New research showed that the internal circadian clock is influenced not by the brain only, as previously thought, but by the liver as well. Collaboration between scientists from the University of Queensland’s Institute for Molecular Bioscience in Australia and Université Paris Cité/CNRS in France has discovered that by transplanting human liver cells in mice, the circadian…

“Early to bed, early to rise” has been well-regarded health advice since ancient times. An ancient Chinese saying says, “Work since sunrise and rest at sunset.” But why is sleep so important? The idea of activity beginning at sunrise and ending at sunset aligns with the laws of nature and the human body’s internal processes….

With screen usage skyrocketing, scientists and eye care professionals have discovered that the secret to strengthening and maintaining the health of your visual system is getting sunlight exposure early in the day.

The spread of cancer cells follows a distinct time pattern. At what time of day do cancer cells spread the fastest? Scientists have found the answer: It is when people are sound asleep at night. A Major Culprit of Cancer Metastasis Over the past decade, cancer metastasis has been a major focus of clinical cancer…

Cancer cells can appear anywhere in our bodies at any time. Fortunately, they are almost always recognized and eliminated by our immune system. Immunotherapy is a type of cancer treatment that can help the immune system fight cancer. Scientists have discovered that the effectiveness of immunotherapy is influenced by circadian rhythms; performing it at the…

Getting outside during the day, even when it’s cloudy, may benefit your sleep, research with college students suggests. As reported in the Journal of Pineal Research, the study finds that University of Washington students fell asleep later in the evening and woke up later in the morning during—of all seasons—winter, when daylight hours on their Seattle…

Anxiety, autism, schizophrenia, and Tourette syndrome each have their own distinguishing characteristics, but a new study asks if circadian rhythm disruption may bridge these and most other mental disorders. In a new study in the journal Translational Psychiatry, scientists hypothesize that circadian rhythm disruption (CRD) is a psychopathology factor that a broad range of mental illnesses…

Ensuring your bedroom is pitch black at night—without light exposure from a television, window, cellphone, or even your alarm clock—is a simple way to reduce your risk of chronic disease. It was only about 130 years ago that electric light was invented, bringing with it drastic changes in the way humans function on a daily…
