SunFriend Monitors UV Radiation Exposure From the Sun

By Lorrie Baumann

The UVA+B SunFriend device is wearable technology that monitors the sun exposure of the wearer, so that they know when it’s time to cover up or seek shelter. SunFriend, the startup company behind the product, launched it on the company’s website earlier this year and is bringing it to International CES for the first time.

The product is the brainchild of a NASA scientist with expertise in sensor devices and the idea that the sensors that he was using for space exploration could also help people (combat serious health issues such as skin cancer and vitamin D deficiency) get a healthier amount of sunshine. He partnered up with branding and business expert Karin Edgett, now the company’s CEO, and together with the help of their electronics partner CoolCAD and many others, brought the UVA+B SunFriend to market earlier this year. At CES, the company is debuting a prototype for the next evolution of the device, the SunFriend Bluetooth, which will expand the capabilities of the technology even further.

The UVA+B Sunfriend is being lauded by consumer electronics editors and the Vitamin D Council, which has hailed it as an effective device for healthy sun management. Exposure to sunshine is the major source of Vitamin D for most humans, and health researchers have identified Vitamin D deficiency as a factor in high blood pressure as well as musculoskeletal and other disorders. Optimized Vitamin D levels have even been linked to a decrease in risks for breast cancer. Inadequate exposure to the sun has also been implicated in Seasonal Affective Disorder, depression and dementia.

With the UVA+B SunFriend, you personalize your skin sensitivity level and then just wear it throughout the day. LED lights show you how your sun exposure is progressing and lets you know when you’ve reached your maximum daily dose of sunshine. You just strap it around your wrist, and a tiny sensor constantly reads the actual UV exposure you are getting and adjusts for brighter sun, reflective UV, clouds, indoor/outdoor activity, and more. It’s waterproof, so you can even wear it out by the pool or at the beach,” Edgett said. “All you have to do is check from time to time to see how you are progressing! When the indicator lights show you that you’ve reached your limit of healthier sunshine, then it’s time to cover up or go indoors.”

The device comes in five colors: Orange Citrus, Grey Mist, Blue Ocean, Green Spring and Black/Grey, and retails for $49.99.
