This is the red light device I use for drug free, nasal allergy symptom relief (no affiliation).

You can find it on Amazon, and it only costs around US$20.

I use it for 5 minutes nightly before bed.

My conventional allergist was amazed at how well this controls inflammation.

While not a root cause solution,

its a great alternative to steroids and anti-histamines until the immune system is tamed.

The science of light (and all the mistakes weve been making with it) is going to be exploding in the next 10-20 years...

Light and EMFs are going to be the "cigarettes" of our generation.

This is not a laser (even though its marketed as such).

No comparison to the vie light-only for allergy relief; doubt it impacts brain function.

But great deal for the price!
