Losing Just Half An Hour Of Sleep ‘Can Impact Body Weight And Metabolism’


In the annual meeting of the Endocrine Society in San Diego, CA the findings of the new research at ENDO 2015, suggested that losing half an hour of sleep can have the long term consequences such as obesity problems and metabolism effects. So, for this study researcher from Weill Cornell Medical College in Doha, Qatar, they have recruited almost 500 plus members who are suffering from type 2 diabetes.

So initially the study, the researchers took the measures of their body’s height, weight and they took the blood samples to measure the insulin sensitivity. Also, the participants had to maintain the sleep diary were the weekdays “sleep debt” can be calculated.

At the start of this study it was found that the participants who have weekday sleep debt they are 72% more obese when compared with the participants who had no sleep debts. After following up for 6 months, the relation between the obesity and the sleep debt was clearly visible and it had significant impact.

After following the same study for 12 months, the researchers observed and stated that the participants who had 30 minutes of weekday sleep debt they are 17% more obese and 39% increment in risk of insulin resistance. So, it was clearly observed and proved that the people who have 30 minutes of sleep debt will have obesity problem and less insulin resistance. Also, they affect the metabolism functions too.

People try to compensate their sleep during weekends

People often accumulate their sleep debt during weekdays and complete them during the weekends. But, Prof. Shahrad Taheri explained that the sleep loss is additive and it have the huge impact on metabolism functions.

Researchers from University of Chicago, MI, also published their results of their study in the journal Diabetologia regarding the relation between the diabetes and sleep loss. The researchers have found and clearly explained that after 3 nights of getting 4 hours sleep, blood levels of fatty acids remain elevated, where they peak and recede normally. Also, the elevated levels of fatty acids reduce the ability of insulin to control blood sugars during 4 am to 9 am.

Also, in the month of December 2014, Medical News Today reported on the study published in the journal “The Journal of Pediatrics” that found chronic problems while the people have lack of sleep and sleep related breathing problems which doubles the risk of child being obese at the age of 15.

Prof. Karen Bonuck from Einstein college of Medicine of Yeshiva University in New York commented “If impaired sleep in childhood is conclusively shown to cause future obesity, it may be vital for parents and physicians to identify sleep problems early, so that corrective action can be taken and obesity prevented. With childhood obesity hovering at 17% in the US, we’re hopeful that efforts to address both of these risk factors could have a tremendous public health impact.”
