Australian sun advice now recognises that skin cancer risk and vitamin D needs vary between adults. A 2024 statement sets out three broad risk groups. It does not give everyone a fixed number of minutes to spend in the sun. For outdoor sport, the practical starting point remains the local UV forecast and suitable protection.
What changed in the 2024 advice?
The earlier message often treated every Australian adult alike. The revised position statement, endorsed by Cancer Council Australia and other organisations, considers skin type and other skin cancer risks. Its advice is for adults; children's sun protection needs separate guidance.
The three groups have different advice:
- Highest skin cancer risk: People with very pale skin that burns easily, or other major risk factors, need strong protection. Risk factors include previous skin cancer, family history of melanoma, immune suppression and many unusual moles. The statement advises discussing vitamin D with a doctor rather than deliberately seeking strong sun.
- Intermediate risk: People with olive or pale brown skin and no other major risk factors still need protection when UV is high. The outdoor time relevant to vitamin D varies by season, location, time of day and exposed skin.
- Lowest skin cancer risk: People with deeply pigmented brown to black skin have a higher risk of vitamin D deficiency. Routine protection may not be needed for short everyday exposure, but protection matters for extended outdoor time, especially when UV is high.
These are broad adult groups, not a way to diagnose your own vitamin D level. Skin tone alone cannot settle every personal risk. Ask a health professional if you are unsure which advice fits, especially if you have a skin cancer history or other risk factors.
What should you check before outdoor sport?
Check your area's UV forecast, rather than judging by heat or cloud. The SunSmart app shows local sun protection times. Cancer Council's sun guidance recommends covering clothing, a broad-brimmed hat, shade, sunglasses and SPF50 or SPF50+ sunscreen when the UV index reaches 3. For prolonged outdoor activity, plan protection even if you usually need little during brief trips outside.
For a longer training session or match, make a simple plan:
- Choose a lower-UV time or shaded venue where possible, without treating cool or cloudy weather as proof that UV is low.
- Cover exposed skin and use broad-spectrum, water-resistant SPF50 or SPF50+ sunscreen. Cancer Council advises applying it before going out and reapplying sunscreen every two hours, or after swimming, sweating or rubbing it off.
- Check whether the organiser provides shade and allows protective clothing or hats that fit the sport.
If you are choosing a walk, run or team session, consider a time with lower UV when possible. The Australian Institute of Sport's sport statement also asks organisers to consider shade, session timing and protective uniforms. When looking for an activity, use KeepActive's group finder to compare nearby options, then check the organiser's current session details.
Is there a fixed time for vitamin D?
No single time works for everyone. The position statement says skin type, location, season, time of day and the area of uncovered skin all affect the answer. People at high skin cancer risk should discuss their vitamin D needs with a doctor instead of deliberately seeking strong sun. Anyone unsure about their own risk can ask a health professional for personal advice.
