Why are some people full of energy first thing in the morning, while others don’t really come into their own until the evening? The answer lies, in part, in our internal clock. It influences when we get tired, when we wake up, when our body temperature rises, and at what times of day we are […]Why are some people full of energy first thing in the morning, while others don’t really come into their own until the evening?

When the Brain Dreams, its Energy Balance is Thrown off
During REM sleep, the brain exhibits an unusual combination of phenomena: Blood flow increases, and levels of an important metabolic component also rise—while at the same time, ATP levels—the brain’s primary energy source—decrease in nerve cells. Researchers at Tohoku University have studied this relationship in sleeping mice in real time. The results show that the […]During REM sleep, the brain exhibits an unusual combination of phenomena: Blood flow increases, and levels of an important metabolic component also rise—while at the same time, ATP levels—the brain’s primary energy source—decrease in nerve cells.

Body Clock and Stroke: How the Circadian Rhythm Might Affect Brain Recovery
After a stroke, the brain begins a lengthy repair process. This process involves more than just replacing damaged nerve cells or establishing new connections; metabolic byproducts and inflammatory signaling molecules must also be removed from the affected tissue. A new study from the University of Rochester now suggests that the body’s internal clock may play […]After a stroke, the brain begins a lengthy repair process.

Sleep Is More Than Just the Number on the Clock: What REM Sleep, Deep Sleep, and Sleep Patterns Reveal About Our Health
How much sleep we get has long been considered an important factor in our health. But a night’s sleep isn’t simply a matter of a certain number of hours. While we sleep, our brains go through various sleep stages that alternate several times throughout the night. A large new study now shows that this sleep […]How much sleep we get has long been considered an important factor in our health.

What Our Daily Rhythms Reveal About Biological Aging
Our bodies follow a daily rhythm. Activity and rest alternate; we become more active at certain times of the day and return to a state of rest at other times. This pattern is not random. It is linked to our biological clock and the timing of numerous bodily functions. But could our personal daily rhythm […]Our bodies follow a daily rhythm.
