Blue light can effectively weaken the superbug MRSA

Antibiotics is a major medical study in the 20th century. It is well known that excessive use of antibiotics can cause bacteria to develop resistance to drugs, which may make us repeatedly infected and life-threatening again. As a common bacteria, Staphylococcus aureus, most of them are harmless, but some strains can cause more problems. Methicillin-resistant Staphylococcus aureus (MRSA) is a particularly troublesome bacterium, which is very dangerous for people with compromised immune systems, which means it may cause serious infections in hospitals and nursing homes. However, due to antibiotic resistance, treatment is becoming more and more difficult.

Blue light can effectively weaken the superbug MRSA

Recently, some researchers have discovered thatblue light can weaken a particularly annoying "super bacteria" and make it again affected by mild fungicides. For example, MRSA can weaken bacteria through "photobleaching", that is, by exposing the bacteria to blue light, the color of the bacteria is fundamentally eliminated. Just as when we bleach things in a washing machine, we use chemicals to remove color. At the same time, because these pigments are part of how bacteria infect the host, this may reduce their ability to cause harm.

Light does not kill MRSA by itself, on the contrary, it reduces its defensive abilities enough for drugs and other molecules to complete it, even though those bacteria usually resist them. In tests conducted on mice with MRSA-infected wounds, the researchers found that a mild bactericide like hydrogen peroxide can effectively destroy bacteria weakened by blue light. This technique is used to treat wounds infected by MRSA. The principle is that it will take the shape of a small box with a light and shine on the wound through a hole. Researchers have found that light is safe on mammalian cells. They stated that "this new tool can treat any surface wounds infected with MRSA. These wounds are usually difficult to treat. The device itself is very small and easy to use. People may be able to carry it with them in the next few years."

Dim light at night is not good for human health

A dimly lit environment can make a person fatter, and it can also cause breast cancer to metastasize. The American Medical Association has proved that dim light at night is extremely harmful to human health. Studies have found that dim lights at night can cause circulatory disturbances, which may increase the probability of breast cancer metastasis to the bones, destroy the melatonin produced during sleep, disrupt the normal work of women's ovaries, and may lead to weight gain. Therefore, avoid prolonged exposure to the light Hunan environment, so as not to affect your health.
