So today's blog post is most definitely inspired by the blazing sun. With today's abundance of sunshine, we wanted to highlight the importance of Vitamin D for the human body.
Now whereas the sun is most definitely a source of Vitamin D for us, did you know that it is estimated that almost 1 in 2 people in Europe is estimated to be deficient in Vitamin D. On a side note, the WHO estimates there are almost 2 billion people worldwide with a micronutrient deficiency, just let that sink in.
Whilst we have become more civilised, we have moved from working outdoors to indoors. We dress more as have no faith in the sun holding out and wear sunscreen to protect from harmful exposure. Gone are those days when children would happily play out in the streets after school. Even if we do get some sun, much of it can be lost in the smog in our cities! Put simply, the modern lifestyle is not conducive to Vitamin D generation.
Whilst the single most important use of Vitamin D in the human body is maintaining levels of calcium, it is vital to the following functions as well:
- Muscle function, for movement and strength
- Cardiovascular function, for a healthy heart and circulation
- Brain development
- Supporting the Immune system, helping you to fight infection
- Respiratory system –for healthy lungs and airways
On a 'sciencey' note, the sunshine does not contain Vitamin D itself! but rather its absorption into the skin sets off a chemical reaction that creates Vitamin D for the body. It Is the ONLY vitamin to be generated by the body in this way!
So this is a general reminder to embrace the sun whilst we have it! If you have the opportunity to be outdoors doing the same task you can indoors, then go! Soak up that sunshine!
