Light Therapy FAQs
Is light therapy safe? Are there side effects? Can you do too much?
First, with an FDA-cleared device, it’s safe and comes with little to no side effects. And I’m not the only one that thinks this. A major 2013 study by Harvard and MIT researchers praised light therapy for its “noninvasive nature and almost complete absence of side effects.”
Regarding overuse, you can overdo just about anything that’s good for you, but it’s hard to get too much light therapy. I stick to 20-minute treatment sessions because the body of scientific literature says that particular energy dose is optimal and safe. But even if you did more, it’s hard to imagine a lot of negative effects.
What do you do with a light therapy device and where do you use it?
You don’t have to do a whole lot. Just use your handheld device in the grated areas for 3-5 minutes a day.
You can do it anywhere you want. I use my INFĒRA in my office so I feel rejuvenated ahead of the work day. But there’s no wrong place to do it as long as you do it regularly.
Is light therapy different from heat lamps?
Yes, and the answer is right in the name: heat. High-quality LED light therapy devices give off very little heat. Heat lamps simply don’t offer the clinically-proven wavelengths and total power output of a good LED light therapy device.
Is LED flicker an issue?
Short answer: no, not with a high-quality LED light therapy device. But if you go with a bargain option, it might be.
Long answer: LED flicker can be a bad thing. But it largely comes down to these 2 factors:
Cheap LEDs that you can pick up at low prices online may have a significant flicker rate, which can lead to eye strain, fatigue, and other uncool side effects. Stay away.
If you get a cheap light therapy device without verified data and safety, all bets are off. But if you go with a high-quality light therapy product like a INFĒRA, you can trust that the flicker percentages are not just extremely low, but they’ve been tested.
