Facts About Sunburn

What is Sunburn?

Sunburn is a visible reaction of the skin's exposure to ultraviolet (UV) radiation, the invisible rays that are part of sunlight. Ultraviolet rays can also cause invisible damage to the skin. Excessive and/or multiple sunburns cause premature aging of the skin and lead to skin cancer. Skin cancer is the most common type of cancer in the US and exposure to the sun is the leading cause of skin cancer.

During the summer, people spend more time outdoors. People who have fair skin, moles, or freckles, or who have a family history of skin cancer, are more likely to develop skin cancer in later years. UV rays are strongest during summer months when the sun is directly overhead (normally between 10 a.m. and 3 p.m.).

What are the symptoms of sunburn?

The following are the most common symptoms of sunburn. However, each person may experience symptoms differently. Symptoms may include:

• Redness
  
• Swelling of the skin
  
• Pain
  
• Blisters
  
• Fever
  
• Chills
  
• Weakness
  
• Dry, itching, and peeling skin days after the burn
  

The symptoms of sunburn may resemble other skin conditions. Always consult your physician for a diagnosis.

First aid for sunburn:

Here are steps to take if you get a sunburn:

• Take a cool bath or use cool compresses on the sunburned area.
  
• Take acetaminophen or ibuprofen for discomfort. Be sure to follow the directions on the container.
  
• Apply a topical moisturizer, aloe gel, hydrocortisone cream, or a topical pain reliever to sunburned skin. Avoid commercial products that contain Benadryl or benzocaine, because of the possibility of skin irritation or allergy.
  
• If blisters are present, do not break them open, as infection can occur.
  
• Keep out of the sun until the burn is healed.
  

When should I call my physician?

Specific treatment for sunburn will be determined by your physician and may depend on the severity of the sunburn. In general, call your physician if:

• The sunburn is severe or forms blisters.
  
• You have symptoms of heat stress such as fever, chills, nausea, vomiting, or feeling faint.
  

Preventing sunburn:

Protection from the sun should start at birth and continue throughout your life. It is estimated that 60 to 80 percent of total lifetime sun exposure occurs in the first 18 years of life.

The best way to prevent sunburn is to follow the A, B, Cs recommended by The American Academy of Dermatology:

Away: Stay away from the sun in the middle of the day. This is when the sun's rays are the most damaging.

Block: Block the sun's rays using a SPF 15 or higher sunscreen. Apply the lotion 30 minutes before going outside and reapply it often during the day. Sunscreens should not be used on infants under 6 months of age.

Cover-up: Cover up using protective clothing, such as a long sleeve shirt and hat when in the sun. Use clothing with a tight weave to keep out as much sunlight as possible. Keep babies less than 6 months old out of direct sunlight at all times. Hats with brims are important.

What are sunscreens?

Sunscreens protect the skin against sunburns and play an important role in blocking the penetration of ultraviolet (UV) radiation. However, no sunscreen blocks UV radiation 100 percent.

Terms used on sunscreen labels can be confusing. The protection provided by a sunscreen is indicated by the sun protection factor (SPF) listed on the product label. A product with an SPF higher than 15 is called a sunblock.

How to use sunscreens:

A sunscreen protects from sunburn and minimizes suntan by absorbing UV rays. Using sunscreens correctly is important in protecting the skin. Consider the following recommendations:

• Choose a sunscreen and test it on your wrist before using. If you develop skin or eye irritation, choose another brand. Apply the sunscreen very carefully around the eyes
  
• Choose a broad-spectrum sunscreen that filters out both ultraviolet A (UVA) and ultraviolet B (UVB) rays.
  
• Apply sunscreens to all exposed areas of skin, including those easily overlooked areas, such as the rims of the ears, the lips, the back of the neck, and tops of the feet.
  
• Use sunscreens, regardless of skin or complexion type, because all skin types need protection from UV rays. Even dark-skinned people can have painful sunburns.
  
• Apply sunscreens 30 minutes before going out into the sun to give it time to work. Use it liberally and reapply it every two hours after being in the water or after exercising or sweating. Sunscreens are not just for the beach - use them when your outdoors in the yard or participating in sports.
  
• Use a waterproof or water-resistant sunscreen.
  
• Use of a sunscreen with SPF of 20 to 30 offers substantial protection from sunburn and prevents tanning. High SPF sunscreens protect from burning for longer periods of time than do sunscreens with lower a SPF.
  
• Avoid tanning beds and salons. Most tanning beds and salons use ultraviolet-A bulbs. Research has shown that UVA rays may contribute to premature aging of the skin and skin cancer.
