When Health Confronts With Some Other Needs.
Throughout the world, millions of people work at night without having a lot of official information about it. In a new University of Princeton study, between 7 and 15 percent of the workforce of industrialized countries is involved in some type of night work, despite evidence of its adverse impact on human health.
"The main problem is our internal biological clock, and he is set to the outside world, ie to display darkness and light cycles," says Russell Foster, a sleeping expert and a professor at Oxford University. He explains the mechanisms of action of the biological clock on humans and claims that his neglect activates the stress mechanism. Stress then raises blood sugar levels and blood pressure precisely because the body is preparing to respond to the potential threat "which actually does not exist – because we are just at work," notes Foster.
An elevated level of stress can also lead to cardiovascular disease or metabolic abnormalities such as type 2 diabetes. Stress also makes it difficult for the immune system to work, which is a good foundation for higher colon cancer rates or breast cancer
World Health Organization (WHO) classified night work as a possible cause of cancer. These are the consequences of long-term nature, but the lack of sleep also causes acute ones. The most noticeable is the fatigue, which is why the information is not received correctly, the social signals are mistakenly interpreted and the possibility of empathy is lost. Workers in shifts also suffer from heart problems that are caused by continuous work that is in conflict with biological rhythms.
In addition, as every person who has worked on night shifts knows, it is not easy to remove fingers from unhealthy food afterwards. There are studies that say that carbohydrate consumption ranges from 35 to 40 percent after only 4 to 5 days of reduced nighttime sleep due to increased levels of ghrelin hormones that regulate our hunger
It is he who makes us hungry and encourages sugar consumption and carbohydrates. "Ultimately, this is not too good for line or conditions like type 2 diabetes," Foster added.
In addition to more frequent health examinations, workers who have to work at night should risk having heart disease and metabolic disorders such as diabetes close to hand with some kind of healthy food, first of all fruit
Marco Hafner of the Rand Research Institute says governments they became increasingly aware of this major problem, and so the US Center for Disease Control and Prevention declared a lack of public health epidemic.
There is, therefore, more and more awareness that the lack of public health is a problem.
