Baby Banz - Ultimate in children's sun protection

What is sunburn?

Sunburn is the visual coloration of the skin resulting from radiation damage. While UVA rays contribute to sunburns, most sunburn damage is caused by overexposure to UVB rays (see “difference between UVA and UVB rays” below) from the sun or tanning beds. As ultraviolet light hits the outer layer of the skin (the epidermis), it begins to damage and kill living skin cells. In the body’s effort to protect itself, the immune system kicks in increasing blood flow to the damaged area which causes the area to become warm and red. Eventually, the damaged cells release chemicals that trigger pain receptors and sunburned skin becomes sensitive and painful.

Individuals are born with varying degrees of natural protection against sunburn. The amount of melanin (a pigment) in the skin largely determines the color of the skin. Pigment absorbs UV radiation from the sun thus protecting skin cells from damage. Generally, the more melanin a person has in their skin to begin with, the more they are protected. When skin is exposed to ultraviolet light, melanocytes, which produce melanin, become more active causing the skin to tan. Fair-skinned, light-haired people have very little natural defense against sunburn and are highly susceptible to sunburn. While those with darker skin do have a bit of an advantage, anyone can get sunburned and everyone is at risk for sun damage.

Does age factor into sunburn damage?

A large amount of exposure to the sun does happen during childhood. Once damage is done to skin cells, the damage cannot be reversed. Make sure your children are protected. However, it is never too late to take sun protective measures and people of all ages need to protect from sun overexposure every day.

Are the sun’s rays more intense at higher altitudes?

UV radiation increases 4% for every 1000 foot increase in elevation (i.e. UV radiation is 20% more intense at 5000 feet than at sea level).

Can I get a sunburn in the winter?

Absolutely! The sun can actually be more dangerous in winter than summer as many people let their guards down. Many forget that although the sun’s rays aren’t as direct in winter as in summer, exposed skin can still be damaged. Higher altitudes mean more intense UV radiation exposure and snow is highly efficient at reflecting sunlight.

Can I get sunburned from the sun reflecting on a surface?

UV rays that are reflected can be just as damaging as direct exposure

• Sand/concrete reflects 25% UV radiation
• Snow reflects 85% UV radiation
• Water reflects 100% UV radiation

What is the difference between UVA and UVB rays?

• UVA rays have long wavelengths and penetrate deeply while UVB rays have short wavelengths and are the primary cause of sunburns
• UVA rays damage skin’s connective tissues leading to premature aging and contributing to skin cancer development while UVB rays are the primary contributor to skin cancer development
• UVA rays pass through window glass while UVB rays are blocked by window glass

Make sure your sunscreen is a “broad spectrum” sunscreen which protects against both UVA and UVB rays.

Does medication affect my time in the sun?

Yes. Certain medications, such as antibiotics or drugs containing hormones, can make the skin much more sensitive to sun exposure and damage. Always consult a physician to understand the side effects that a medication can have.

Doesn’t sun exposure give me necessary vitamin D?

Sun exposure, together with a healthy, balanced diet is important in the body’s production of vitamin D. Just be sure to diligently protect yourself with sunscreen and sun protective clothing when you are active in the sun.
