Work when people sleep at night and sleep when people work can pose a risk of various diseases if done continuously. Working at night can disrupt circadian rhythm or biological processes of the human body for 24 hours.
Medical director of the sleep laboratory University of Kentucky, Barbara Phillips said, it makes the quality of your sleep for the worse. This condition causes the secretion of various hormones in the body.
"Night shift workers have consistently experienced less sleep 1-3 hours within 24 hours compared to non-shift worker. They may be more fragmented sleep and low quality," said Phillips.
Phillips explained, working at night or sleep deprivation will lead to the risk of various health problems.
"Night shift workers have an increased risk of obesity, prostate cancer for men, breast cancer in women, ulcers, complications of pregnancy, diabetes and heart disease," he said.
A 2012 study published in the journal Occupational and Environmental Medicine also showed that night work may increase the risk of cancer by 40 percent in women. The survey was conducted on 18,500 Danish women who worked night night in 1964 and 1999.
Associated risk of diabetes, a study in 2013 which was also published in the journal Occupational and Environmental Medicine found that night work may increase the risk of diabetes by 9 percent. This risk is primarily due to poor diet and metabolic changes in the body due to working at night.
Phillips said, sleep at night can reduce the production of the hormone melatonin or sleeping. In fact, this hormone is considered to prevent cancer.
Meanwhile, an assistant professor of psychology and behavioral sciences Argosy University in Arlington, Virginia, Stephanie Dailey said, working at night not only affects physical health, but also mental and emotional person. According to him, someone who works at night is easier to feel uneasy and decreased cognitive abilities.
"You decreased ability to pay attention, this is a problem for a lot of jobs that require precision. Cognitive ability was decreased thus hindering your work," said Dailey.
Dailey said, those who work the night shift are also known to have higher levels of stress. They are prone to anxiety and depression.
To create a good quality sleep, Dailey advise someone to sleep and wake up at the same time each day. Avoid working the night shift in a long enough period of time.
