Sunlight Exposure For Newborns: How Much Is Too Much?

how long newborn sunlight

Newborns have very delicate skin and are vulnerable to sun damage. Their skin is not mature enough to form a barrier against UV rays, and their eyes are also not fully developed, lacking the pigment that filters out UV rays. This means that UV rays can more easily reach the retina and cause damage. The Skin Cancer Foundation recommends that infants under 6 months of age be kept out of direct sunlight, and that parents and babies seek shade under a tree, umbrella, or stroller canopy. During outdoor activities, it is best to plan ahead and be mindful of the time of day, opting for early morning or late afternoon when UV levels are lower. When spending time outdoors during the day, it is important to monitor UV levels and keep trips relatively brief during moderate to high UV times.

Keep newborns out of direct sunlight for the first six months

The first six months of a baby's life are critical for their skin development, and it is important to shield them from direct sunlight during this period. Here are some detailed guidelines to ensure your newborn stays safe and healthy while still being able to enjoy the outdoors:

Plan Outdoor Activities Carefully

While it is not necessary to be confined indoors, it is advisable to plan outdoor activities during the early morning or late afternoon when UV levels are naturally lower. If you need to go out during the day, keep a close eye on the UV index. Download a reliable app that provides current and maximum UV levels in your area, such as the SunSmart app.

Keep Trips Brief During Moderate to High UV Times

During periods of moderate to high UV radiation (UV index of 3 or above), it is recommended to limit your outdoor exposure. The higher the UV level or outdoor temperature, the shorter your time outside should be. Even during low UV times (UV index below 3), it is crucial to protect your baby from direct sunlight by seeking shade or using appropriate sun protection.

Provide Adequate Sun Protection

Use methods that create a physical barrier between your baby and the sun. This includes using pram shades, large-brimmed sun hats that shield the eyes, ears, and neck, and lightweight clothing that covers the arms and legs. You can also try sunglasses for your baby if they are comfortable wearing them. These measures are essential to blocking harmful UV rays and preventing potential damage to your baby's skin and eyes.

Be Cautious with Sunscreen Use

While it is generally recommended to avoid sunscreen for babies under six months, if you are concerned about UV levels, you can opt for a sunscreen specifically designed for infants. Apply it to small unclothed areas, such as the tops of their feet. However, always prioritize creating a physical barrier between your baby and the sun as the primary defence strategy.

Take Extra Precautions in the Car

When travelling in the car, use a shade or barrier to block UV rays from entering through the backseat window. Do not cover the baby's capsule seat, as this can lead to heat stress. Additionally, never leave your baby unattended in a car, as it can quickly overheat.

Keep Your Baby Well-Hydrated

Offer frequent breastfeeds or bottle feeds to ensure your baby stays hydrated in hot weather. Check their temperature regularly by placing your hand against their torso.

Be Mindful of Their Comfort

Keep your baby's pram cool and comfortable. Do not let it heat up before placing your baby inside, and consider removing the back panel or using a pram fan or cooling liner. Check on your baby frequently to ensure they are comfortable and not overheating.

By following these guidelines, you can safely enjoy the outdoors with your newborn while protecting them from the potential harms of direct sunlight during their first six months of life.

Plan outdoor activities for early morning or late afternoon

Planning Outdoor Activities for Newborns

The first six months of a newborn's life are critical for their health and safety, especially when it comes to sun exposure. Here are some detailed guidelines to plan outdoor activities for early morning or late afternoon, ensuring the well-being of your precious newborn:

Timing is Key

When planning outdoor activities with your newborn, timing is of the essence. Aim for early morning walks before 10 am or opt for late afternoon strolls after 4 pm. These times of the day generally have lower UV levels, reducing the risk of sun damage to your baby's delicate skin.

Create a Physical Barrier

It is crucial to protect your newborn from direct sunlight. Use a pram or stroller with a sunshade or canopy to provide shade for your baby. Additionally, dress your little one in lightweight clothing that covers their arms and legs. Choose light colours as they reflect more sunlight. Long sleeves and pants will shield their sensitive skin from harmful UV rays. Don't forget to put a cute baby hat with a brim on them to protect their face, ears and neck.

Stay Vigilant About Sun Protection

Even during early morning or late afternoon outings, it's essential to remain vigilant about sun protection. Keep an eye on the UV levels using a SunSmart app on your phone. This will help you monitor the current and maximum UV levels in your area. If the UV level is 3 or above, keep your outdoor time relatively brief, and always ensure your baby is protected from direct sunlight.

Hydration is a Priority

Newborns can become dehydrated quickly, so it's crucial to prioritise their hydration during outdoor activities. If you are breastfeeding, your baby may want to feed more often in hot weather. If you are bottle-feeding, you can offer them cooled boiled water in addition to their usual milk feeds. Always have extra water on hand and frequently offer it to your baby to prevent dehydration.

Be Mindful of the Surroundings

When outdoors with your newborn, be mindful of the surroundings. Avoid places with limited shade, such as open fields or beaches, especially during the hottest parts of the day. Opt for parks with plenty of trees or shaded areas, and remember to keep your baby away from direct sunlight even when under a tree or umbrella.

