Frequently Asked Questions :
What is SunSprite?
SunSprite is the first solar-powered wearable device that measures and tracks the amount of sun and light that a person is receiving. In its most basic form, it reminds you to get outside and absorb bright light, which wakes up your brain and makes you healthier!
SunSprite also syncs with its mobile app via Bluetooth Smart to give you personalized tracking updates and coaching tips based on medical science.
What are the benefits of bright light?
Dozens of scientific studies prove that the right amount of bright light exposure increases energy and focus, improves mood, and helps you sleep better. People who get their bright light report that it’s not only easier to get out of bed in the morning, but also that they don’t feel groggy when waking up. In fact, bright light wakes up your brain as well as coffee does (but without the caffeine addiction!).
One study even found that adding morning bright light to a weight control program helps reduce body fat and appetite.
How does SunSprite work?
SunSprite uses patent-pending technology to track and record the amount of bright light exposure you receive each day. It takes these measurements and breaks them down into units friendly to you, “GoodLux.” This allows you to effectively track your bright light exposure for the first time.
SunSprite uses Bluetooth Smart to transmit your light exposure data to your mobile phone, where its app helps you analyze your patterns and learn how to optimize your bright light exposure.
What kind of light does SunSprite measure?
SunSprite measures both visible and UV light. No other product monitors both of these for everyday use.
When would I start to feel the positive effects of bright light?
When will I get positive effects?
Most people feel the effects after just a few (3–4) days. Our mobile app makes it simple to understand how much light you need and how to get it.
How does SunSprite know how much bright light I need?
How much light do I need?
SunSprite’s recommendations are based on over 25 peer-reviewed scientific studies that have identified a “gold standard” of bright light (click here to read our white paper). This gold standard (10,000 lux for 30 minutes each day) has been shown to be so powerful that it even relieves symptoms of depression and insomnia. It’s as simple as taking a half-hour walk outside in sunshine, or spending time near a sunny window.
We’re sure you’re asking: what is 10,000 lux? It’s about the brightness of a slightly overcast day, but since sunshine, shade, and cloud cover can vary dramatically, we suggest wearing your SunSprite to accurately gauge your exposure.
The best part about SunSprite is that it does all the work for you—continually adjusting its calculations as you move through brighter or dimmer light, while always letting you know how close you are to hitting your daily goal.
If I don’t have time to get outside, what can I do to get enough bright light?
What can I do to get more light?
There are plenty of ways to make bright light part of your everyday life. If your job or schedule does not allow for outdoor time, here are some simple steps you can take to increase your bright light exposure:
When indoors, sit in a sun-filled room facing a window. Whether it’s eating breakfast, reading a book, or sitting in a meeting, a sunny room is your best bet.
If work allows, take your lunch break outside.
If possible, set your alarm 30 minutes earlier in the morning and go for a nice walk.
If you need additional bright light, consider purchasing a light box (also called a light lamp). We’ve got you covered – SunSprite accurately tracks your light exposure from both the sun and light boxes.
Does SunSprite work with light boxes?
Yes. The most concentrated bright light comes from the sun; however, using light boxes can be a great way to supplement your daily intake.
SunSprite also increases your light box’s overall effectiveness by measuring how much bright light you’re getting from your light box, accounting for its intensity, effectiveness, and distance to your eyes (suffice it to say, not all light boxes are the same).
So whether it’s from a light box or the sun, SunSprite makes it easy to track your daily bright light exposure.
Can I get the benefits of bright light while being indoors?
Yes, and this is one of the most convenient ways to use SunSprite. Almost all of the sun’s visible light passes through normal window glass. So when you’re just sitting at home or in a meeting at work, try to pick a sunny room and grab a seat facing the window.
Where’s the best place to clip my SunSprite?
We designed SunSprite’s flexible magnetic attachment to be strong enough that you can wear it anywhere. It’s best to clip it to your “strike zone”—a spot on the front of your body between your eyes and pockets.
A few ideas: on a collar, sleeve, pocket, or a lapel, as an accessory – it’s easy to put a chain through SunSprite and wear it as a pendant or wristband. Plus it is also designed to attach to purse straps, backpacks, or hats.
Does SunSprite work when it isn’t bright daylight (e.g., winter, cloudy day, rainy day, dawn, dusk)?
Yes, SunSprite continually calculates your exposure no matter what conditions you are in. Even if the sun goes behind the clouds, SunSprite tracks it all. The brighter the sun, the higher the lux (and the happier the SunSprite!). 10,000 lux (the brightness of a slightly overcast day) for 30 minutes early in the morning is the typical gold-standard dose.
How do I see my data and check my progress?
