Plant lectins are being studied for over a century. Until a decade ago, most information was obtained from biochemical, molecular, and structural studies of a reasonably high but still limited number of abundant lectins from seeds and vegetative storage organs.
Light therapy boxes should be designed to filter out harmful ultraviolet (UV) light, but some may not filter it all out. UV light can cause skin and eye damage. Look for a light therapy box that emits as little UV light as possible. If you have concerns about light therapy and your skin, talk to your dermatologist.
Infrared has a longer wavelength than visible light. Infrared is close to red colour in visible spectrum and hence it is sort of redder-than-red light or beyond red light, that is why the name infrared. Infrared radiation cannot be seen but can only be feel as a heat.
