Blue Light is vital on disinfecting surfaces and water!

Blue light is a type of light that has a wavelength of about 480 nanometers, which is shorter than other colors on the visible spectrum. This shorter wavelength means that blue light has more energy and can penetrate deeper into the skin and other tissues. While blue light is often associated with electronic devices and is known to disrupt our sleep patterns, it has several benefits that are worth exploring.


One of the most significant benefits of blue light is its ability to kill bacteria. Blue light has a unique property that allows it to activate porphyrins, which are molecules found in bacteria. When blue light is absorbed by porphyrins, it produces singlet oxygen, a type of oxygen that damages the bacterial cell membrane and kills the bacteria.


This property of blue light has various medical and therapeutic applications. For example, blue light therapy is a type of treatment that uses blue light to kill the bacteria that cause acne and reduce inflammation. The blue light penetrates the skin and activates the porphyrins in the acne bacteria, which then produces singlet oxygen that kills the bacteria.


Moreover, blue light has been used to disinfect surfaces and water. In healthcare settings, blue light is effective in killing various types of bacteria, including MRSA and E. coli. In water treatment plants, blue light has been used to kill harmful microorganisms and disinfect water.




Additionally, blue light has the potential to inhibit the growth of certain types of bacteria that can cause food spoilage. This could lead to longer shelf lives for food products and reduce food waste.


Overall, while blue light can disrupt our sleep patterns, its benefits in killing bacteria are promising. Researchers are still exploring the various applications of blue light, but its potential in medicine, therapy, disinfection, and food preservation is exciting and could have a significant impact on our health and well-being.
