Can Sun Cream Cause Prickly Heat Rash?

Heat rash, often referred to as prickly heat or miliaria, is a common and uncomfortable condition in both children & adults, especially in the warmer months. Understanding the causes of heat rash and knowing how to prevent it, especially when using sun cream, is essential to ensure the well-being of the children in your care.

What exactly is heat rash?

Heat rash occurs when sweat gets trapped in the skin, causing tiny red bumps or blisters. This can lead to itching, discomfort, and sometimes a prickling or stinging sensation. In young children, whose sweat glands are not yet fully developed, this condition can be particularly troublesome.

So, what causes this uncomfortable rash, particularly in the context of sun cream use?

Several factors contribute to the development of heat rash in children. The primary cause is excessive sweating, which can occur in hot and humid weather or when children are overdressed. Sweat glands can become blocked, trapping sweat beneath the skin. This blockage is often exacerbated by tight clothing, heavy fabrics, or lack of ventilation. Additionally, certain areas of the body, such as the neck, back, chest, and nappy area, are more prone to heat rash due to friction and limited airflow.

Sun Cream, while essential for protecting children's sensitive skin from harmful UV rays, can sometimes contribute to the development of heat rash. This happens because some sun creams can create a barrier on the skin, making it more difficult for sweat to evaporate. This barrier effect can be particularly problematic if the sun cream is thick or oily.

So, how can we balance the need for sun protection with the need to prevent heat rash?

One major step is to choose the right type of sun cream. Look for formulations that are specifically designed for children and labelled as "non-comedogenic" or "breathable." These types of sun creams are less likely to block pores and allow the skin to breathe. Gel-based or mineral-based sun creams are often better choices as they tend to be lighter and less occlusive than their creamy counterparts.

Application technique also matters. When applying sun cream, use a thin, even layer rather than slathering it on thickly. This helps to ensure that the skin can still breathe and that sweat can evaporate more easily. Reapply sun cream as necessary, especially after swimming or sweating, but try to avoid excessive build-up by wiping the skin with a damp cloth before reapplication.

Sun Cream Hack

For a smoother and more even application, try using a makeup brush to apply sun cream. This technique helps spread the product evenly across delicate areas of the face, ensuring thorough coverage without the mess of using your hands.

Another important factor is the timing of sun cream application. Apply sun cream at least 15-30 minutes before outdoor activities to allow it to fully absorb into the skin. This not only ensures effective sun protection but also gives the skin time to adjust and reduces the risk of blocked sweat glands.

Keeping children cool is another vital measure to prevent heat rash when sun cream is applied. During hot weather, encourage play in shaded areas or indoors where it's cooler. Ensure that indoor spaces are well-ventilated and, if possible, use fans or air conditioning to maintain a comfortable temperature. Frequent breaks from physical activity to cool down and hydrate are crucial. Providing plenty of fluids will help regulate body temperature and prevent dehydration, which can exacerbate heat rash.
