BBC Business reporter Caroline Hepker demonstrates some of the best new tech from London’s wearable tech show (which we attended) including SunFriend.
The financial times also recognised SunFriend as a potentially lifesaving device; “The SunFriend UVA+B Monitor is a rare example of wearable technology that could save you, or more likely, your children, from skin cancer, and should therefore be taken very seriously” wrote consumer tech journalist Jonathan Margolis.
He went on to explain that “what I especially like about it is that it acknowledges the often-forgotten need for sunlight, as well as the danger of overexposure. SunFriend uses miniature UV sensors developed, it is claimed, as part of the US space programme and aims to help people get as much sunlight as is good for them, based on their skin colour and sensitivity, while avoiding the risk of burning. It reads your exposure all day, not just from direct sunlight, but from reflected surfaces and even any UV that finds its way indoors. It is also waterproof to 3m, so perfect for the beach, and is endorsed by the Vitamin D Council.”
We all enjoy the sun but why do we need vitamin D?
Those aged between 1 and 70 require 600 IU (international units) of vitamin D a day, and those over 70 need 800 IU. If you are suffering a vitamin D deficiency you may experience a change in your skin colour, your mood and your cognitive function. Furthermore a lack of vitamin D puts you at greater risk of death by cardiovascular disease, cancer, osteoporosis, rickets (soft bones) and type 2 diabetes, to name but a few.
Dr Michael F. Holick M.D PhD explained that sunlight provides up to 90% of our daily vitamin D. whilst it is essential to expose your skin to sunlight and get outside regularly, it is paramount that you don’t over expose your skin and cause more harm than good.
It is important to note that those with darker skin need longer in the sun than those with light complexions to make the same amount of Vitamin D. If you’re not sure how long your skin tone should be exposed to sunlight SunFriend will inform you. After setting your skin sensitivity level, you can enjoy the sun assured that SunFriend will alert you when you’ve received adequate vitamin D exposure.
Open your coffin, pull back the blinds and safely soak up the sunlight with SunFriend.
