Symptoms of pneumonia not caused by bacteria may come on gradually and are often not as bad or as obvious as symptoms of bacterial pneumonia. Many people don't know that they have nonbacterial pneumonia, because they don't feel sick. But symptoms may include: Fever.
Being exposed to too many UV rays has been linked to these negative health effects: 1  sunburns. 2  premature skin aging. 3  skin cancer. 4  eye damage. 5  weakening of the immune system.
Sunburn can occur in less than 15 minutes, and in seconds when exposed to non-shielded welding arcs or other sources of intense ultraviolet light. Nevertheless, the inflicted harm is often not immediately obvious. After the exposure, skin may turn red in as little as 30 minutes but most often takes 2 to 6 hours. Pain is usually most extreme 6 to 48 hours after exposure. The burn continues to develop for 1 to 3 days, occasionally followed by peeling skin in 3 to 8 days. Some peeling and itching may continue for several weeks.
