At weekends, we tend to sleep longer to make up for this week's lack of sleep time. But according to Sigrid Veasey, a neuroscientist at the University of Pennsylvania, "sleep debt" can be supplemented by extra sleep may be a myth. Research shows that not enough sleep may lose some brain cells.
Veasey and her team put a group of mice in the lab to form a schedule that resembles a person working as a shift worker. They found that the mouse's brain lost up to 25% of its neurons while being alert and cognitively aware. Both are lower. She explained that when mice lose sleep, their brains create a protein that stimulates and protects neurons. But when sleeplessness becomes a habit, releasing neuronal proteins will stop and the loss will accelerate. Veasey and her team now plan to study whether the brains of deceased shift workers have the same damage and use them to detect whether the human condition is the same.
Ensure adequate sleep and protect your brain.
