I have always had this doubt regarding vitamin D which is best absorbed by human body from direct sunlight. Many of us however miss it. Even those of us who have scope for sun exposure sadly dab the SPF(Sun Protection Factor) creams of various strengths ranging from 15-20 to 60-70 (in case of those who have to be under direct sun for hours in tropical climate). Since I am a home bird, I have never had much of use for the SPF sunscreens. Also I am out of touch with the cosmetic world. I go for a few known brands whose produce are not tested on animals. Plus I am missing out the beauty routine as I am not the salon person. All these put me in fix and I have no idea on anything when it comes to grooming. My friend’s young daughter of 22 recently advised me that, even at home I need the SPF protection as I am exposed to ultraviolet rays from my desktop/laptop and mobile phones. Also I spend hours close to my window. Although there is no direct sunlight filtering in, she said I may still be exposed to the uv rays that infiltrate the atmospheres. I wondered whether vitamin D from sunlight is better and healthy choice, or the protection of our skin from ageing because of uv rays of the sun is! As I am mostly based in middle east whether temperatures can hit 50 c easily in summers, I do make it a point to apply a coat of sunscreen whenever I go out. I leave it to my exposed arms to soak in the vitamin D, saving my face and neck from the job! However, whenever I have to wear full sleeves, I rue the fact that not a square inch of my skin is open to sunlight. After all, sun light is the best and natural source of vitamin D and it comes free! I wondered whether my exposed crown and scalp can absorb the vitamin D for me! Can nails and hair that are external growth without nerve endings absorb anything at all, even something as finer as the rays of the sun? I googled for information but there is no satisfactory answer. The search results all summarize that loss of vitamin D can lead to hair fall. Anyway, this is also news to me! But my question is different. I just want to know whether my scalp, my hairline or my crown may be capable of absorbing the vitamin D from sunlight. Thanks to some indoctrination on importance of sunscreens, nowadays i am habituated to moisturizing my face and neck with at least a weak SPF cream that I never used to until a couple of years back. In cold weathers, I have no option but to wear full sleeves. I wonder whether my scalp and hairline are doing some OT (overtime) work for me in the circumstances when it comes to vitamin D absorption! Just a thought lolz. I wouldn’t really bother about a tan. Bleaching which is staple with most women where I come from, is ruled out for me as I can’t stand the whitening treatment. So I have to balance my sun exposure and vitamin D soaks. Any day vitamin D wins hands down! Still if anyone can assure me that my scalp/hairline/crown can absorb vitamin D for me, I will feel free to lavish on SPF creams. I feel guilty for dabbing a blob from a tub of sunscreen everyday now. Am I denying myself the much needed super vitamin for after all some useless vanity. Honestly I couldn’t care less! We menopausal women have much use for vitamin D as we tend to lose our capacity to make more of this vitamin resulting in the onset of Osteoporosis. Yet, given the level of air pollution in India and the heat and the dust and the high temperatures of both India and Qatar that are sunny most part of the year, I would like to have both the protection of an SPF layer as well as my quota of vitamin D from direct sun whenever and wherever possible. If only I get credible evidence that our scalp and hairline and crown soak vitamin D, it will ease my conscience and I will feel less guilty going for the SPF. Where to find the answer to my curious questions. Nobody I have asked to, has provided me with satisfying solution. Nobody simply has any idea. I do have the habit of feeling my scalp whenever I am out in the sun with a veil of sunscreen on my face. Whenever I would feel the familiar warmth of the sun in my crown, I would wonder if that’s vitamin D that is seeping in right at the moment hahaha!!! Anyone ever wracks one’s brains to think the way I do?! All said, my friends are going for an annual course of Vitamin D therapy that is recommended to me. As most of us do not absorb sufficient vitamin D from direct sun, physicians are prescribing the 7 day vitamin D intake that I am planning to commence shortly. The procedure is to be repeated every year. Hopefully that will allow me to go easy on SPF sunscreens. A friend recently felt disoriented and the diagnosis was Vitamin D insufficiency. Ever since I am taking vitamin D much more seriously. In any case I do not go for more than SPF 25 that can last me for maximum of two to four hours after which I am open to sky when outdoors. I guess this is good material for research!
