A study from the American Journal of Respiratory and Critical Care Medicine showed that by observing the lungs of volunteers who had used household chemical cleaning products, it was found that the lungs of people who used chemical cleaning products on a regular basis were comparable to those who smoked daily for 10 to 20 years. People who smoke a whole pack of cigarettes have the same lung injury status. Some detergents contain protease, which can decompose human protein and damage the skin after washing with hands directly in contact with washing powder, soap, etc. What's more, it will affect the immune function of the human body and lead to the occurrence of cancer.
Among the hazards of detergents is a substance called nonylphenol (NP), which can cause neurotoxicity in the body and lead to learning and memory impairment when exposed to the air. As the research progresses, more and more evidences show that exposure to NP environment can seriously affect human adaptation to changing society.
Recently, the journal "Food Chem Toxicol" published the latest research from the research team of Professor Huang Huiying from South China Agricultural University. The research shows that Nicotinamide Mononucleotide (NMN) has a therapeutic effect on neurodegenerative diseases.
The researchers measured memory-related receptors (serotonin receptors) in the hippocampus, an area of the brain associated with learning and memory, and found that NP exposure significantly reduced serotonin receptor levels. On this basis, South China The Agricultural University team stated in the paper that nicotinamide mononucleotide (NMN) can not only pass through the central 5-HT system, but also improve NP-induced learning and memory impairment in rats through the NAD/SIRT1/MAO-A pathway.
