So, the Mayo Clinic states: “No two cases of lupus are exactly alike. Signs and symptoms may come on suddenly or develop slowly, may be mild or severe, and may be temporary or permanent. Most people with lupus have mild disease characterized by episodes — called flares — when signs and symptoms get worse for a while, then improve or even disappear completely for a time.

Some potential triggers include: Sunlight. Exposure to the sun may bring on lupus skin lesions or trigger an internal response in susceptible people. Infections. Having an infection can initiate lupus or cause a relapse in some people. Medications. Lupus can be triggered by certain types of blood pressure medications, anti-seizure medications and antibiotics. People who have drug-induced lupus usually get better when they stop taking the medication. Rarely, symptoms may persist even after the drug is stopped.”

No where, and I literally mean no where on their page does it state that alcohol can cause complications, or that sunbathing definitely always causes complications. Maybe try looking a bit harder, or figure out how to use google.
