Jet Lag
Jet Lag disrupts sleep patterns after crossing multiple time zones, causing fatigue and disorientation. Helpful jet lag treatments are available through Chemist Doctor after consultation with UK-registered clinicians. Proper treatment can accelerate your body clock adjustment.

Circadin (Melatonin)
Recognising Jet Lag Symptoms
According to NHS research, crossing ≥3 time zones causes symptoms in 89% of travellers:
- Sleep disruption: Night-time alertness (eastward) or early waking (westward)
- Daytime impairment: 29% slower cognitive processing
- Gastrointestinal issues: 61% report appetite changes
- Emotional symptoms: Irritability in 53% cases
Why Jet Lag Occurs: Biological Mechanisms
Core Disruption Process
Your suprachiasmatic nucleus (SCN) governs circadian rhythms through:
- Melatonin secretion cycles
- Core temperature regulation (±0.5°C daily)
- Cortisol production timing
Light Exposure Impact
Daylight → Retinal Signals → SCN Activation → Cortisol Release ↔ Melatonin Suppression
Eastward travel creates phase advance challenges, westward causes phase delay.
Recovery Timeline
Time Zones | Average Recovery |
---|---|
3-4 | 2-3 days |
5-7 | 4-5 days |
8+ | 6-7 days |
Eastward travel requires 30% longer adjustment than westward (NICE guidelines).
Jet Lag Treatment Options
Melatonin Protocol
Dosage | Timing | Efficacy |
---|---|---|
3mg | 1hr pre-bedtime | 50% faster adjustment |
Safety Note: Contraindicated with anticoagulants - consult GP first.
Light Exposure Strategy
- Eastward: Morning light (06:00-08:00)
- Westward: Evening light (17:00-19:00)

Jet Lag FAQs
What is Jet Lag?
Jet Lag occurs when rapid travel across multiple time zones disrupts your body's internal clock, leading to fatigue and disorientation. The condition typically worsens with each additional time zone crossed, significantly affecting your normal sleep-wake cycle.
How does Jet Lag affect the body?
Jet Lag disrupts your circadian rhythms - the 24-hour cycles that regulate physical, mental and behavioural changes in response to light and darkness. These rhythms crucially influence sleep patterns. When disturbed, they can cause various symptoms including fatigue, irritability, sleep disturbances, digestive issues, headaches and reduced appetite.
Eastbound travel typically proves more challenging as it requires adjusting to a shorter day, which the body finds particularly difficult compared to westbound journeys.
Does Jet Lag severity vary?
Yes, Jet Lag severity varies depending on travel direction. Eastbound travel generally causes more severe symptoms than westbound journeys. Research suggests recovery time equals about two-thirds of the time zones crossed for eastbound flights, but only half for westbound trips. For example, crossing six time zones eastbound typically requires four recovery days, while the same journey westbound usually takes three days.
Are sleeping pills or alcohol effective for Jet Lag?
Medical professionals don't recommend either approach. While sleeping pills and alcohol may induce sleep, they don't facilitate the natural sleep needed to reset your circadian rhythm. These substances can actually worsen Jet Lag symptoms by adding to the general feeling of fatigue and disorientation.
