Sunburn is a common problem caused by too much exposure to the sun's harmful ultraviolet (UV) rays. Despite warnings about sun damage, many people still get sunburned each year. Sunburn can lead to early wrinkling, age spots, and an increased risk of skin cancer. In this guide, we'll cover the causes, symptoms, treatment, and prevention of sunburn in easy-to-understand terms.
Sunburn is caused by exposure to the sun's UV rays, specifically UVA and UVB rays. These rays penetrate the skin and can cause damage to the DNA in skin cells. The amount of time it takes to get a sunburn depends on your skin type, the sun's intensity, and how long you're exposed to the sun.
The most common symptoms of sunburn include:
Red, painful skin
Swelling
Blisters (in severe cases)
Flu-like symptoms (fever, chills, nausea, headache, weakness)
Peeling and itching skin (a few days after the burn)
If you get a sunburn, there are several things you can do to find relief:
Apply cold compresses or take a cool bath to soothe the skin
Use creams or gels containing menthol, camphor, or aloe vera
Take over-the-counter pain relievers like ibuprofen or naproxen
Stay hydrated by drinking plenty of water and other fluids
Avoid further sun exposure until the burn heals
If you have a severe sunburn with blisters covering a large area of your body, a high fever, or signs of dehydration, contact your doctor.
The best way to deal with sunburn is to prevent it from happening in the first place. Here are some tips for protecting your skin from the sun:
Avoid sun exposure between 10 a.m. and 4 p.m. when the sun's rays are strongest
Wear protective clothing like a broad-brimmed hat, long-sleeved shirt, pants, and UV-blocking sunglasses
Apply broad-spectrum sunscreen with an SPF of at least 30 to all exposed skin, and reapply every 2 hours or after swimming or sweating heavily
Talk to your doctor about any medications you take that may increase your skin's sensitivity to the sun
By following these simple tips, you can enjoy time outdoors while keeping your skin safe from harmful UV rays and reducing your risk of sunburn and skin cancer. Remember, if you notice any unusual changes in your skin, such as a mole that is changing, growing, or bleeding, contact your doctor right away, as this may be a sign of skin cancer.
