Vitamin D

There are both benefits and risks to sun exposure. A balance is needed between adequate vitamin D levels and increased risk of skin cancer.

Sensible sun protection (slip, slop, slap and wrap) is unlikely to put people at risk of vitamin D deficiency.

Recommendations:

1. From September to March most people should be able to achieve adequate vitamin D levels through usual outdoor UV radiation exposure outside peak UV times. Deliberate exposure at peak UV radiation times (11am to 4pm) is not recommended because this increases the risk of skin cancer, eye damage and photo aging.
2. Some people have increased risk of vitamin D deficiency eg, the elderly or those who are housebound or in institutional care. Extra measures to achieve adequate vitamin D status, such as dietary supplementation, may be required. Talk with your doctor about your vitamin D requirements.
3. People with higher risks of skin cancer need to have more rigorous sun protection practices. Talk to your doctor about your vitamin D requirements.
4. People who have darker skin are at higher risk of vitamin D insufficiency and a lower risk of skin cancer. Talk to your doctor about your vitamin D requirements.
