Researchers say that risk of having diabetes and heart disease can be linked in the changes of time a person gets up.

Moderate adjustment on the time of getting up such as when having an early weekly exercise, waking up early for work then having a long sleep during day offs could lead to poor health.

According to them those shift workers are more prone to this kind of unhealthy lifestyle. Change of time a person gets up disrupts the natural body clock or what they call circadian system.

Employees having this kind of shift are more expected to develop disease of the heart and Type 2 diabetes compared to employees having regular daytime shift.

Latest study states, those got up at unusual times particularly for adult were found out to increase added levels of fat in their blood and decrease the levels of a compound that lessens blood sugar levels.

The link of alleged 'social jetlag' in non-shift workers with metabolic illnesses like diabetes was incorporated in an available research in the Journal of Clinical Endocrinology and Metabolism. So, employers should also think about the effect of work on sleep and health.

Dr Patricia Wong, of the University of Pittsburgh in the US, uttered: 'Social jetlag refers to the mismatch between an individual's biological circadian rhythm and their socially-imposed sleep schedules.

'This is the first study to show that even among healthy, working adults who experience a less extreme range of mismatches in their sleep schedule, social jetlag can contribute to metabolic problems.

These can contribute to the development of obesity, diabetes and cardiovascular disease.'

Sleep patterns have been examined in a group of 447 men and women and gave them questionnaire to assess the participants' diet and exercise habits.

Volunteers misaligns sleep schedules on free and work days the most are more likely to have poorer cholesterol profiles, higher fasting insulin levels, bigger waist circumference, higher body-mass index and were more resistant to insulin than those who had less social jetlag.

'We may need to consider as a society how work and social obligations affect our sleep and health. There could be benefits to...workplace education to help employees and families make informed decisions about structuring their schedules, and policies to encourage employers to consider these issues,' Dr. Wong added.
