If you are anything like me, you use the late-night hours to get things done. Indeed, most of us give up sleep (either late at night or early in the morning) to log on our computers and zip off e-mails or finish tasks. So, this new survey is a bit scary. The study, conducted by Princeton University, found that sleep deprivation can affect brain cells and take a toll on your memory and your thinking. No wonder I can't remember an appointment unless I write it on my calendar.
The Princeton study was conducted on rats. It found the stress of sleep deprivation after three days may include a temporary drop in the brain's production of new nerve cells and an increase in stress hormones. The good news is the effect disappeared after three weeks. Not much comfort though for those of us who continue to use late night or early morning to get things done.
