With daylight savings cutting our days shorter overnight, it’s made me think more about the light therapy box my dad would set up in our computer room (#1990s) to help with his Seasonal Affective Disorder (SAD) a lot lately. I just moved from LA to a city that experiences actual seasons and I can feel the colder, darker days affecting my mood—so I took a cue from my dad, and started looking into SAD light therapy lamps, which can help offset the effects of SAD, which is season-specific and creeps up as the days succumb to winter. Symptoms can include low energy, social withdrawal, and sleep issues.  It’s estimated that around six percent of people in the U.S. experience SAD.

How do SAD lamps work?

Essentially, SAD lamps or light therapy may help boost serotonin levels. “There is substantial data to suggest that light therapy will be beneficial to those with SAD, in terms of improvement of symptoms,” says Michael Breus, PhD, sleep advisor for Napjitsu, a new supplement line working to help people be more energized and focused using time-released caffeine and nootropics. “There are a few theories that are thought to be at play with this particular type of therapy: consistent therapy (timing of administration) will lead to help align your circadian rhythms, the therapy itself is thought to affect serotonin production and balance it (many people with any form of depression will have serotonin issues), and it increases alertness.”

What to look for in a SAD lamp

That said, you can’t just flip the switch on any old light to get the benefits—it’s important to look for products designed for SAD treatment, Dr. Breus says. “Getting just a general lightbox is not a good idea here. The biggest concern is UV light exposure. SAD lightboxes should be designed to filter out most or all UV light,” he explains.

He also recommends looking at how bright the light is, as current clinical guidelines recommend 10,000 lux or the equivalent. In addition, you want to look at if it can cause eye damage. “Some lightboxes are designed with special eye safety features which could be helpful (timers, etc), and you should check with your doctor especially if you have any eye issues,” Dr. Breus says. And, when it comes to light therapy boxes, bigger is usually better because you don’t have to sit as close to the light to get the full 10,000 lux dosage. Studies have found that positioning the lamp at a 45-degree angle from the eyes for 30 minutes can help in treating SAD, and a clinical trial also found that the best time to use one of these lamps is first thing in the morning.O

In addition to light intensity (at least 10,000 lux), Swathi Varanasi, MD, an integrative medicine specialist recommends looking for something that’s UV-free, as UV light can be damaging to the eyes and could provide more harm than good for SAD patients and a surface area that’s minimum 30-50 cm). You should also try to make sure the lamp has adjustable angles, as it’s not ideal to look directly into lamp, but rather have it perched a bit higher than eye-level and facing downward (much like the sun).

Vanessa Osorio, a sleep expert and Certified Sleep Science Coach at Sleepopolis, adds to look for lamps that have different brightness levels so it’s easy and convenient to adjust when needed. Also double check the specifications. “Some light therapy lamps are designed for other things, such as skin disorders, rather than SAD, so make sure you buy one that is specifically designed to treat SAD,” she says.
