" Working nights could have a long-term impact on people&amp;#039;s health because it seriously disrupts circadian rhythms, a new study has discovered. Researchers at the Sleep Research Centre in Surrey followed 22 people to see how changing from working typical daytime hours to doing a job at night affected them. Alarmingly, almost all of the participants&amp;#039; genes that were usually programmed to act at certain times were thrown into disarray during the study period. In addition, some of the genes associated with releasing substances vital for the immune system did not get activated at all, meaning employees doing regular night shifts may be vulnerable to illness. &amp;#039;This really explains why we feel so bad during jet lag, or if we have to work irregular shifts,&amp;#039; said Dr Simon Archer, one of the authors of the study, writing in the journal Proceedings of the National Academy of Sciences. Past research has also found links between nocturnal jobs and cancer, weight gain and heart attacks. Read the abstract "^^<http://www.w3.org/2001/XMLSchema#string>
