The sleep loss 'breathalyzer': Scientists identify tell-tale eye movements that show when a person's brain is impaired by lack of shut-eye
- Researchers tracked people who were kept awake for as many as 28 hours
- They found 'dramatic impairments' in continuous eye-tracking movements and rapid scanning movements
- Lack of sleep has been linked to health including obesity, causing up to 30% of car crashes
Particular eye movements could betray when your brain is impaired by a lack of sleep, a new study suggests.
Researchers found that eye-tracking movements were significantly impaired from people who didn't get to snooze enough.
Additionally, they found they could differentiate when these movements were impaired from lack of shut-eye compared to impairments from alcohol or a traumatic brain injury.
The team, from the National Aeronautics and Space Administration Center (NASA) Ames Research Center in California, says its findings show a need for a 'measure of neural deficits' from sleep deprivation to prevent workers from committing dangerous accidents.

The National Sleep Foundation recommends that adults get between seven to nine hours of sleep every night.s
