Synopsis of Jet Lag

Jet lag is a temporary sleep and body rhythm disorder that occurs when a person travels quickly across multiple time zones, causing a disruption in the body’s internal clock (circadian rhythm). The mismatch between your internal body clock and the new local time affects sleep, digestion, mood, and energy levels.

Jet lag is more severe when traveling eastward (e.g., from New York to Europe) because it's harder to advance your body clock than delay it. The severity depends on the number of time zones crossed, direction of travel, age, and individual sensitivity.

Common symptoms include:

  • Insomnia or disrupted sleep

  • Daytime fatigue

  • Difficulty concentrating

  • Digestive issues (e.g., constipation or nausea)

  • Mood changes or irritability

  • General malaise or "out of sync" feeling

When to see a doctor:
Jet lag is self-limiting and usually resolves within a few days, but if sleep disturbances persist or severely affect functioning, consult a physician—especially if you travel frequently.

Natural remedies for Jet Lag

Gradually Adjust Sleep Schedule Before Travel: Shift bedtime earlier or later to match the destination time zone.

Get Sunlight Exposure at the Destination: Natural light helps reset your internal clock.

Stay Hydrated and Avoid Alcohol or Caffeine in Transit: These worsen dehydration and disrupt sleep.

Use Short Naps Wisely: Keep naps under 30 minutes to avoid sleep inertia.

Melatonin (under guidance): Can help reset circadian rhythm, especially when taken 30–60 minutes before the new bedtime.
