Jetlag: Causes, Symptoms, and Treatment

Travellers often experience jet lag. It disrupts the body's circadian rhythm, which regulates sleep and wakefulness. Jet lag can induce physical and mental exhaustion. This page discusses jet lag causes, symptoms, treatment, and prevention.

I. Intro

Due to quick cross-time zone travel, jet lag arises. Travellers, especially those who cross time zones, often get it. Jet lag causes weariness, sleep problems, irritability, and difficulties concentrating. Jet lag can last for days, depending on the person.

Jetlag definition

When the body's internal clock mismatches the local time, jet lag occurs. The circadian rhythm regulates sleep, wakefulness, and appetite. Travelling across time zones disrupts your circadian cycle, making it difficult for your body to acclimatise.

Jetlag causes

Rapid cross-time zone travel interrupts the circadian rhythm, causing jet lag. Jet lag severity varies on time zones traversed and travel orientation. Eastward travel loses time, making it hard to acclimatise to an earlier bedtime. Your body may struggle to acclimatise to a later bedtime when travelling westward.
