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.

How does gut microbiota impact mental health in 18–25s?

In a recently published article in the International Journal of Molecular Sciences, scientists have described the importance of the gut-brain-microbiota axis in establishing optimal mental health in emerging adulthood (ages 18–25).

The relationship between circadian misalignment and the risk of COVID-19 infection

An interesting new study links changes in the daily rhythms of the human body with the risk of COVID-19.

Study hints a potential difference in molecular clockworks between the master and slave clock neurons

From tiny fruit flies to human beings, all animals on Earth maintain their daily rhythms based on their internal circadian clock.

Can meal times affect your risk of glucose intolerance?

In this interview, we speak to Dr. Frank Scheer and Dr. Sarah Chellappa about their latest research that investigated the effect meal times has on glucose intolerance.

Daytime meals can help regulate bloodstream glucose levels in night shift workers

What are the effects of eating during the nighttime instead of the daytime? New research, focused on a simulation of night shift work, may hold implications for people eating at atypical times -; like those experiencing jet lag, circadian rhythm sleep disorders, or who tend to sleep late during the weekends.

Study reports first-ever modeling of the electrical activity of circadian clock neurons in diurnal species

It's no secret that jet lag and night-shift work can wreak havoc on the way our body's internal clock syncs up our daily wake-sleep cycle, known as circadian rhythm, but now researchers say they are a step closer to understanding how the brain creates behavioral rhythms optimized for diurnal, rather than nocturnal, life.

Npas4 gene may be a master timekeeper for the brain's circadian clock

A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research led by UT Southwestern scientists suggests.

Light-controlled on/off switch helps control biological clock in cultured cells, explanted tissue

The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally.

New study reviews effect of coffee on people's sleep and wake cycles

The Institute for Scientific Information on Coffee (ISIC) published a new report today, titled 'Coffee and sleep in everyday lives', authored by Professor Renata Riha, from the Department of Sleep Medicine at the University of Edinburgh.

Researchers discover unexpected role for the clock gene in prostate cancer progression

Our biological or circadian clock synchronizes all our bodily processes to the natural rhythms of light and dark. It's no wonder then that disrupting the clock can wreak havoc on our body.

Scientists investigate how cell membrane and COVID-19 virus impact each other

The cell membrane is the cell's outermost line of defense against SARS-CoV-2, the novel coronavirus responsible for COVID-19 disease.

Studies show how individual cells maintain their internal clocks

Two new studies led by UT Southwestern scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means.

2 Jul 2020

Scientists demonstrate importance of aligning internal circadian clock with day-night cycles

Timing is everything. A fresh example supporting the old saying has been found in connection with the systems regulated by biological clocks.

Changing clocks is bad for your health, but which time to choose?

Changing over to daylight saving time — a major annoyance for many people — may be on its way out as lawmakers cite public health as a prime reason to ditch the twice-yearly clock-resetting ritual.

14 Feb 2020

Study explains how certain mutations can shorten biological clock timing

A new study of molecular interactions central to the functioning of biological clocks explains how certain mutations can shorten clock timing, making some people extreme "morning larks" because their internal clocks operate on a 20-hour cycle instead of being synchronized with the 24-hour cycle of day and night.

13 Feb 2020

Novel melatonin receptor molecules potentially address circadian rhythm disturbances

Like breathing or blinking, behaviors regulated by our circadian rhythms, such as digestion and sleep-wake cycles, go unnoticed by most people.

10 Feb 2020

Researchers receive $1 million grant to study effects of bacteria on the brain

With a $1 million grant from the W. M. Keck Foundation, neuroscience researchers at Washington State University and the University of Massachusetts Amherst will explore whether variations in brain levels of bacterial fragments can account for life's sleep/wake and 24-hour cycles, known as circadian rhythms.

Fat cells can sense light, not getting enough raises risk of metabolic diseases

All life forms need sunlight to survive and not getting enough may impact health and well-being. There is a growing body of evidence that getting enough sunlight can promote optimum health. A new study supports this claim as scientists found that fat cells deep in the skin can detect sunlight and not getting enough can increase the risk of metabolic disruption.

21 Jan 2020

Lack of exposure to sunlight may increase metabolic syndrome risk

Yes, fat cells deep under your skin can sense light. And when bodies do not get enough exposure to the right kinds of light, fat cells behave differently.

Irregularity in eating schedules during weekend linked to obesity

A new study by the University of Barcelona concluded that irregularity in eating schedules during the weekend, named by the authors as eating jet lag, could be related to the increase of body mass index (BMI), a formula that measures weight and height to determine whether someone's weight is healthy.
