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.
High doses of UV radiation kill most of the skin cells in the upper skin layer, and cells that are not killed get damaged. In its mildest form, sunburn consists of a reddening of the skin called erythema. This appears shortly after UV radiation exposure and reaches a maximum intensity between 8 and 24 hours.
