According to Harvard Medical School scientists, the result u known as circadian misalignment u could lead to increased risks from obesity, diabetes and even heart disease. Circadian misalignment refers to the bodys own natural biological clock which regulates when we want to sleep, eat and wake, reports UK newspaper The Telegraph.
To reach the conclusion, researchers took 10 volunteers and subjected them in a laboratory to the equivalent of working various shift patterns during a 10-day period. The volunteers were monitored for alterations in heart rate and body temperature which all implied a slowing of the metabolic rate. They also showed changes to levels in certain hormones important to feelings of stress and well-being.
The disrupted patterns also caused three patients with no diabetes history to exhibit signs similar to people who are more susceptible to developing the condition. After analysing, the researchers conclude that the combination of these effects may help explain the increased risk of obesity, high blood pressure and diabetes found in shift workers.
