LACK OF SLEEP EFFECTS


Researchers in the United States carried out at Brigham and Women's Hospital found a link between the two metabolic disorders such as diabetes and obesity with lack of sleep, why it happened like that?. The human body basically has its own rhythm. Move beyond the time limit, even stayed up late, can disrupt our biological clock. At the chaotic rhythm of the human body or not according to the rhythms of the body so be prepared to experience malfunctions of the body (diabetes and obesity).

Based on research from several respondents observed in the laboratory was less sleep or irregular patterns, not in accordance with the biological clock will increase the risk of diabetes and obesity. The researchers used the approach of epidemiological (disease). However, this study examined the respondents in a controlled laboratory environment over a prolonged period of time by changing the hours of sleep or biological rhythms of the human body in this case the change, impose working hours and simulate situations that can cause jet lag.

In that study the researchers found low levels of insulin, a hormone produced by the pancreas to control blood sugar levels. The low insulin secretion to high blood sugar levels after meals and also respondents in the rest of the time did not eat. And this shows that the restriction of sleep for long periods with impaired circadian cycle had lower metabolic rates when resting, however, during the period of study respondents blood sugar levels were measured and observed by the research team.

BWH neurologist says Orfeu Buxton, who has the condition of prediabetes or diabetes have some symptoms of the condition have a greater risk of developing the disease if they are not able to regulate sleep patterns. Similarly, employees who often gets the night shift at higher risk of developing diabetes compared to employees who worked during the day. '' Employees who are working night and often difficult to sleep during the day. They may experience disruption of circadian cycles when working at night and sleep during the day. The proof, it is clear that adequate sleep is vital to health, and it is best to sleep at night,'' said Buxton as BWH released last week.

The research team whose results were published in the journal Science Translational Medicine is an urgent need for efforts to reduce health risks to employees working on night shift. The study also received attention from experts who reviewed the disease diabetes, one of which Matthew Hobbs, head of diabetes research in Britain. Hobbs considered, the study is interesting because it can stimulate the conditions of extreme sleep deprivation and outsmart the body's biological clock that makes the trial participants should be able to move and sleep on a normal activity.

However, Hobbs reminded that the working conditions on the night shift that re-created in laboratory conditions is different from the actual work late at night. '' It is clear that this is not the same as the real experience of night shift workers that they could sleep under the bright lights. The study also included only 21 people that can not be concluded that this finding is consistent with the real conditions.''
