Sunscreen for babies? Maybe not

You’re at the beach, slathered in sunscreen. Your 5-month-old baby is there, too.

Should you put sunscreen on her? Not usually, according to Hari Cheryl Sachs, MD, a pediatrician at the Food and Drug Administration (FDA).

“The best approach is to keep infants under 6 months out of the sun,” Sachs says, “and to avoid exposure to the sun in the hours between 10 am and 2 pm, when ultraviolet (UV) rays are most intense.”

Sunscreens are recommended for children and adults. What makes babies so different?

The need for sun safety has become clearer over the past 30 years. Sun damage to the body is caused by invisible ultraviolet (UV) radiation. Even on an overcast day, up to 80 percent of the sun’s UV rays can get through the clouds, so stay in the shade as much as possible throughout the day.

Sunscreen for babies? Maybe not“Babies’ skin is less mature compared to adults, and infants have a higher surface-area to body-weight ratio compared to older children and adults,” explains Sachs. “Both these factors mean that an infant’s exposure to the chemicals in sunscreens may be much greater, increasing the risk of side effects from the sunscreen.”

“The best protection is to keep your baby in the shade, if possible,” Sachs says. “If there’s no natural shade, create your own with an umbrella or the canopy of the stroller.”

First or last: Birth order hardly changes personality or IQ

“If there’s no way to keep an infant out of the sun, you should check with your pediatrician about what to do for your baby.”

If your pediatrician agrees, you can apply a small amount of sunscreen to small areas, such as the cheeks, tip of nose, tops of ears and back of the hands. (Sachs suggests testing your baby’s sensitivity to sunscreen by first trying a small amount on the inner wrist.)

Choose sunscreen with a “sun protection factor” (SPF) of 15 or more. SPF represents the degree to which a sunscreen can protect the skin from sunburn. Also look for “broad spectrum” protection, which protects against all types of skin damage caused by sunlight.

Cover your baby up

The American Academy of Pediatrics (AAP) suggests dressing infants in lightweight long pants, long-sleeved shirts, and brimmed hats that shade the neck to prevent sunburn. Tight weaves are better than loose. You can also get clothing that blocks out UV radiation, front brands such as NoZone and Coolibar.

Keep in mind that while baseball caps are cute, they don’t shade the neck and ears — all sensitive areas for a baby. Instead, consider one of the many sun protection hats designed for babies.

Summer’s heat presents other challenges for babies.

“Younger infants also don’t sweat like we do,” Sachs says. “Sweat naturally cools the rest of us down when we’re hot, but babies haven’t yet fully developed that built-in heating-and-cooling system. So you want to make sure your baby doesn’t get overheated.”

How the APGAR score works

“In the heat, babies are also at greater risk of becoming dehydrated. To make sure they’re adequately hydrated, offer them their usual feeding of breastmilk or formula,” says Sachs. “The water content in both will help keep them well hydrated.”

Sun safety tips for infants

Here are a few more things to keep in mind this summer when outside with infants:

  • Keep your baby in the shade as much as possible.
  • Consult your pediatrician before using any sunscreen on your baby. If you do use a small amount of sunscreen on your baby, don’t assume the child is well protected.
  • Make sure your child wears clothing that covers and protects sensitive skin. Use common sense; if you hold the fabric against your hand and it’s so sheer that you can see through it, it probably doesn’t offer enough protection.
  • Make sure your baby wears a hat that provides sufficient shade at all times.
  • Watch your baby carefully to make sure he or she doesn’t show warning signs of sunburn or dehydration. These include fussiness, redness and excessive crying.
  • Hydrate! Give your baby formula or breast milk if you’re out in the sun for more than a few minutes. Don’t forget to use a cooler to store the liquids.
  • Take note of how much your baby is urinating. If it’s less than usual, it may be a sign of dehydration, and that more fluids are needed until the flow is back to normal.
  • Avoid combination sunscreens containing insect repellents like DEET. Young children may lick their hands or put them in their mouths. According to the AAP, DEET should not be used on infants less than 2 months old.
  • If you do notice your baby is becoming sunburned, get out of the sun right away and apply cold compresses to the affected areas.
