Understanding the therapeutic value of light.
What is light? Electromagnetic radiation that is between 380 and 750 nm.
I am often asked about the therapeutic value of red light, lasers and sunshine itself. Sunlight has a spectrum of short to long wavelengths. The long wavelengths are the best for you. They are more in the red spectrum.
I personally stopped wearing sunglasses 2 years ago when I came across a study demonstrating that certain wavelengths of sunlight are beneficial globally for the body. Since that time much more about long wavelength light has been shown.
1. Blood sugar modulation. Long wavelength light pe*****tes the entire body, through your clothing, stimulating numerous cells mitochondria. The energy center of your cells. Regulating glucose.
2. Collagen production to decrease wrinkles
3. Reduce inflammation and as such pain.
4. Speed the healing of the skin.
5. Production of vitamin D. Globally beneficial for hundreds of reactions in the body.
6. Immune system stimulation.
7. Global eye health.
8. Improvements in menstrual cycle
What about the devices? The good the bad and the ugly.
1. Red light therapy. There are lasers that are strong and if using them you will be in need of eye protection. These can be very expensive and best used by professionals. Secondly there are red light devices that are less strong yet very effective. You will need red light, 670 nanometers and up, to get the benefits, if using a red light device. Do some research. These devices are often used for 3-5 minutes 2x per week at 6 inches away from face. See my personal favorite, Lumebox, a hand held red light home therapy device.
2. Your phone and computer screen are light emitting devices. They put out mainly blue light. Blue light is shorter in wavelengths and doesnβt pe*****te the body very far. It can be used for some skin conditions however. Yet the blue light emitted from your devices and LED light bulbs is often excessive in amount and is bad for mitochondria. Negatively affecting your energy levels.
Note that the sun is the ultimate device when dosed properly. Cloudy days you will still get some long wavelengths. Which will pe*****te clothing! It is still worth it to get outside.
Smarter bulbs? Halogen incandescent lights are old school light bulbs. They are much healthier and can still be purchased.
Hack! Looking at trees bounces long wavelength light to your eyes is very healthy for you entire body and especially your eyes.