SunSprite has two ways to show your progress. When you press the button on the front of your SunSprite, a series of lights will illuminate on the front face. There are 5 total LED lights, so if 3 light up, you know you’re 60% of the way to your daily goal.
SunSprite also has a mobile app that syncs with your phone (currently iOS) via Bluetooth Smart. Our mobile app shows your progress along with much deeper analytics and also provides coaching tips.
How do I replace my SunSprite battery?
SunSprite is powered by an easily available 1632 coin cell battery. To replace the battery, open the battery door (located on the back of the SunSprite) by using a coin to turn the slot on the door from locked to unlocked. The magnetic clasp can be used to lift the door once it is unlocked and the battery replaced.
Is SunSprite waterproof?
SunSprite is water resistant but not waterproof. It shouldn’t be worn while swimming or showering. It is, however, rain, splash, and sweat-proof. So go and enjoy that run!
How big is SunSprite?
About 1” x 2”, similar to the size of a baby carrot.
How much does SunSprite weigh?
SunSprite is light enough that attaching it to your shirt or sweater won’t cause your clothing to droop.
Is there an ideal time of day to get my bright light exposure?
For best results, we recommend you receive your bright light within two hours of waking up. This not only helps you start off your day in an awake, engaged and alert state, but also sets your brain’s sleep hormones so that at the end of the day, it’s easier to fall asleep and get a good night’s rest.
The SunSprite mobile app also provides personalized coaching on the best time of day for you, based on your wake/sleep schedule.
Is there a time of day I should avoid bright light?
At mid-day, the sun is brightest and there is the greatest chance of sunburn and risk of developing skin cancers, so we recommend (especially if you’re fair-skinned!) wearing ample sunscreen or covering up.
At night, light impacts your circadian rhythms and too much light at the end of your day (whether from a natural source like the sun, or an artificial source like a television, mobile device or computer) can negatively impact your sleep cycle, sending signals to your brain to stay awake. That’s why it’s important to avoid sitting in front of bright screens before going to bed.
Can bright light exposure offset the need for prescription drugs (e.g., Prozac)?
Absolutely. There are 25 scientific studies (conducted since the early 1980s and continuing today) that substantiate the effectiveness of bright light therapy as an alternative to pharmaceuticals. We believe that everyone can benefit from bright light – it supplements a healthy lifestyle and can improve focus and energy, as well as improve sleep patterns and cycles.
Is there such a thing as too much exposure to bright light? If so, what are the associated risks?
Can I get too much bright light?
Bright light must be received through the eyes for full effectiveness. If you have a retinal condition (e.g., macular degeneration), you should check with your ophthalmologist about bright light exposure. And if you suffer from bipolar disorder, you should speak with a doctor before bright light exposure as well.
When it comes to cognitive and psychological effects, some people may feel a bit “wired” when they begin to use bright light. This feeling usually goes away after the first few days.
Beyond issues related to the eyes, overexposure to sunlight can also cause sunburn and skin damage. The effect of bright light on energy, focus, mood, and sleep is related to light absorbed through the eye and not through the skin, so it is perfectly fine to wear sunscreen while outside and still receive these benefits. We recommend you speak with your doctor about the use of sunscreen when in bright sunlight, and follow the instructions on your sunscreen packaging for proper application.
Does SunSprite warn me if I’m getting too much sun?
Do I get warned about too much sun?
SunSprite can tell you the current UV intensity and can warn you when it’s intense enough to cause sunburn. However, because of differences in skin type, SunSprite does not make recommendations on avoiding sunburn.
Can I wear sunscreen and still benefit from bright light?
Sunscreen and bright light benefits
Absolutely. Bright light therapy is not about ultraviolet (UV) light absorbed by the skin; it’s about visible light received through the eyes. UV light is not visible.
Can I wear sunglasses and still benefit from bright light?
Sunglasses and bright light
Yes, on a bright, sunny day.
Can I wear prescription glasses with UV lenses and still benefit from bright light?
Can I Wear Prescription Glasses With Uv Lenses And Still Benefit From Bright Light
Yes. Non-tinted glasses block UV but do not significantly change the brightness of visible light reaching your eye, so SunSprite will still be able to accurately measure your visible light exposure. Wearing non-tinted glasses is similar to sitting at a window.
Does SunSprite measure Vitamin D production?
No. We currently do not make any recommendations about Vitamin D because the production of Vitamin D by your body depends on UV absorption by your skin, which is affected by both skin type and percentage of skin exposed to the sun.
Where is SunSprite manufactured?
The electronics were designed in California, and the case was engineered in Massachusetts. We’re proud to say that SunSprite is fully manufactured and assembled in the US.
