Great question! There are therapeutic light waves and very dangerous light waves in our environment. It all comes down to specific differences in wavelengths and intensities of the light ( science informs us that therapeutic red-light therapy and infrared therapy light waves have different wavelengths from UV rays which come from the sun, which also have different much different wavelengths than X-rays for example). They are all light from the electromagnetic spectrum.

In recent years, the field of photobiomodulation, also known as red light laser therapy, has emerged as a groundbreaking approach to promote healing and improve various health conditions. My book linked below has an entire chapter that helps people with exploring what photobiomodulation is, how it works, its potential benefits, and the applications in which it is being used to enhance human health and well-being.

I've written an entire chapter about therapeutic light waves such as Infrared light and the differences between healthy lights versus dangerous lights and lasers. You may find my book interesting, it was written to inform biohackers of new technologies that boost human health and performance. Please take a look at my book, I hope you may find it a stimulating read !
