Be careful in the sun

Tip #10: Be careful in the sun

 

Be careful in the sun – Overview
•Sunshine on your skin causes vitamin D to be produced from the cholesterol levels beneath.
•A deficiency of vitamin D is linked to higher levels of many cancers – not more.
•Over-exposure to solar radiation is carcinogenic to humans.
•The best defenses against getting too much harmful radiation are protective clothing and shade.
•Keep infants in the shade – they lack the tanning pigments to protect their skin.
•Check your skin regularly for new moles that are tender or growing.

Ultraviolet (UV) radiation, and in particular solar radiation, is carcinogenic to humans, causing all major types of skin cancer, such as basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and melanoma. Globally in 2000, over 200 000 cases of melanoma were diagnosed and there were 65 000 melanoma-associated deaths. Avoiding excessive exposure, use of sunscreen and protective clothing are effective preventive measures. UV-emitting tanning devices are now also classified as carcinogenic to humans based on their association with skin and ocular melanoma cancers.


Sunshine protects you from cancer!

Consider these research-based facts:

* Sunshine on your skin causes vitamin D to be produced from the cholesterol levels beneath.
* When part of your immune system (a T-cell) finds a rogue cell in your body, the first thing it looks for is a vitamin D molecule to ´activate´ it.
* A deficiency of vitamin D is linked to higher levels of many cancers, and also to other diseases from simple colds to osteoporosis. Vitamin D is a cancer preventer.
* There are several studies which show that over 90 per cent of people with melanoma are deficient in vitamin D. Not surprisingly they have weaker immune systems too. The fact is they haven´t had ENOUGH sun!
* Research shows people who have regular exposure to sunshine get less skin cancer, not more!
* 2009 research from Leeds University showed that vitamin D could prevent skin cancer, and skin cancer patients with higher levels of vitamin D in their blood actually survive longer!
* Possibly the most damning research comes in the Journal of Dermatology in late 2011. Firstly, the researchers conclude that grade 2, 3 and 4 cases of melanoma are not on the increase. They state that the supposed rise in such cancers are because Doctors too readily call grade 1 lesions ´melanoma´ and start treating them when there is no need – ´an artefact´ is how they describe this. Then…
* The same research report concludes that half of genuine melanoma lesions are in places on the body ´where the sun don´t go´.


“Paradoxically, outdoor workers have a decreased risk of melanoma compared with indoor workers, suggesting that chronic sunlight exposure can have a protective effect.”
The Lancet



How Sunscreen Could Be Causing Skin Cancer, Not The Sun

Published By Arjun Walia

As many of you probably already know, humans require sunlight exposure for vitamin D. Sunburns are indeed a concern, and there are many studies that link sunburns to melanoma, but due to a wide range of factors, such as cultural changes and marketing campaigns, our skin has become less resistant to sun exposure. If you spend a large portion of your time in the sun, your skin adapts to build a natural immunity. We are naturally built to receive sunlight, and we have gone backwards in this regard. There are alternative ways to protect yourself from sunburns. You can buy natural sunscreens without harmful chemicals. Questioning big name advertisements is crucial to our health in these times of information awareness.

Only 10% of all cancer cases are attributed to all forms of radiation, and UV is a very small part of that. When we think of skin cancer we automatically want to blame the sun, but what about other causes of skin cancer that are out there? Arsenic, found in a number of things we ingest or work around,  pesticides, and leather preservatives are all causes for concern.

Sunscreens are a huge contributor to toxins in the body, being absorbed within seconds of application. Is it not important to know what you are putting into your body? We now live in a culture where we fear the sun, which is ironic considering it has created all life on Earth. It’s important to remember that fear eventually manifests as reality. The sun has many health benefits, so using natural products will ensure that you receive these benefits while keeping your skin safe.


This study Beneficial effects of sun exposure on cancer mortality says:  “there is support in the medical literature to suggest that… approximately 30,000 U.S. cancer deaths yearly would be averted by the widespread public adoption of regular, moderate sunning.
