Lack of Proper Sleep May Lead To Impairment of Mental Skills: Study

Even a single night's sleep can affect a person's ability to think.

While lack of proper sleep has been known to affect health, a new study has showed that people who sleep less or more than an average of seven to eight hours per night are more likely to develop impairment in their mental skills.

The findings showed that this effected adults equally.

The amount of sleep associated with highly functional cognitive behaviour was the same for everyone (seven to eight hours), regardless of age.

Also, the impairment associated with too little or too much sleep did not depend on the age of the participants, the researchers said.

“We found that the optimum amount of sleep to keep your brain performing its best is seven to eight hours every night and that corresponds to what the doctors will tell you need to keep your body in tip-top shape, as well,” said lead author Conor Wild, Research Associate at the University of Western Ontario in Canada.

“We also found that people that slept more than that amount were equally impaired as those who slept too little,” Wild added.

For the study, published in the journal SLEEP, the team examined more than 40,000 participants.

Nearly half of all participants reported typically sleeping less than 6.3 hours per night, about an hour less than the study’s recommended amount.

Most participants who slept four hours or less performed as if they were almost nine years older.

Importantly, the participants’ reasoning and verbal abilities were two of the actions most strongly affected by sleep while short-term memory performance was relatively unaffected.

On the other hand, even a single night’s sleep can affect a person’s ability to think. Participants who slept more than usual the night before participating in the study performed better than those who slept their usual amount or less, the researchers said. (IANS)

"Our study suggests that many of the genes important for sleep in animal models may also influence sleep in humans and opens the door to better understanding of the function and regulation of sleep," Dashti added.

Experiencing problems like insomnia or hypersomnia could be genetic, say researchers who identified 76 new gene regions associated with the time a person sleeps.

It is well known that regularly getting adequate sleep — 7 to 8 hours per night — is important for health, and both insufficient sleep — 6 or fewer hours — and excessive sleep — 9 hours or more — have been linked to significant health problems.

Family studies have suggested that 10 to 40 per cent of variation in sleep duration may be inherited, and previous genetic studies have associated variants in two gene regions with the sleep duration.

The study from the Massachusetts General Hospital (MGH) in Boston, US, analysed genetic data from more than 446,000 participants, who self-reported the amount of sleep they typically received.

The study identified 78 gene regions — including the two previously identified — as associated with sleep duration.

While carrying a single gene variant influenced the average amount of sleep by only a minute, participants carrying the largest number of duration-increasing variants reported an average of 22 more minutes of sleep, compared with those with the fewest.

This was comparable to other well-recognised factors that influenced sleep duration.

“While we spend about a third of our life asleep, we have little knowledge of the specific genes and pathways that regulate the amount of sleep people get,” said Hassan Saeed Dashti from MGH.

“Our study suggests that many of the genes important for sleep in animal models may also influence sleep in humans and opens the door to better understanding of the function and regulation of sleep,” Dashti added.

The study, published in Nature Communications journal, also found shared genetic links between both short and long sleep duration.

It also found factors such as higher levels of body fat, depression symptoms and fewer years of schooling, implying negative effects from both too little and too much sleep.

While short sleep duration was genetically linked with insomnia and smoking, long sleep duration was linked with ailments such as schizophrenia, Type-2 diabetes and coronary artery disease. (IANS)
