Sun burns, blisters, rashes, wrinkles, mutations, melanomas, oh my! The modern pharmaceutical industry is making evil out of the sun light and eagerly provides and pushes layers of creams, sun blocks, sun screens, sun lotions, you name it. Why is it then that the oldest people on our planet surviving to the age of 115, 120 and over are known to spend most of their life time outdoors without these modern sun blocking remedies? And how come the mutation that caused the color change of the human skin from dark to white (evidently allowing MORE solar radiation to pass through) had NOT been eliminated by natural selection? On the opposite: this specific change did allow human ancestors to move to higher altitudes and migrate to Europe, Asia and Northern America.
The sun has been shining for billions of years. Without sunlight evolution of life on our planet including humans would simply not have been possible. It is well known that just a few minutes of tanning makes people happier and relieves depression by the skyrocketing production of serotonin and endorphins (neurotransmitters for pleasure and euphory), as well as life sustaining amounts of vitamin D, the latter being produced not only in humans, but in all other vertebrates including fish, amphibians and reptiles. This vitamin allowed vertebrate animals to maintain their calcified skeletons as they emerged to the land from the sea water nearly half a billion years ago. So who in their right and not corrupted mind could have labeled this vital adaptive advantage as “damaging”?
Bellow is a list of some secret powers of vitamin D in the human body:
- Serves as cytokine needed for immune defense when converted to calcitriol;
- Assists the work of monocytes as well as both T and B lymphocytes of the immune system;
- Promotes healthy mineralization of the bones and prevents rickets (brittle and misshapen bones) in children and osteomalacia in adults;
- Regulates uptake of calcium and regeneration of the bones preventing osteoporosis in elderly;
- Being a fat-soluble secosteroid (steroid-like substance), vitamin D passes through the nuclear envelope and regulates cellular division and apoptosis (self destruction) at the DNA level;
- Regulates the gene expression (production) of the transport proteins involved in absorption of calcium by the intestinal walls (what’s the point of ingesting calcium containing foods if your body cannot absorb it?);
- Stimulates the work of adrenal medulla cells involved in production of nitric oxide synthase (the erection promoting enzyme).
Important to mention, however is that man made pills and fortified foods are not the same sources of D vitamin as natural sunlight exposure. We are not yet smart enough (if we ever can be) to trick the evolutionary formatted human physiology and metabolism. An artificial overdose of this important vitamin by ingestion may actually cause serious side effects like hypercalcemia, growth retardation, bone and facial fetal developmental abnormalities, metastatic calcification of kidneys and other irreversible damages. The natural sun light exposure, though needed for at least 20 min a day for light skin and up to triple that time for a darker skin individuals could NEVER cause the over dosage. Once the required amount of vitamin D is made in the skin by the sunlight, the rest is getting safely degraded.
So here is the eye opening conclusion for you, folks: that precious vitamin D producing solar radiation naturally REDUCES the chances of colon, breast, ovarian, pancreatic and many other types of cancer (in some studies by 30 to 50%), cures depression, fights the high blood pressure and cardiovascular diseases, increases the life span and reduces mortality and premature aging in the general population.
Let there always be sunshine!
It’s appropriate time to make some plans for the future and it’s time to be happy. I’ve read this post and if I could I want to suggest you some interesting things or suggestions. Maybe you can write next articles referring to this article. I want to read even more things about it!
Thank you, Janice: I am always open for new suggestions, go ahead, speak your mind! In a week I will be done with my Summer Session and continue with the blog. Thanks again for inspiring comment.
good article!
