For healthy development, your child needs to have a small amount of exposure to the sun. This can be as little as 10-15 minutes per day. Baby skin burns much more easily than adult skin, so taking care in the sun is important. Because of high exposure to UV radiation, Australia has the highest rate of skin cancer – a cancer which can spread rapidly around the body – in the world.
You don’t have to sit in the sun to be exposed to UV radiation. You can get burned on a cloudy or cool day, or if there’s sun reflecting on to you from buildings, water, sand or snow.
UV radiation is strongest between September and April, between 10 am and 3 pm. If you can, save trips to the playground, the park or the beach for early morning and late afternoon.
Sunscreen combined with clothing and shade is the most effective way to keep your child safe from the sun and its reflection from water, sand, snow and buildings.
You might have heard that children will get Vitamin D deficiency if they don’t play in the sun often enough. In Australia – with our long days and high levels of UV radiation – most children get more than enough Vitamin D from reflected sunlight. (Although recent medical research tells us that people with dark pigmented skin require longer daily exposure to sunlight to absorb Vitamin D.)
Some people might tell you that the best cure for nappy rash is direct sunlight. Fresh air will definitely help nappy rash, but putting your baby in direct sunlight is likely to burn her.
Recently, researchers have been looking at whether sunscreens harm babies younger than a year (most authorities don’t recommend sunscreen under the age of 6 months). They have studied whether a baby's thin skin can absorb chemicals from sunscreen, which might damage the baby’s organs. They have concluded that if you use only small amounts of sunscreen on uncovered areas such as the face and hands (that is, rely on clothing to cover most of the body, rather than slathering your baby’s legs, arms and body in sunscreen) the tiny amount of sunscreen which may be absorbed shouldn’t be enough to harm your baby.
