( — April 16, 2021) Orlando, FL — Various research studies have been carried out to look into the negative impacts of poor sleep. It is worth keeping in mind that it has long been associated with a myriad of undesirable health consequences. 

A study was carried out and published in the Acta Diabetologica journal.

In this research, it has been found that individuals with prediabetes and diabetes with lower sleep efficiency have poorer cognitive function compared to those with better sleep efficiency. It is worth noting that sleep efficiency pertains to a measure of how much time in bed is actually spent sleeping.

According to Dr. Sirimon Reutrakul, the cognitive effects of poor sleep quality are worse for this population, which we know is already at risk for developing cognitive impairment as a result of having diabetes. 

Reutrakul is associate professor of endocrinology, diabetes and metabolism in the University of Illinois at Chicago College of Medicine and corresponding author on the paper.

Previous research studies have shown a link in between diabetes and cognitive impairment as well as an increased odds of dementia. There have also been other studies showing the association in between sleep disturbances and cognitive impairment. 

It is worth realizing that sleep disturbances are common in individuals with diabetes.

In this research, the investigators looked into the link in between sleep and cognitive function in those with abnormal glucose tolerance. This refers to patients suffering from an impairment in glucose tolerance indicative of prediabetes, as well as those with clinically diagnosed diabetes.

It involved a total of 162 subjects, 81 of whom were with Type 2 diabetes and 81 with prediabetes. Further, the average age of the participants was 54.8 years. The investigators looked into the sleep duration and sleep efficiency of every participant through seven-day actigraphy recordings.

“Our study shows that lower sleep efficiency is independently associated with lower cognitive function in patients with abnormal glucose tolerance,” said Reutrakul. “Further studies should look at whether helping these patients sleep better could improve cognitive function.”

Sleep and cognitive health issues are undeniably prevalent today. It is also worth realizing that more and more researchers are studying on some remedies that could be extremely helpful in enhancing sleep quality and quantity as well as cognitive performance. 

These include the use of certain nutrients, such as B vitamins. These can be obtained through the use of formulas like Divine Bounty B Vitamin Complex.

It contains Choline, Pantothenic acid, Biotin, Vitamin B12, Folic Acid, Niacin, Riboflavin, Thiamin, and vitamin B6 (
