Let’s clear this up because it keeps getting butchered online.
Red light DOES NOT increase melatonin production.
That’s influencer bro science… not actual science.
(They do that a lot...)
What red light does, when it’s the right wavelength and not blindingly bright,
is not crash melatonin the way white or blue light does.
And that distinction matters more than people realize.
It does not produce it...it just preserves what you have...
Your circadian rhythm is incredibly sensitive to light exposure at night.
Flip on a bright bathroom light at 2am and you’ve basically told your brain it’s morning...
Melatonin drops.
Sleep pressure + momentum disappears.
Good luck falling back asleep.
Red light helps us avoid that problem.
It gives you just enough vision to navigate…
without slamming the brakes on melatonin release.
That’s why it’s such a smart ambient lighting option.
New parents.
People who get up to p*e at night.
Anyone trying to protect their sleep quality without living in the dark.
Motion-sensored red night lights are one of the simplest, highest ROI sleep upgrades you can make.
Not supplements.
Not gadgets strapped to your face.
Just smarter light exposure.
Sleep isn’t fragile because you’re broken.
It’s fragile because the environment matters more than most people think.
And yes… i brought receipts...
