Key Points

  • Sunburn is a skin condition caused by excessive UV rays exposure, resulting in damaged DNA in skin cells and symptoms like red, painful skin, swelling, and blisters.
  • Factors like prolonged sun exposure, high altitudes, reflective surfaces, light skin, and lack of protective measures can increase the risk of sunburn.
  • Sunburn is not contagious but can be prevented by limiting sun exposure, using sunscreen, wearing protective clothing, and avoiding tanning beds.
  • If sunburn occurs, immediate treatment such as cool baths, moisturizers, pain relievers, hydration, and avoiding further sun exposure can help manage symptoms and limit skin damage.
  • Sunburn can lead to serious long-term complications like increased skin cancer risk, premature skin aging, dehydration, and secondary skin infections, emphasizing the importance of prevention and effective management.

What is Sunburn?

Sunburn is the skin's response to excessive UV radiation exposure. According to the Mayo Clinic, UV radiation causes damage to the DNA in skin cells, leading to skin inflammation and other symptoms associated with sunburn.

Symptoms of Sunburn

The symptoms of sunburn can vary depending on the severity and your skin type. They include:

  • Red, painful skin that feels warm or hot to the touch.
  • Swelling and blisters in more severe cases.
  • Headache, fever, nausea, and fatigue if the sunburn is severe (a condition known as sun poisoning).
  • Peeling skin in the days following the burn.

The Cleveland Clinic emphasizes that symptoms typically appear within a few hours after sun exposure and can worsen over the next 24-36 hours.

Causes of Sunburn

Sunburn is caused by overexposure to UV rays. Factors that can increase your risk include:

  • Prolonged sun exposure, especially without protective clothing or sunscreen.
  • Being at higher altitudes, where UV exposure is greater.
  • Being near reflective surfaces like water, snow, or sand, which can reflect and intensify UV rays.
  • Having light skin, as it's more susceptible to UV damage.

Transmission and Prevention

Sunburn is not contagious but is highly preventable. The Skin Cancer Foundation and the CDC recommend these prevention strategies:

  • Limit sun exposure, especially between 10 a.m. and 4 p.m. when the sun's rays are strongest.
  • Use a broad-spectrum sunscreen with an SPF of at least 30. Reapply every two hours, or more often if swimming or sweating.
  • Wear protective clothing, hats, and sunglasses.
  • Seek shade whenever possible, especially during midday hours.
  • Avoid tanning beds and sunlamps, which also emit harmful UV rays.

By taking these preventive steps, you can significantly reduce your risk of sunburn and the long-term damage it can cause to your skin, including the risk of skin cancer as noted by the Skin Cancer Foundation and MedlinePlus. If you do get sunburned, it’s important to start treatment immediately to manage symptoms and limit damage to your skin.

Diagnosis or Testing

Sunburn is generally diagnosed based on its visible symptoms and a history of recent sun exposure. As the American Academy of Dermatology Association points out, in most cases, no special testing is required. However, in severe cases with extensive blistering or signs of systemic illness, medical attention may be necessary.


While sunburn itself is temporary, it can lead to more serious long-term complications, including:

  • Increased risk of skin cancer, as noted by the Skin Cancer Foundation.
  • Premature aging of the skin.
  • Severe cases can lead to sun poisoning, dehydration, and secondary skin infections.


Treatment for sunburn focuses on relieving symptoms and promoting healing:

  • Cool baths or compresses can soothe sunburned skin.
  • Moisturizers containing aloe vera or soy can help.
  • Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can reduce pain and swelling.
  • Stay hydrated by drinking extra water.
  • Avoid further sun exposure while the skin heals.

The Mayo Clinic and Cleveland Clinic recommend these treatments to alleviate discomfort and speed up recovery.

At-Home Remedies

In addition to medical treatments, some at-home remedies can be effective:

  • Apply aloe vera gel to soothe and cool the skin.
  • Use cool (not cold) milk compresses.
  • Wear loose, soft clothing over sunburned areas.

When to See a Doctor

Seek medical care if:

  • The sunburn covers a large portion of your body or is accompanied by blisters.
  • You experience severe pain, headache, confusion, nausea, or chills.
  • You show signs of dehydration or sun poisoning.

Role of Urgent Care Centers

For immediate relief or concerns about sunburn, visiting an urgent care center can be helpful. These centers offer quick assessments and can provide treatment advice, especially when primary care appointments are not available.

Final Thought

Sunburn, while often viewed as a temporary discomfort, can have serious long-term effects on skin health. Effective management, including prompt treatment and preventive measures, is crucial.
