(HealthDay News) -- While there's no such thing as a safe sunburn or tan, some cases can damage the skin permanently.
Sunburn occurs when sunlight or another ultraviolet-light source exceeds the ability of the pigment melanin to protect the skin.
The U.S. National Library of Medicine mentions these warning signs of a serious sunburn:
- Feeling dizzy or faint.
- Rapid breathing or pulse.
- Extreme thirst, a sunken look to the eyes or not producing urine.
- Skin that feels cool or clammy, or appears pale.
- Rash, fever, chills or nausea.
- Pain in the eyes or sensitivity to light.
- Painful blisters.
