Sleeping More Than Ever Before: The Surprising Science of Extra Sleep and Anxiety

For centuries, sleep has remained one of humanity’s greatest biological mysteries. We spend roughly a third of our lives doing it, yet scientists are still trying to fully understand why the brain insists upon sleep. It seems clear that sleep restores the body, sharpens memory, regulates emotions, and keeps countless internal systems in balance. But one major problem has always complicated sleep research: most experiments focus on what happens when sleep is taken away. That approach has taught researchers a great deal. Sleep deprivation has been linked to poor concentration, weakened immune function, emotional instability, and a long list of health problems. Yet asking what happens when sleep is removed only tells part of the story. It is a little like studying hunger by starving people without ever exploring what happens when they are exceptionally well fed.
