Sunburn is a form of radiation burn that affects living tissue, primarily the skin, due to overexposure to ultraviolet (UV) radiation, typically from the sun. It manifests as red or reddish skin that is hot to the touch, often accompanied by general fatigue and mild dizziness, and in severe cases, it can be life-threatening. The pathogenesis of sunburn involves individual genetic sensitivity, environmental exposure, and spectral variability, leading to a painful cutaneous inflammatory response. In fruits, sunburn is a physiological disorder caused by excessive solar radiation, resulting in oxidative damage and morphological changes that significantly affect commercial value and yield. The sunburn cell, a type of individual cell death in the epidermis, serves as an index for assessing UV radiation injuries, although the exact mechanisms of its formation remain under investigation.
Types of Sunburn
While most people associate sunburn with red, painful skin, it’s essential to understand that not all sunburns are the same. The severity of sunburn can vary depending on the depth of skin damage and the body’s response to UV exposure. Here are the different types of sunburn categorized by their intensity and symptoms.
- First-degree sunburn
- Second-degree superficial sunburn
- Second-degree deep sunburn
- Third-degree sunburn
Common Causes of Sunburn
Sunburn is a painful reminder of how vulnerable our skin is to ultraviolet (UV) radiation. While spending time outdoors is beneficial for health, overexposure to the sun’s harmful rays can result in skin damage. Various factors contribute to the likelihood of getting sunburned, many of which can be easily overlooked. Here are the most common causes of sunburn, helping you better understand how to protect your skin and avoid unnecessary sun damage.
