**A New Approach to Combat Indoor Living: The Sunbooster SLS2000 Infrared Light Device** According to the Environmental Protection Agency (EPA), we spend approximately 90% of our time indoors. To combat this trend, various products have emerged to mimic the outdoors indoors. One such product is the Sunbooster SLS2000, a $265 device that attaches to a laptop to emit infrared light throughout the day. The Sunbooster SLS2000 was unveiled earlier this year at the Consumer Electronics Show (CES) by SunLED, the company behind the device. Designed for desk-based workers and those living in areas with long winters, the Sunbooster mimics the sun's rays without the actual light. The device emits near-infrared (NIR) light through three LEDs and features a motion sensor to calibrate the right distance before administering the light, as NIR light can be harmful if it's too close. The benefits of NIR light are similar to those of being in the sun, according to SunLED. These benefits include improved mood and reduced drowsiness. A 2022 study found that NIR light can have beneficial effects on humans during winter, but its findings were skeptical about the efficacy of products like the Sunbooster. The study stated that indoor NIR irradiance from general lighting conditions is at least 100 times lower than direct sunlight, which may be too low to induce an appreciable biological benefit. As a desk-based worker, I tested the Sunbooster to see if it could boost my energy and mood throughout the workday. The device was easy to set up, requiring only a quick USB-C connection to my laptop or monitor. After setup, it took around three hours to reach 100% NIR intake completion. However, this time frame may not feel long if you're working at your computer all day. I tested the Sunbooster during the dark days of winter in the northeast, but I couldn't definitively say whether it boosted my mood. I did feel like I was doing something good for my health by using the device. A doctor I spoke to about the science behind infrared light expressed skepticism about the need for a device like the Sunbooster, citing the potential health risks and lack of supporting medical evidence for its claims.
