I haven't tried it but I too was intrigued by that thread and added it to my list of things to try. It seems like the risks are relatively minimal.

What NIR light are you considering purchasing?

I've purchased this one: https://www.amazon.com/gp/product/B075F7NV56

I'm awaiting receipt.

I've been putting some thought into how I want to quantify outcomes; sleep, perceived energy levels / fatigue, ability to focus (not sure how to measure this). Nothing else has occurred to me yet.

If you had to measure, what would you choose to keep track of?
