NEW YORK — Researchers have found that lack of proper sleep can increase the risk of diabetes, a chronic condition.
The researchers explained that past beyond temporary mood disorders and tiredness, lack of sleep can inflict lasting damage on your body.
As per the study appeared in the journal Current Biology, lack of sleep reduces the body’s sensitivity to insulin, impairing the ability to regulate blood sugar and increasing the risk of diabetes.
The findings suggest that lack of sleep causes metabolic stress.
“We found that when people get too little sleep it leaves them awake at a time when their body clock is telling them they should be asleep,” said the study’s lead author Kenneth Wright, professor at University of Colorado Boulder in the US.
“And when they eat something in the morning, it impairs their ability to regulate their blood sugar levels,” Wright noted.
The researchers looked at a small number of healthy men and women in their study.
Half of the participants initially slept for up to five hours a night for five days to simulate a regular work week.
Then they slept for up to nine hours a night for five days. The other half completed the sleep conditions in the opposite order.
Blood tests later showed that those who slept five hours a night had a reduced sensitivity to insulin, which in time could increase the risk of getting diabetes.
But when they slept nine hours a night, oral insulin sensitivity returned to normal. Still, it was not enough time to restore intravenous insulin sensitivity to baseline levels.
Regular bedtime beneficial for heart and metabolic health among older adults
KATHMANDU — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But a new study on sleep patterns has suggested that a regular bedtime and wake time are just as important for heart and metabolic health among older adults too.
Researchers at Duke Health and the Duke Clinical Research Institute, in a study of 1,978 older adults, have found that people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.
The study was published Sept 21 in the journal Scientific Reports.
“From our study, we can’t conclude that sleep irregularity results in health risks, or whether health conditions affect sleep,” said study’s lead author Jessica Lunsford-Avery.
“Perhaps all of these things are impacting each other.”
African-Americans had the most irregular sleep patterns compared to participants who were white, Chinese-American or Hispanic, the data showed.
Still, the data suggest tracking sleep regularity could help identify people at risk of disease, and where health disparities may impact specific groups.
Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.Follow @gorkhapost
