I have seen a bunch of new centers open that generously use blue lighting for aesthetics. Given what we know about blue light and its suppression of the release of melatonin, a natural relaxant, do you think the blue light is interfering with the persons ability to relax while floating? I guess a counter-argument could be made that during the hours that the sun is out, we are receiving blue light anyways, but I am curious to hear others' opinions on this.

We did LED uplighting in our float room, so its not direct and reflects off the walls and ceiling. I never really thought about the effects of the blue light. I just thought of it as more of "mood lighting". We keep the intensity of the light low and usually on a purple or blue color. I feel those colors make people feel more relaxed before their float, and they are only exposed to it for a few minutes for their before/after shower. Just the other day we had a client float with the lights on (we have a glass door for our cabin) and she loved the lights. She said it helped her stay relaxed and calm so she left them on. We also have the ability to change the color of the lights from outside the room. We let clients know their time is up by turning the lights on, and we change the color to a yellow/orange color to help "wake" them up.

yeah, I do like the perspective that our perception dictates a lot, so even if there is a physical influence (not saying it is disruptive), if our perception of it relaxes us, that is more powerful.

From what I understand, blue light isn't an issue unless you're taking in a lot during the night time hours as it suppresses melatonin. And unless the lighting design in the float center is REALLY bad the blue light should be indirect and softened as it reflects off of walls and surfaces first. The real harm comes from blue light fired straight into your eyes from sources like a smartphones or computer screens. That being said, a dimmer for your light system is a great, cheap way to control the amount of light exposed to your clients. Stay away from colored lights (especially LEDs) unless for small accents and use a more natural, broad spectrum lamp for the overall lighting design.

There are LED options that limit the blue light, if you'd still like to use LED for the lower electrical impact. ;)

I would say it absolutely does.


Here's a quick experiment you can try on yourself:


Download f.luxand sit in a room without dirrect sunlight. (You probably don't have, or want to have, sunlight beating in on your center.) Spend about 20-30 minutes with f.lux settings turned all the way up, meaning the blue light output turned all the way down. Then, turn f.lux off. You will eperience a sharp "shock" to not only your eyes, but your system. It can be very jarring. I would go further to add that the blue lights are probably having a considerable negative effect on the people on their way out, more than the people on their way in. There are special LED's that provide low blue light and I would highly recomend their use in float centers. I get the astetic desires for the blue lights, but with all of the "light therapy" that gets discussed in and around floatation we should really be more attentive to our blue light exposure and that of floaters who just came in to relax.

I have a red filter on both my phone and laptop, and it really does wonders helping me fall asleep. The LEDs are a great idea.
