Light therapy heals with photons. A red incandescent bulb throws more heat than light, so it’s not likely to have a light therapy effect. Yes, you can use light therapy to reduce acne scars. Traumatic brain injury, Parkinson’s and dementia respond to red and infrared light therapy.
What is a “Dose” of Red Light Therapy?

What is a “Dose” of Red Light Therapy?

A dose of red light therapy is a quantity of energy measured in joules from light with a wavelength of 600 to 1200 nanometers. Whether the dose we just defined is actually helpful to the body depends on the wavelength being the right one for the target treatment, and the energy quantity being sufficient to kick off energy-creation and healing cascades of events.

Best Bulb Red Lights

Best Bulb Red Lights

Therapy bulbs pack a lot of power into a small device. You mount the bulb into a light socket either as a handheld or on a lamp. I buy adjustable lamps for my bulbs or just hold them using a corded socket and switch.
Best Panel Red Lights

Best Panel Red Lights

Panels are tall units that you hang from the wall or ceilinig (if you do hang it from the ceiling, don’t sleep under it, just in case it isn’t properly fastened). Panels treat large areas of the body and so are good wellness devices. Panels usually run on household electricity, so they are not guarded from emitting non natural EMFs. Allow 6 or more inches between you and the therapy device that runs on household electricity. Panels are best for people who want to absorb light on the widest area in the shortest time.
Best Pad Red Lights

Light therapy pads have a huge advantage over other device designs. You can wrap a pad around the treatment spot for a hands-free session. So long as the pad is battery-operated, you have portability and mobility too.
Best Handheld Panel Red Lights

Best Handheld Panel Red Lights

A handheld light therapy device is small enough to hold in one hand. You use it to target specific areas without  affecting anything else. You can reach anywhere with a handheld, with the possible exception of the middle of the back. To move about while using a handheld, get a battery-operated variety.

Evidence-Based EMF Therapy and Protection

The color blue, a radio wave, and an x-ray beam are each fields of light particles that travel in waves. Also known as “electromagnetic fields” (EMFs), these waves of energy range from weak to powerful. Long waves have relatively little energy per photon. Short waves can knock the electrons right out of your DNA.

Only a tiny part of the spectrum includes the light that we as humans can actually see: violet, blue, green, yellow, orange and red. EMFs can be healthy or harmful. Ultraviolet and blue light are both. Ultraviolet helps us create Vitamin D, and it causes sunburns and skin cancer. Blue light can kill P acnes bacteria, which clears the face, but it can also hurt the eyes.

Red light is a healing EMF because it creates a cascade of energy starting at the mitochondria. This is why red light therapy works for so many problems. EMF Channel explores all the ways the EMFs can help us heal, and how to protect ourselves from the ones that do us harm.
