain and inflammation caused by sunburn. These medications can be taken orally or crushed into a paste with water for direct application to the affected skin. Anti-inflammatory creams may also be used, but avoid petroleum-based lotions or heavy moisturizers, as they can trap heat and worsen irritation.
How to Prevent Sunburn and Sun Poisoning
- Stay out of the sun as much as possible, especially during peak hours (10 a.m. to 4 p.m.).
- Wear protective clothing such as wide-brimmed hats, sunglasses, and long-sleeved garments when outdoors.
- Apply a broad-spectrum sunscreen with an SPF of 35 or higher 15 to 30 minutes before sun exposure, and reapply every two hours or after swimming or sweating.
- Be mindful of medications that increase sun sensitivity, such as antibiotics, acne treatments, and certain birth control pills.
- Drink plenty of water to stay hydrated and prevent dehydration caused by excessive sun exposure.
- Keep infants out of direct sunlight and ensure their skin is protected.
- Avoid tanning beds, as they expose the skin to harmful UV radiation and increase the risk of sunburn and long-term skin damage.
If sunburn symptoms are severe or do not improve over time, seek medical advice. Since sun poisoning can lead to serious complications, it is crucial to visit a doctor and start treatment immediately if symptoms worsen.
