Most people associate cortisol with the “fight or flight” response. While this biochemical indeed functions as a stress hormone—and can have negative effects in excess—it is a necessary hormone for a variety of human biological functions. It is produced from cholesterol in the adrenal glands, which sit directly on top of the kidneys. It is released […]
Biological Rhythms Are Present Throughout Nature
When researchers talk about biological rhythms, most people assume they are talking about the internal clocks of animals. However, internal clocks are not limited to just mammals. Have you ever wondered if plants sleep? While this may seem like a philosophical question, researchers in chronobiology may have found the answer. Although modern chronobiology research focuses […]
Disrupting the Circadian Rhythm of Cancer: Potential for New Treatment
Understanding and attacking the circadian rhythm of cancer cells may be the most effective way to treat cancers such as acute myeloid leukemia, according to a new study. Treating cancers such as acute myeloid leukemia is one of the greatest challenges in modern medicine. Because cancer cells are human cells, many therapies that target cancer […]
Discovered: How Temperature Shifts the Circadian Clock
Do you get sleepy when you are cold? Researchers have discovered new insights about how temperature affects the circadian rhythm. The circadian rhythm is a 24-hour cycle that determines when we sleep, when we wake and when our body performs important cell repair processes. This internal clock is set by external cues such as light […]
An Intricate Web: The Circadian Rhythm, Sleep Disruptions and Epilepsy
A new study finds that there is a link between sleep disruptions and epilepsy, suggesting that the circadian rhythm affects seizure disorders. Epilepsy is a disorder of the electrical wiring of the brain in which affected people suffer from seizures, which are temporary losses of consciousness caused by abnormal electrical activity in the brain. 125,000 Americans […]
