To continue with this month's newsletter subject on Sunscreen and Skin Care, here are some warning signs to suggest that you have had too much sun.   

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.
