The debate continues about Vitamin D (the so-called 'sunshine vitamin as it is manufactured under the skin after exposure to UV light) and health (https://www.theguardian.com/science/2018/mar/09/is-vitamin-d-really-a-cure-all-and-how-should-we-get-our-fix). In less sunny locations (e.g. winter in the UK), producing enough of your own vitamin is problematic, leaving the diet (mainly oily fish) and supplements as the only easy alternative means of getting sufficient. Having a darker skin; wearing heavy clothing or covering oneself with high factor sun-cream (to avoid skin cancer) all reduce the efficacy of sunshine and being vegan limits increasing the vitamin via the dietary route. Given that vitamin D has now also been claimed to reduce the risk of cancers (in addition to the longer-established health benefits), some people are now suggesting that supplements should be more commonly employed (especially by groups of people with likely deficiencies).
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
