Preliminary results from a new study suggest that several sleep-related symptoms are associated with decreased work productivity.
Pilot data from a recent study suggest that NFL teams have better performance during night games versus afternoon games due to advantages from circadian rhythms.
Nighttime snacking and junk food cravings may contribute to unhealthy eating behaviors and represent a potential link between poor sleep and obesity, according to a study by University of Arizona Health Sciences sleep researchers.
The brain's sewer system is a channel of communication that tells you when you are hungry, scientists find.
The first human study to look at how blood proteins vary over a 24-hour-period identified 30 with distinct time-of-day patterns and more than 100 that are disrupted by simulated night shift work
Disruption to normal daily circadian rhythms is associated with a greater susceptibility to mood disorders such as severe depression and bipolar disorder over the life course, according to the largest observational study of its kind involving over 91,000 people, published in The Lancet Psychiatry.
A mouse study published in JNeurosci finds that restricting food availability to one half of the day resets the normal timing of the signals that regulate food intake and reduces weight gain in mice fed a high-fat diet.These findings could inform future obesity research in humans.
For years, doctors have associated the BRCA1 and BRCA2 gene mutations with an increased risk of breast cancer. But researchers at Texas A&M University have now identified another gene that may have an impact on breast cancer --associated with the body's circadian rhythm.
Night shifts have an impact on genes regulating important biological processes and their expression can't adapt to new sleeping and eating patterns and that most of them stay tuned to their daytime biological clock rhythms.
For the first time, the lab of Nobel laureate Aziz Sancar measured DNA repair after cisplatin treatment throughout the entire genome of a mammal over the 24-hour circadian cycle. They found DNA repair of normal tissue was most robust predawn and pre-dusk in mice, and these could represent the best times for treatment using the anti-cancer drug cisplatin, though much more work needs to be done.
