Sunburn is the result of excessive exposure of the skin to ultraviolet (UV) rays. These rays damage cells in the epidermis layer of the skin, causing inflammation and erythema (redness). In severe cases of sunburn, some areas of the skin may blister and peel.

What Causes Sunburn?

Sunburn is caused by overexposure of the skin to UV rays. Both UVA and UVB rays can cause sunburn, but UVB rays usually cause more severe burns. Skin type, duration of sun exposure and being outside when the sun is strongest (usually in the afternoon) increase the risk of sunburn.

What are the Complications of Sunburn?

Sunburn can cause complications ranging from mild discomfort to serious health problems:

1. Skin Cancer Excessive sun exposure and sunburns can cause skin cancer. Several types of skin cancer, including melanoma, are at increased risk when exposed to UV rays.
2. Premature Aging: Sunburn can accelerate skin aging, causing wrinkles, age spots and sagging skin.
3. Dehydration Sunburns can cause loss of water and electrolytes from the body, which can lead to dehydration.

How to Prevent Sunburn?

You can follow the steps below to prevent sunburn:

1. Use Sunscreen: Use a broad-spectrum sunscreen with a sun protection factor of at least 30 SPF and reapply every 2 hours and after swimming or sweating.
2. Avoid the Sun Stay in the shade as much as possible when the sun is strongest (usually in the afternoon).
3. Wear Protective Clothing: Protect your skin by wearing long-sleeved shirts, pants and wide-brimmed hats.

How to Treat Sunburn?

Sunburn can usually be treated with the following methods:

1. Cold Compresses and Baths: Cold water baths or cold compresses with wet cloths can relieve pain and inflammation of the skin.
2. Aloe Vera: Aloe Vera can be used to moisturize and soothe the skin.
3. Analgesics Over-the-counter painkillers can help relieve the pain associated with a burn.
4. Hydration Drink plenty of water to compensate for your body's water loss and prevent dehydration.

As a result, it is important to be careful to prevent and treat sunburns. If you have a severe sunburn, you should seek medical attention. Also, always remember to take protective measures when exposing your skin to the sun.
