My heated tubing never feels "warm" to my skin.

... therapist. When I get lower back pain or sciatica I have a home program of some gentle Hatha yoga stretches which really help and also use an infrared sauna. I avoid NSAIDS because I already have bad reflux issues.

... impossible for me to turn the device off and on again in the middle of the night. I had an idea. Can you tell me if I should buy a camera with an infrared light that will help me record the number of times I wake up in my sleep? If it's impossible to reach over and turn the machine off and back ...

Can you tell me if I should buy a camera with an infrared light that will help me record the number of times I wake up in my sleep? And how would the camera know if you were awake or asleep?....and even if it would what would that change other than ...

Since they operate by looking through your finger, and comparing the difference in transmission between red and infrared light, it shouldn't matter which way you put the oximeter on your finger. Does the watch oximeter look through the wrist? Not the subject at hand, if you want ...

So Granny- I should get out the infrared space heaters this winter? You would need to check the wavelengths of the light. Near-infrared light is wavelengths from 800 to 2,500 nm. The part of the light you can see (visible light) is not NIR. ...

This particular source has a chart but to be honest, I am not sure if there is an overlap. https://www.herschel-infrared.co.uk/how ... ared-heat/ It would appear that a quality IR heater emits all wavelengths of IR including NIR. But I would want a physicist to verify this before ...

If you find out, let me know, please.
