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.

Study reveals how the body clock stays on track despite temperature changes

Researchers led by Gen Kurosawa at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan have used theoretical physics to discover how our biological clock maintains a consistent 24-hour cycle-even as temperatures change.

Study reveals how jet lag affects sleep timing and recovery

A collaborative study conducted by researchers at the Centre for Sleep and Cognition at the NUS Yong Loo Lin School of Medicine (NUS Medicine) and ŌURA found that while sleep duration recovers quickly, sleep timing and sleep architecture can take significantly longer to realign when traveling across time zones.

Liver-brain connection revealed as key to eating habits and metabolism

People who work the nightshift or odd hours and eat at irregular times are more prone to weight gain and diabetes, likely due to eating patterns not timed with natural daylight and when people typically eat.

'Visual system' protein appears to be key for stabilizing the body's circadian rhythms

Scientists at the Johns Hopkins University School of Medicine and the National Institutes of Health have identified a protein in the visual system of mice that appears to be key for stabilizing the body's circadian rhythms by buffering the brain's response to light.

Understanding the link between primary cilia, biological clock and wound healing

Nearly every organism on Earth follows a natural circadian rhythm that is coded by your cell's clock genes, which do exactly as you suspect from the name: regulate your body's rhythm on a 24-hour basis.

Is night shift work rewiring our appetite and driving weight gain?

Bristol University scientists reveal that night shift work disrupts the body's circadian rhythm, altering appetite-regulating hormones and leading to weight gain. The study, providing insights into metabolic health, may aid in developing treatments for eating disorders and obesity.

Sleep-wake cycle may play role in adolescent behavior problems

Mental health issues affect a significant percentage of children and adolescents worldwide, with behavior problems being among the most prevalent. Behavior problems in adolescence can lead to behavior disorders, contributing to adverse health outcomes, disability, diminished quality of life, and even premature mortality.
