In a recently published study, the University of Helsinki, the Finnish Institute for Health and Welfare, the Finnish Institute of Occupational Health and the Finnair airline investigated dynamic changes to DNA methylation in shift workers. DNA methylation denotes epigenetic regulation that modifies gene function and regulates gene activity without changing the sequence of bases in the DNA.
Short-term genetic changes caused by DNA methylation are not well known. While methylation is connected with our surroundings, more research is needed on how
