Use SunFriend to get enough sun every day

  • The best-known benefit of sunlight is its ability to boost the body’s vitamin D supply; most cases of vitamin D deficiency are due to lack of outdoor sun exposure... read more on our Sun+Health Connections page. Sunshine provides long-lasting vitamin D, plus the sun will help lower your blood pressure, enhance your mood and bring your overall wellness into balance.

    Vitamin D is most prevalent during the summer months during the middle of the day. A great way to make sure you are optimizing your vitamin D levels is to use the SunFriend when your shadow is shorter than you are! Shorter shadows indicates more prevalent UVB wave lengths – the ones that are responsible for vitamin D. 
  • Use the SunFriend at lunch time or on walks or during outdoor workouts to optimize your wellness. 
  • Use SunFriend's NASA inspired technology to read the UV Index and know how intense the sun is right where you are. This can help you decide what sunscreen to wear after you have reached your healthier sun exposure. 
  • SunFriend is a super tool for teaching children, who need the sun to grow healthy bones among other things. Use it to explain when they have not had enough sun as well as when it is time to cover up or get inside! Or when to put on sunscreen. 
  • Doctors and medical professionals can use SunFriend to replace the adage of spending 15 minutes in the sun each day with real advice with NASA based science and internationally recognized standards for skin color settings, UV Index and current atmospheric conditions. SunFriend exposure readings are not guesses, but real-time data based.

    UVA+B SunFriend® Sun Monitor Instructions:

    Turn ON each day to start daily UV/Sun accumulation.

    Select your Skin Sensitivity by holding down the Set Sens button. 1 is for the lightest, and/or most sensitive skin and 11 is for the darkest, and/or least sensitive skin.  Start with lower numbers 1-4. As you become familiar with your own sensitivity, adjust the number accordingly. Hint: If you experience reddening of the skin after all 11 LED's have lit up, set your SunFriend® Skin Sensitivity to a lower number the next time you use it.

    Wear SunFriend face-up on your wrist throughout the day. Make sure the face is unobscured by clothing. Push the Check UVA+B button from time to time to see how your sun exposure is accumulating. When all eleven of your LEDs light up and are Flashing, you have had your UV/Sun exposure for the day. 

    When flashing, turn OFF. It is time to apply sunscreen and/or sun-block clothing, or to go indoors. Turning SunFriend off also resets it for a new daily exposure. Hold the on/off button for at least 2 seconds, until the lights power down.

      See the SunFriend® instructional video for additional information.

        Setting your sensitivity level is a personal experience. Factors that affect you may include skin color, diet, activity type, medications, and regularity of sun exposure. If you set the number too high, you may see reddening of the skin. If this occurs, set your SunFriend Sensitivity to a lower number. When you are trying to get a safer, healthier amount of sun, you do not want the skin to redden. SunFriends are also not intended for use in tanning beds.

        Instructions for checking the UV Index so you know how strong the sun is. 

          1. Align center of SunFriend directly with the sun for at least 10 seconds
          2. Press UVI button and wait for the light to indicate the UVI

          Please note: The sensor takes a reading from your environment every few seconds, and also reads reflective UV. Pointing it directly at the sun for less than 8 seconds may not give you an accurate initial UVI reading, but that does not mean your SunFriend is not fully sensing all of the environmental UV you are being exposed to. Customized algorithms allow for varying movement, reflective UV, and actual weather conditions to provide you with an overall safer amount of UV exposure regardless of the UV Index reading you get from your SunFriend©.

          The UV Index is an international standard measurement of how strong the ultraviolet (UV) radiation from the sun is getting through the ozone and atmospheric conditions such as clouds and smog.
