Jet Lag Disorder

Medically reviewed · Ratel Health editorial team · Sunday, 16 August 2026

A circadian rhythm sleep-wake disorder involving temporary sleep disruption caused by rapid travel across multiple time zones.

Overview

Jet lag disorder, a type of circadian rhythm sleep-wake disorder, involves a temporary mismatch between the body’s internal circadian clock and the external time cues of a new time zone, occurring after travel across at least two time zones.

Signs and Symptoms

Symptoms can include difficulty falling or staying asleep, excessive daytime sleepiness, reduced daytime alertness, and mild physical symptoms such as fatigue or gastrointestinal upset. Experiencing one or more of these symptoms does not necessarily mean that a person has this condition. Diagnosis requires an appropriate clinical evaluation.

Causes and Risk Factors

Jet lag results from the body’s internal circadian clock remaining synchronized to the time zone of origin while being exposed to a new local light-dark and activity schedule.

Diagnosis

A diagnosis should be made by a qualified healthcare professional following a comprehensive clinical assessment. Clinicians may use established diagnostic frameworks such as DSM-5-TR and/or ICD-11 as part of a comprehensive assessment.

Treatment

Treatment depends on the individual’s symptoms, clinical history, severity, age, co-occurring conditions, and other relevant factors.

Psychotherapy

Strategic light exposure and gradual adjustment of sleep-wake timing before and after travel can help realign the circadian clock.

Medication

Short-term use of melatonin around the new bedtime, or occasionally short-acting sleep aids, may be considered for significant symptoms. Medication decisions should be made with a qualified prescribing healthcare professional. Do not start, stop, or change a prescribed medication based solely on information on this page.

Living With Jet Lag Disorder

Gradually shifting sleep and meal times toward the destination time zone before travel, and getting daylight exposure at the right times after arrival, can speed adjustment.

When to Seek Professional Help

Professional evaluation may be appropriate if symptoms persist, worsen, cause significant distress, or interfere with work, school, or relationships.

Outlook

Symptoms are temporary and typically resolve within a few days as the body adjusts to the new time zone.
