Here comes the sun – don’t run away from it!
Have you ever wondered why your mood lifts when the sun comes out? Or why it feels so good to lie outside and let your skin soak up some sunshine? It’s because the sun is so good for us! The human body needs sunlight to grow, thrive and survive. We need sunlight to be healthy.
For the past 30 years or so the sun has been the subject of much demonising. Doctors, dermatologists, health officials, beauty experts, product companies and that darn convincing ‘Slip, Slop, Slap’ bird have had us running for cover the second we feel the heat of the sun on our skin. We are well educated on the link between skin cancer and sunlight exposure, but as a result of this over-simplification of facts we have gone from one extreme to the other. We are now so afraid of burning that our bodies are becoming severely deprived of vitamin D – a hormone best sourced from the sun. This is a serious problem and it is contributing to many illnesses and diseases.
Our bodies use sunlight to help the skin produce the vitamin D it needs to build bones, suppress inflammation, strengthen the immune system and protect against cancer (including skin cancer). A research paper by internationally recognised research scientist and vitamin D expert Dr William Grant, Ph.D shows just how strong the evidence that sunlight fights cancer really is. His conclusions state that, “From a scientific point of view, vitamin D reduces the risk of developing many types of cancer and increases survival once cancer reaches the detectable stage.”
Here are my top six tips for avoiding vitamin D deficiency:
1. Get your daily dose of sun: The best way to increase your vitamin D levels is through safe, smart and limited sunscreen-free exposure to the sun. 15-20 minutes of sun exposure daily should be all you need (although this varies depending on where you live, what type of skin you have and your age). Never lie out in the sun for extended periods of time or during the hottest part of the day, always avoid sunburn and build up a tolerance to the sun slowly. If you’re fair skinned, start introducing your skin to the sun in the cooler months in the morning or afternoon.
2. Uninterrupted exposure: You cannot generate vitamin D if there is a glass window between you and the sun. The UVB rays needed for vitamin D production are absorbed by glass and will not be passed through to your skin.
3. Don’t cover up with sunscreen: Even weak sunscreens will block the ability of your skin to absorb the UVB rays and manufacture vitamin D. However, once you have surpassed your 15-20 minutes of unprotected exposure, you should get out of the sun or cover up with something. If you do need sunscreen, find one that contains no chemicals. Visit the Environmental Working Group to find the safest products.
4. Protect your skin with food: Still worried that exposing your skin to sunlight is harmful? Load up on anti-oxidant rich foods and beneficial fats that will strengthen your skin cells and help to protect them from sun damage. These include vegetables and fruits such as blueberries, raspberries, goji berries and pomegranates.
5. Have your Vitamin D levels tested regularly: The best way to find out whether you are deficient or not is to take yourself along to have a blood test. If you are aiming for optimal health you will want your level to be in the 80-150 ng/ml range.
6. Take a supplement: During winter or if you live in an area that gets minimal sun exposure, you may need to source a vitamin D3 supplement. Be careful with this though because taking too large a dose can lead to vitamin D toxicity. This is why sunlight is the best source of vitamin D, as the body will only take and generate what it needs. If you think you need a supplement, check with your doctor or naturopath first and have your vitamin D levels checked regularly to ensure you are not getting more than you need.

Have you had your vitamin D levels tested? Do you think you get enough vitamin D? How often do you get out in the sun?
Positive affirmation for the day: The quality of my life is determined by the quality of my thoughts. If I change my mind, I can change my life.
