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.

Missing one night of sleep may increase Alzheimer's biomarker, study finds

A preliminary study has found that when young, healthy men were deprived of just one night of sleep, they had higher levels of tau, a biomarker for Alzheimer's disease, in their blood than when they had a full, uninterrupted night of rest.

Body clock gene impairs defense against pneumonia

Most living things have an internal body clock which regulates when they sleep and when they wake up. A complex set of genes turning on and off, make this body clock run over roughly 24 hours, and a gene known by the acronym BMAL1 is one of the master regulators of this clock, controlling many other body clock genes and pathways.

Rutgers expert shares tips on how to minimize jet lag, sleep disruptions during the holidays

With shorter daylight hours, stress and travel to different time zones, the holiday season can disrupt our circadian rhythm and create sleep difficulties – making it even harder to avoid stress, enjoy time with family, and finally return to work.

Stress affects circadian rhythm, increases metabolic disease risk

Stress is a normal part of life, but too much of everything isn’t healthy. Every day, people from all walks of life experience stress of various degrees. A new study found that when stress has disrupted the circadian rhythm, the body’s internal clock, it can increase the risk of developing metabolic diseases.

High glucose impairs circadian clock function, may increase cardiovascular risk

High glucose in obesity appears to gum up the works of the circadian clocks inside our cells that help regulate the timing of many body functions across the 24-hour day and drive the risk of cardiovascular disease, scientists say.

Sleep DownUnder 2019 hosts leading experts to reveal latest snooze secrets

Kiwifruit, cannabis, tongue implants and smartphone apps are among the latest sleep aids in the spotlight at an international sleep conference to be held in Sydney this week.

Researchers identify an immune cell that helps keep time in the gut

As people go through their daily and nightly routines, their digestive tracts follow a routine, too: digesting food and absorbing nutrients during waking hours, and replenishing worn-out cells during sleep. Shift work and jet lag can knock sleep schedules and digestive rhythms out of whack.

Teenagers sleep 43 more minutes each night after intervention that reset their body clocks

Teenagers got 43 more minutes of sleep a night after a four-week intervention that reset their body clocks and helped them go to bed earlier, a study from the Stanford University School of Medicine has shown.

Study: Teen girls who stay up late are more likely to gain weight

Teen girls--but not boys--who prefer to go to bed later are more likely to gain weight, compared to same-age girls who go to bed earlier, suggests a study funded by the National Institutes of Health.

UC San Francisco scientists identify second 'short sleep' gene after 10-year search

After a decade of searching, the UC San Francisco scientists who identified the only human gene known to promote "natural short sleep" -- lifelong, nightly sleep that lasts just four to six hours yet leaves individuals feeling fully rested -- have discovered a second.

Biological clocks in plants regulate the effectiveness of widely-used herbicide

Plants can tell the time, and this affects their responses to certain herbicides used in agriculture according to new research led by the University of Bristol.

New computational model explores daily pain sensitivity rhythms

A new computational model successfully predicts how daily pain sensitivity rhythms affect pain processing, both in healthy adults and in people with neuropathic pain. Jennifer Crodelle of New York University and colleagues present these findings in PLOS Computational Biology.

Researchers study molecular mechanism of interplay of clock proteins for circadian oscillation

Organisms on this planet, including human beings, exhibit a biological rhythm that repeats about every 24 h to adapt to the daily environmental alteration caused by the rotation of the earth.

Researchers elucidate the mechanism underlying dead-zone generation in circadian clocks

Most organisms on Earth have circadian clocks. In mammals, the circadian pacemaker is located in the suprachiasmatic nucleus of the brain.

Circadian rhythm plays a part in weight loss

Weight watchers worldwide need to not only be careful about what to eat but also about the timing of the food intake finds a new study.

New study explains why heart failure patients have trouble with thinking and depression

Heart failure patients often have trouble with thinking and depression. A new study by University of Guelph researchers explains why and points to ways to prevent and treat both heart and brain maladies through the emerging field of circadian medicine.