Avoid Overheating

While protecting your newborn from the sun is crucial, it's also important to prevent them from overheating. Do not cover the pram or stroller with a blanket, as it can lead to excessive heat. Dress your baby in layers, and if you notice they are getting warm, remove a layer to help regulate their body temperature.

Use sun protection methods that create a physical barrier

Protecting Newborns from the Sun

Newborns have very delicate skin that is not yet mature enough to form a good barrier against UV rays. Their eyes are also not fully developed and lack the pigment that filters out UV rays. This makes them very vulnerable to UV damage, perhaps more so than they will ever be again in their lifetime.

Using Sun Protection Methods that Create a Physical Barrier

  • Plan outdoor activities during the early morning or late afternoon: UV levels are naturally lower during these times.
  • Check UV levels: Download the SunSmart app on your phone to monitor current and maximum UV levels in your area. Keep outdoor trips brief during moderate to high UV times (UV level 3 or above). The higher the UV level or outdoor temperature, the shorter your outdoor time should be.
  • Stay in the shade: Keep your baby protected from direct sunlight by sticking to shady areas. Use a pram with a sunshade or a stroller with a sun-protective cover.
  • Use a hat: Always protect your baby's head, face, eyes, ears, and neck with a wide-brimmed sun hat that shields these areas. A baby who wears a hat from their early days will get used to having it on.
  • Use appropriate clothing: Dress your baby in lightweight, sun-protective clothing that covers their arms and legs. Clothes made with sun-protective fabrics typically have a tighter weave and are darker in color. Look for clothing with a Ultraviolet Protection Factor (UPF) label, which indicates the garment's ability to protect against UV rays.
  • Use sunglasses: Overexposure to UV light contributes to the development of cataracts, retinal damage, and other eye problems. Use sunglasses with UVA/UVB protection to protect your baby's eyes.
  • Use a car shade or UV window film: Use a shade or barrier to block UV rays coming through the backseat window where your baby is sitting. Alternatively, invest in UV window film, which can screen almost 100% of ultraviolet radiation without reducing visibility.
  • Use a pram cover: Choose a pram cover that provides adequate ventilation and keeps your baby cool and comfortable.

Dress newborns in lightweight, sun-protective clothing

The skin of a newborn baby is extremely delicate and vulnerable to sun damage. In fact, babies under six months old should be kept out of direct sunlight altogether. So, when taking your newborn outdoors, it's important to dress them in lightweight, sun-protective clothing that covers their arms and legs.

What to look for in sun-protective clothing

A fabric's Ultraviolet Protection Factor (UPF) indicates how much of the sun's UV radiation can penetrate it. The higher the UPF, the higher the protection. For context, the average white cotton t-shirt has a UPF of 5, allowing one-fifth of the sun's UV rays to pass through. By contrast, sun-protective clothing typically has a UPF of 30 or higher, blocking 97% or more of UV rays.

When choosing sun-protective clothing for your newborn, look for garments with a UPF of at least 20. The fabric should be lightweight, breathable, and ideally darker in colour, as darker hues absorb more UV radiation than lighter ones.

Recommended items of sun-protective clothing

  • A brimmed hat with a wide brim of around 3 inches to protect your baby's head, face, ears and neck.
  • Long-sleeved tops and long pants to cover their arms and legs.
  • Socks to protect their feet.
  • Sunglasses with UVA/UVB protection to shield their eyes.

Use sunscreen on newborns over six months old

The American Academy of Pediatrics (AAP) recommends keeping newborns and babies younger than six months out of direct sunlight. Their skin is not mature enough to form a good barrier against UV rays, and their eyes are also not fully mature as they lack the pigment that filters out UV. This means that UV can reach the retina more easily than in an adult, and can cause damage.

The best sun protection for these infants is to stay in the shade. Look for natural shade, such as under a tree, or create your own shade using a beach umbrella, a pop-up tent, or a stroller canopy. It is also recommended to dress infants in lightweight clothing, such as long pants and long-sleeve shirts. Babies should wear a hat with a brim that shades the neck to prevent sunburn. Not baseball caps, which don’t shade the neck or ears, both of which are sensitive areas for a baby.

However, once your baby reaches six months of age, it is time to introduce sunscreens. Choose a broad-spectrum, water-resistant sunscreen with an SPF of at least 30. Look for ingredients like zinc oxide and titanium oxide, which are generally recognized as safe and effective by the U.S. Food and Drug Administration (FDA). These sunscreens create a protective barrier on the skin, rather than needing to be absorbed, and are therefore less likely to irritate a baby's sensitive skin.

Apply sunscreen to all exposed areas, such as the back of the hands, face, ears, and neck, and be sure to apply it 30 minutes before going outside. Reapply every two hours or more frequently if your baby is swimming or sweating. Even with sunscreen, continue to use other protective measures, such as keeping your baby in the shade and dressing them in protective clothing.
