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.

Physician explains how poor or low-quality sleep hinders common resolutions

Making New Year's resolutions is easy. Keeping them — beyond a couple of weeks, at least — is tough.

Johns Hopkins scientists find link between sleep/wake cycles and core body temperature

A clump of just a few thousand brain cells, no bigger than a mustard seed, controls the daily ebb and flow of most bodily processes in mammals -- sleep/wake cycles, most notably.

TSRI study reveals how circadian clocks may influence cancer growth

A new study led by scientists at The Scripps Research Institute describes an unexpected role for proteins involved with our daily "circadian" clocks in influencing cancer growth.

Researchers identify mechanism of how circadian clocks in neurons encode daily rhythms of excitability

Molecular clocks in cells throughout the body control many physiologic changes in a 24-hour day/night circadian rhythm -- among them the timing of sleep and wakefulness.

Study provides insight into how the brain's biological clock regulates physiological function

The brain's biological clock stimulates thirst in the hours before sleep, according to a study published in the journal Nature by McGill University researchers.

Regulating mealtimes during days off can help alleviate jet-lag in long-haul cabin crew

A study published today in the journal Psychology and Health has found that jet-lag in long-haul cabin crew is alleviated when meal times are regulated on their days off.

Shift work alters internal body clock and leads to strokes, serious brain implications

Statistics show that some 15 million Americans don't work the typical nine-to-five. These employees (or shift workers), who punch in for graveyard or rotating shifts, are more prone to numerous health hazards, from heart attacks to obesity, and now, new research, published in Endocrinology, shows shift work may also have serious implications for the brain.

Salk scientists discover REV-ERBα protein that controls strength of circadian rhythm

At noon every day, levels of genes and proteins throughout your body are drastically different than they are at midnight. Disruptions to this 24-hour cycle of physiological activity are why jet lag or a bad night's sleep can alter your appetite and sleep patterns for days--and even contribute to conditions like heart disease, sleep disorders and cancers.

Sleep hormone melatonin may be responsible for type 2 diabetes risk among overnight workers

A new experimental and clinical study from Lund University in Sweden shows that the sleep hormone melatonin impairs insulin secretion in people with a common gene variant.

Working in night shifts may increase risk of coronary heart disease

Working at night is unhealthy for the heart and increases the risk of sustaining coronary heart disease, meaning a disease of the coronary arteries. This is the result of a current, and one of the largest American cooperation studies under the management of Eva Schernhammer of the epidemiology division of MedUni Wien, which was published in the top journal JAMA today. First author is Celine Vetter of Harvard University in Boston.

Scientists identify key pathway that regulates 'switch' between wakefulness and sleep

Falling asleep and waking up are key transitions in everyone's day. Millions of people have trouble with these transitions - they find it hard to fall asleep or stay asleep at night, and hard to stay awake during the day. Despite decades of research, how these transitions work - the neurobiological mechanics of our circadian rhythm - has remained largely a mystery to brain scientists.

Springing forward one hour may lead to increased heart attack risk

Many people may groan about losing an hour of sleep March 13, but there may be a more serious reason to be mindful of daylight saving time.

Human body clock study paves way for drug treatment of osteoarthritis

A University of Manchester biologist has for the first time established that the painful and debilitating symptoms endured by osteoarthritis sufferers are intrinsically linked to the human body clock.

Lucimed offers Luminette light therapy glasses for people suffering from seasonally induced issues

For millions of people, the arrivalof fall and winter are unwelcome events. A change in seasons often brings a change in their physical and mental health, due to fewer hours of sunlight.

Lack of adequate sleep can interfere with fundamental cellular process

Lack of adequate sleep can do more than just make you tired. It can short-circuit your system and interfere with a fundamental cellular process that drives physical growth, physiological adaptation and even brain activity, according to a new study from the University of Tennessee, Knoxville.

Jet lag-like sleep disruptions promote memory problems, chemical alterations in the brain

Chemical changes in brain cells caused by disturbances in the body's day-night cycle may be a key underlying cause of the learning and memory loss associated with Alzheimer's disease, according to a University of California, Irvine study.

Melatonin and the circadian rhythm: an interview with Professor Kennaway, University of Adelaide

The production of melatonin is controlled by a part of the brain called the suprachiasmatic nucleus (SCN) and its timing fine-tuned by our exposure to light during the morning.

AASM's new guideline provides updated recommendations for treatment of circadian rhythm sleep-wake disorders

A new clinical practice guideline published by the American Academy of Sleep Medicine provides clinicians with updated recommendations for the treatment of intrinsic circadian rhythm sleep-wake disorders (CRSWDs).

New article provides advice on handling mid-air health crises

A medical emergency that strikes in mid-air is a scary prospect for any traveler, but it presents a particularly complex situation for physicians and other healthcare providers.

Neuroscientist discovers how animal's biological clock wakes up, goes to sleep

Fifteen years ago, an odd mutant fruit fly caught the attention and curiosity of Dr. Ravi Allada, a circadian rhythms expert at Northwestern University, leading the neuroscientist to recently discover how an animal's biological clock wakes it up in the morning and puts it to sleep at night.
