Sunscreen in Winter: Why Sun Protection Matters All Year Round

Cooler weather can make UV exposure feel less noticeable, but temperature and UV levels are not the same. In Perth, UV levels can remain elevated during winter and may still reach the range where sun protection is recommended, even on mild or overcast days.

 

Australia records some of the highest UV levels in the world, and the UV Index frequently reaches 3 or above throughout the year. This is the level at which Cancer Council Australia recommends sun protection, which means sunscreen and other sun safety measures are relevant well beyond the summer months.

 

 

Why Winter UV Is Still a Real Risk

It is easy to associate UV exposure with heat, but a cool or cloudy day can still result in meaningful UV exposure. Over time, this exposure contributes to cumulative damage in the skin over time.

 

UV exposure can contribute to:
• Premature skin ageing and sunspots
• Eye damage, including cataracts
• Suppression of the immune system in the skin
• Long-term increased risk of skin cancer

 

Australia has one of the highest rates of skin cancer in the world. Staying protected year-round, not just in summer, is one of the most important things you can do for your long-term skin health.

 

 

Choosing the Right Sunscreen

With a wide range of sunscreens available, understanding what to look for can help you choose a product that suits your daily routine.

• SPF Rating
In Australia, sunscreens are regulated by the Therapeutic Goods Administration (TGA) SPF 50+ is the recommended standard for everyday use and filters approximately 98 % of UV radiation when applied correctly.
• Broad Spectrum Protection
Look for sunscreens labelled broad spectrum, which protect against both UVA and UVB radiation.
•Water Resistance
If you are outdoors, exercising or sweating, a water-resistant sunscreen can help maintain coverage between applications.

 

 

Mineral vs Chemical Sunscreens

• Mineral sunscreens (containing zinc oxide or titanium dioxide) sit on the skin's surface and reflect UV rays. They are a good option for sensitive skin.
• Chemical sunscreens absorb UV radiation and convert it to heat. They tend to be lighter in texture and are popular for daily wear under makeup.

How to Apply Sunscreen Properly

Even a high‑quality sunscreen may not provide the expected level of protection if it is not applied correctly. In practice, many people apply less than the amount required to achieve the labelled SPF. To help ensure effective protection, sunscreen should be applied generously and evenly to all exposed skin, in accordance with the product directions.

• Apply SPF 50+ sunscreen 20 minutes before going outdoors
• Use approximately one teaspoon per body part (face and neck, each arm, each leg, front torso, back torso)
• Reapply every two hours, or immediately after swimming or towel drying
• Don't forget commonly missed spots: ears, back of the neck, tops of feet and hands


Sun Protection Beyond Sunscreen

Sunscreen is only one part of a broader sun protection approach. Additional measures can help reduce overall UV exposure when spending time outside.

• Wear protective clothing, including long sleeves and a hat, when UV is elevated
• Seek shade during peak UV hours where possible
• Wear UV-protective sunglasses to protect your eyes year-round
• Check the UV Index daily using the free SunSmart app from Cancer Council Australia for real-time UV alerts for your location
