Ask HN: Is Near Infrared LED light therapy fake science?

[d33lio]

I want to say first that I generally regard devices like Near IR LED "therapy" lights as complete fake science and a trope marketed at stupid rich people and bio-hackers.

However, I borrowed a light from a family member recently and found that using it right when I wake up has immensely benefitted my circadian rhythm and I also seem to have more energy without taking stimulants. I've looked up some of the "science" behind these devices [0], even read through a number of the readily available controlled studies that assert a plethora of health benefits from these devices.

Personally, I'm relatively convinced the positive effects I'm seeing are completely placebo or just because I'm sitting in front of a warming bright light for ten minutes each morning.

What are your thoughts?

You can match the light wavelength and wattage for well under $100. Their has some designed in light blocking patterns that make it look expensive, but have a low cost. They also mention class II medical device. Look here for what that entails, might cost a little to get the approval, a few bucks per light? https://www.fda.gov/medical-devices/overview-device-regulati...

I’m not sure about near-infrared specifically, but I’m certain that shining light on yourself at “good” wavelengths can be beneficial. Specifically the use of a 10000 lux led panel to mimic the sun in the morning definitely helps with seasonal affective disorder on gloomy days.

The logic behind IR light is entirely plausible too. Light is energy, it’s not like photosynthesis is the only way an organism can leverage light.
