Even though sleep gives your body the rest it needs,your mind is still hard at work. It’s actually processing and consolidating your memories from the day. If you don’t get enough sleep, who knows where those memories go. Or worse, your mind might actually create false memories.
The bottom line: Sleep is good. And necessary.Roy Kohler, MD, who specializes in sleep medicine at SCL Health in Montana, reaffirms all we know about the benefits of sleep, citing research that shows people who get less sleep tend to be heavier, eat more, have a higher BMI, and are more likely to be diabetic. “Consistent sleep of seven hours a night is what’s recommend for adults just for daytime functioning—being on task, being alert for the day and being able to concentrate and not be so moody and tired during the day,” says Dr. Kohler.
