A recent study, by the World Health Organization (WHO), revealed the fact that working in night shifts may cause serious problems including an enhanced risk of cancer in humans. Women are at specific risk in such an environment of working in the night shifts.

The study findings bring out the fact that after a prolonged exposure to the night shifts women have higher risks of developing breast and colon cancer. Men are equally at risk with the night shift working conditions. Men have more probability to suffer from the prostate cancer.

Night Shift

Almost 15 to 20% of the working class population in the United States and the Europe is undergoing a night shift working schedule. Such night shifts working system is very much prevalent in some specific business sectors including healthcare, transportation, communication, leisure, and hospitality industries.

“Shift work that interferes with regular nighttime sleep disrupts
Circadian rhythms, our body’s natural clock,” said Dr.Erhards Haus of HealthPartners Research Foundation. Dr.Haus was associated with this study of the World Health Organization (WHO) and was also the Chairman of a working sub-group of this study.

In all 24 scientists from 24 countries representing this global research were parts of this study. This group of scientists carried out an intensive assessment of the potential carcinogenicity of the shift work, painting, and firefighting.

This group of scientists also performed an extended analysis of the several epidemiological studies conducted earlier including the experiments performed on various animals and determined overall impacts on the human bodies.

This intensive study established the fact that an occupational exposure as a painter is extremely carcinogenic to humans. Similarly, the study also concluded classifying the occupational exposure as a firefighter is also equally carcinogenic to humans.

The study findings explain the impacts and effects on human body and say, “This impedes biologic function by suppressing the immune system, reducing melatonin production and may damage genes leading to the production of abnormal cells.”

A preliminary report of the ‘Agency for Research on Cancer (IARC) ‘ is set to be published in the Journal “Lancet Oncology” on December 7, 2007.IARC is an agency of the ‘World Health organization(WHO)’.
