I'm going to be sticking a light up my nose once a day for the next 3 months.
It's called intranasal photobiomodulation. Four applicators, 25 minutes a session, and you look completely deranged using it.
The premise: the nasal cavity is the shortest route to the underside of the brain, and it's packed with capillaries. So instead of shining light on your skin and hoping, you go in through the nose.
What
@VielightInc says each wavelength does:
→ 810nm near-infrared — cognitive function. 10Hz for relaxation, 40Hz for focus
→ 633nm red LED — systemic wellness and immunity
→ 655nm red laser — same, different delivery
→ 470nm blue laser — intranasal microbial sanitisation
They have 30+ published and ongoing studies. I haven't read them all yet.
But here's what I find odd.
Red light therapy on your body? Everyone's on it. Sunlight, circadian rhythm, methylene blue, all heavily covered on X.
Intranasal? Almost nothing.
Either it doesn't work, or it works and nobody's looked. I don't know which yet.
So I'll do what I always do. One variable, three months, and I don't judge it before then.
I'll report back either way, including if it does nothing.
