Strength of the sun is #1 Factor for Safer + Healthier Sun Exposure. June 19 2015
Here are the most important steps to determining how much sun is healthy vs how much sun will be dangerous:
#1 Intensity of the sun
Scientists and doctors agree around the world that the most important factor in determining appropriate sun exposure is the UV Index, or how intense the sun is. Everything else is based on this important first step. What SPF sun block and clothing you choose is based on this knowledge.
The UV Index is an internationally recognized scale for the intensity of the sun - or how much Ultraviolet radiation is getting from the sun, through the atmosphere (clouds and pollution and humidity) to your skin. Until now, you had to rely on hand-held UV monitors or data from far away weather stations that may not represent your exact conditions.
Now it is easy to find out how strong the sun is.
UVA+B SunFriend is the first patented wearable UV monitor that will read the intensity of the sun right where you are, taking into consideration all atmospheric conditions.
By facing the SunFriend directly at the sun and counting to 8 and then push the UVI button and it will tell you the UV Index or strength of the sun right where you are.
SunFriend's sophisticated sensor reads UVA and UVB contained in the atmosphere and picks up reflected UV from water and snow.
#2 Color of your skin
Skin color or melanin, represents your personal level of natural protection or blocking of Ultraviolet radiation. The more you have, the harder it is for the sun to penetrate your skin. Which is a good thing if you are trying to avoid a sunburn and a bad thing when you are optimizing your natural vitamin D.
This is the second most important factor for balancing sun exposure for both wellness and safety.
You choose your sensitivity level, SunFriend calculates how much time you have in the sun.
When you are wearing your SunFriend, you can choose your skin color based on this chart.
Other factors, such as medications, diet or general wellness, and the type of activity you preform may also effect your body's natural level of sun protection. If you are unsure of your level, please start with a lower number and if you don't turn pink or red at all during your day, you can add another level or number the following day.
SunFriend automatically adjusts the time as conditions such as clouds, breaks in the shade or your activity level changes.
Once you have determined these two factors, you can safely be in the sun for limited amounts of time. This is the best way to help boost your vitamin D levels and the host of other healthy benefits of "whole sun" exposure while lessening the risk of skin damage.
If you choose to stay in the sun longer, it is extremely important to cover up with UV blocking clothing, wear the best Broad Spectrum sunscreen available or get into the shade!
People get a healthy amount of sun, but never ever burn. Sunshine contributes to our wellness in many ways, from vitamin D to helping us grow strong to nitric oxide which lowers our blood pressure to making us feel happy. Scientists have spent a lot of research on what happens when we have too much sun, and are just now beginning to understand what happens when we have too little sun.
SunFriend helps you understand the most important two factors for balanced sun exposure - Intensity and Skin Color. It will keep track of how much sun you get each day and flash when you have had enough, but not too much. It is a wonderful tool for teaching children and young people how to become more responsible in the sun and establish early habits that may benefit their entire life's well-being.
