What do you think, should the people work at night? Even if we all want to imagine a world where sleep everything, is quite difficult. There are a huge number of important public institutions and services, whose work must not be interrupted 24 hours a day. Imagine that night you became ill, but the ambulance call is impossible, as doctors lay down to sleep. Absurd, isn’t it? Nevertheless, experts advocate the limitation of this kind of work to the maximum. The reason is that working at night has a negative effect on the operation of the circadian (biological) rhythms.
Circadian rhythms are biological rhythms of an organism with a period of about 24 hours, which every day is followed by all living beings on Earth. Millions of years of evolution was the reason that circadian rhythms are responsible not only for the sleep and wakefulness of living organisms, but many other factors such as body temperature, metabolism, hormone levels, etc.
Recall that in 2017 the Nobel prize in physiology or medicine was awarded for the study of the mechanism of circadian rhythms. The work of three researchers who shared the award, confirmed the theory that all living organisms follow its own internal biological clock, and therefore, fall asleep, Wake up, eat Breakfast and work at different times of the day. It is not surprising that irregular working hours have a negative impact on health, relationships, and social ties of so many people. However, the greatest harm is caused by the neglect of sleep. And it absolutely can not do, if you want to live a long and healthy life.
Than a dangerous job at night?
In 2019, the International Agency for research on cancer (IARC) has prepared a report on food safety, environment and labor, where was offered a number of recommendations about how to work in the night time. So, the report States that night work is directly related to sleep disorders and metabolic disorders, due to which people suffer from excess weight and diseases like type II diabetes, and probably cardiovascular and mental illnesses. The study notes that such work, coupled with a lack of sleep increases the risk of developing breast cancer in women.
Also, realizing that in some cases, night work is inevitable, researchers are advised to strengthen medical monitoring of employees who are forced to abide by long hours of labor. Among jobs that are associated with the risk of developing many diseases because of night work, are drivers of vehicles, soldiers, police and medical personnel.
Why not neglect sleep?
In 2014, scientists from the research center of the Surrey sleep (SSRC) in the UK foundthat working at night affects the body at a molecular level. The study covered a small group of people and changed their usual mode of sleeping and waking for work at night. A blood test subjects showed that about 6% of the genes designed for more or less active at certain times of the day. After subjects switched to night work, this genetic accuracy fell to 1%. By the way, surely you will be interested to know that during sleep, cerebrospinal fluid in the truest sense of the word washes the brain.

Moreover, lack of sleep can lead to difficulties in concentration. Thus, the results of a studythat analyzed multiple injuries received in the workplace in the period from 1996 to 2006, showed that those who work nights have a higher risk of injury. Also lack of sleep can cause the development of depression. This is evidenced by the results of a study published in the journal of the National Center for Biotechnology Information, where is the evidence that working nights increases the risk of depression. So please, get enough sleep and follow the regime of work and rest.
