Light therapy lamps, also called sunlamps, can bring a warm, tropical vibe to your dim, snow-covered home or office. And they have proven benefits for your state of mind: “Sunlamps replace natural sunlight when we don’t have access to it, thus replicating the physiologic (and mood) effects of actual sun exposure,” Deborah Offner, clinical psychologist told Allure. Unlike a typical bulb, they produce a full spectrum of light that mimics natural sunshine. Your brain then reacts by producing more vitamin D as well as the same feel-good hormones you might release after a day at the beach. That’s why they’re a commonly recommended tool for people with seasonal affective disorder. According to Michelle Henry, clinical instructor of dermatology at Weill Cornell Medical College, the production of vitamin D is also “important for maintaining healthy skin cells and robust hair follicles.” So whether you’re looking for a sunnier outlook or healthier-looking skin, these quality sun lamps might be able to lift you out of your winter slump.
