Jet Lag News and Research

RSS

Jet lag, medically referred to as "desynchronosis," is a physiological condition which is a consequence of alterations to circadian rhythms; it is classified as one of the circadian rhythm sleep disorders.

Research offers focused explanation for cardiac arrest predilection for morning hours

Evidence from people with heart disease strongly supports the existence of the molecular link first discovered in laboratory mice between the body's natural circadian rhythms and cardiac arrest or sudden cardiac death (SCD) - the No. 1 cause of death in heart attacks, a scientist said here today.

Researchers identify potential drug target to recover from jet lag, disruptions in circadian system

University of Notre Dame researchers, as part of a collaborative effort, have identified a protein that potentially could be a target for drugs that would help people recover faster from jet lag and better adjust their circadian rhythms during rotational shift work.

Research findings may lead to treatments for disorders triggered by circadian clock dysfunction

Overnight flights across the Atlantic, graveyard shifts, stress-induced insomnia are all prime culprits in keeping us from getting a good night's sleep. Thanks to new research from McGill University and Concordia University, however, these common sleep disturbances may one day be put to bed.

Study reveals circadian disruption is a risk factor in alcoholic liver disease

Thirty percent of severe alcoholics develop liver disease, but scientists have not been able to explain why only a subset is at risk. A research team from Northwestern University and Rush University Medical Center now has a possible explanation: disrupted sleep and circadian rhythms can push those vulnerable over the edge to disease.

MIT study shows that SIRT1 gene plays key role in controlling circadian rhythms

Human sleeping and waking patterns are largely governed by an internal circadian clock that corresponds closely with the 24-hour cycle of light and darkness. This circadian clock also controls other body functions, such as metabolism and temperature regulation.

Scheduled exercise, regular meals and periodic warming relieve symptoms of osteoarthritis

Scheduled exercise, regular meals and the periodic warming and cooling of joints could be used to relieve the symptoms of osteoarthritis according to scientists at The University of Manchester. Their research may also help explain why older people are more prone to developing this common joint disorder.

Brandeis University researchers to receive Wiley Prize in Biomedical Sciences

Deborah E. Wiley, Chair of The Wiley Foundation, John Wiley & Sons, Inc., announced today that the twelfth annual Wiley Prize in Biomedical Sciences will be awarded to Dr. Michael Young, Rockefeller University, Dr. Jeffrey Hall, Brandeis University (Emeritus), and Dr. Michael Rosbash, Brandeis University.

Study reveals body's food clock on a molecular level

If the sinful excess of holiday eating sends your system into butter-slathered, brandy-soaked overload, you are not alone: People who are jet-lagged, people who work graveyard shifts and plain-old late-night snackers know just how you feel.

GSU project to study how the body's internal clock is reset

Georgia State University's H. Elliott Albers, the Regents' Professor of Neuroscience and director of the Center for Behavioral Neuroscience, has received a four-year, $1.3 million grant from the National Institutes of Health to study how the body's internal clock is "reset," a key to understanding more about sleep and other disorders affecting human health.

Researchers investigate effects of sleep architecture on hunger

A new study shows that both length of time and percentage of overall sleep spent in different sleep stages are associated with decreased metabolic rate, increased hunger, and increased intake of calories (specifically from fat and carbohydrates). The findings suggest an explanation for the association between sleep problems and obesity.

Combination of two neuroprotective therapies shows promise against Alzheimer's

The combination of two neuroprotective therapies, voluntary physical exercise, and the daily intake of melatonin has been shown to have a synergistic effect against brain deterioration in rodents with three different mutations of Alzheimer's disease.

Sleep disorder treatment: an interview with Dr Seth Lederman, President and CEO of Tonix Pharmaceuticals

Sleep disorders are a large area. We are focused on one particular type of sleep disturbance called “non-restorative” sleep. People with this problem do sleep, but they don’t wake up feeling refreshed or feeling that their sleep has had the restorative effects of healthy sleep.

Understanding photoreceptor proteins could lead to cancer drug therapy

How does a plant know when to sprout a leaf, fold its petals or bloom? Why do humans experience jet lag after a trip abroad?

TAU researcher reveals link between plant and human biology

Increasingly, scientists are uncovering surprising biological connections between humans and other forms of life. Now a Tel Aviv University researcher has revealed that plant and human biology is much closer than has ever been understood - and the study of these similarities could uncover the biological basis of diseases like cancer as well as other "animal" behaviors.

Lack of sleep can influence the way you perform certain tasks

Anyone that has ever had trouble sleeping can attest to the difficulties at work the following day. Experts recommend eight hours of sleep per night for ideal health and productivity, but what if five to six hours of sleep is your norm? Is your work still negatively affected? A team of researchers at Brigham and Women's Hospital (BWH) have discovered that regardless of how tired you perceive yourself to be, that lack of sleep can influence the way you perform certain tasks.
