Medical research and clinical experts have highlighted the long-term health risks and immediate complications associated with severe sunburns.

A meta-analysis involving over 321,000 individuals indicates that a history of severe, painful, or blistering sunburns is linked to an increased risk of cutaneous squamous cell carcinoma (cSCC). The study found that individuals with a moderate frequency of such sunburns faced a 51 percent higher relative risk, while those with high frequencies saw a 69 percent increase. Notably, frequent severe sunburns during childhood were associated with approximately triple the risk of developing the disease later in life.

Medical professionals are also distinguishing between mild cases and severe sunburns that require urgent attention. Severe cases are characterized by extensive blistering, intense pain, fever, chills, and general malaise. Complications such as dizziness, nausea, and dehydration may necessitate emergency care. Experts warn that blistering indicates deep skin damage and increases the risk of infection, permanent scarring, and long-term skin cancer due to cumulative DNA damage.
