We are globalized and have the habits to put off things late. Be it dinner, or be it office works we all have the tendency to delay and work out before the deadline approaches. Sleepless nights due to over-load of works has become an integral part of our daily technology-bound life. Most often at the cost of bunking sleeps we accomplish tasks at the last moment. We are all well accustomed to this habit since a long time. This habits has serious implications in our health. Sleeping less could result in the ageing faster. In a recent study by the Duke-NUS Graduate Medical School Singapore, it has revealed that brain ages faster for sleeping less. Catch the excerpt below to find out more about this recent study on what the experts say:

The findings were based on a 10-year-long study of 66 older Chinese adults aged 55 years and above. By looking into their structural MRI brain scans, which measure brain volume and neuropsychological assessments, and factoring in the hours of sleep they recorded, the researchers found that those who slept fewer hours showed evidence of faster ventricle enlargement and decline in cognitive performance.

“Our findings relate short sleep to a marker of brain aging,” said Dr June Lo, the lead author and a Duke-NUS Research Fellow.

Past research has shown that faster brain ventricle enlargement is a market for cognitive decline and the development of neurodegenerative diseases such as Alzheimer’s, Duke-NUS said.

“Work done elsewhere suggests that seven hours a day for adults seem to be the sweet spot for optimal performance on computer-based cognitive tests,” said Professor Michael Chee, senior author and Director of the Centre for Cognitive Neuroscience at Duke-NUS.

The School said the findings are relevant given Singapore’s rapidly ageing society, and hopes the study paves the way for future work on sleep loss and its contribution to cognitive decline, including dementia.
