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.
Although UVA radiation does not primarily cause sunburn, it does contribute to skin aging and an increased risk of skin cancer. Research has shown that the best sunscreen protection is achieved by application 15 to 30 minutes before exposure, followed by one reapplication 15 to 30 minutes after exposure begins.
