Jet Lag

🌿 Overview

Jet lag is the foggy tiredness from flying across time zones, when your inner clock and the local clock disagree. It passes on its own — usually about a day per time zone — and natural daylight, sleeping and eating on local time, water, and gentle activity all help your body reset faster.

Jet lag is the worn-out, out-of-sync feeling you get after flying quickly across several time zones. Your body runs on an inner clock that tells it when to feel awake and when to feel sleepy. When you suddenly land in a place where the clock on the wall says one thing but your body still feels like it's the middle of the night, the two clocks disagree — and that mismatch leaves you tired, foggy, and unsettled. The more time zones you cross, the stronger it tends to be. Most people find that traveling east (losing hours) is harder than traveling west (gaining hours), because it's easier for the body to stay up later than to fall asleep earlier. A helpful rule of thumb is that your body takes about a day to adjust for each time zone you crossed. The good news is that jet lag passes on its own, and a few simple habits speed it along. Daylight is the strongest reset button there is: getting outside in natural light at the right time helps your inner clock catch up. Steady sleep, plenty of water, gentle movement, and easing onto the new schedule all help your body find its rhythm again.

Common signs

• Tiredness and trouble sleeping at the right local time
• Daytime grogginess and low energy
• Trouble concentrating or making decisions
• Irritability or feeling generally off
• Sometimes upset stomach or poor appetite

🔎 Why it happens

Common causes and triggers — spotting yours is often the first step to relief.

• Crossing several time zones faster than your inner clock can adjust
• Your body's natural sleep-wake rhythm being out of step with local time
• Long flights with poor sleep, dry cabin air, and little movement
• Traveling east, which is usually harder than traveling west
• Caffeine or alcohol on the trip, which disturb sleep further

✅ What to do

Gentle, practical steps you can take at home — start at the top.

1. Get outside in natural daylight at your destination — sunlight is the strongest helper for resetting your inner clock.
2. Shift onto the new schedule right away: eat meals and sleep by the local clock, not your home one.
3. Drink plenty of water before, during, and after the flight; cabin air is very drying.
4. Take a gentle outdoor walk after you arrive to wake the body up and ease stiffness.
5. If you arrive in the evening, soakResting a body part (or the whole body) in warm, treated water. How to make a soak → up some extra rest; if you arrive by day, stay up until a normal local bedtime.
6. Skip caffeine and alcohol on the trip, and try a calming chamomile or lemon balm teaA warm drink made by steeping herbs in hot water. How to make a tea → to settle before sleep.

🍽️ Eating to help

Food is one of the gentlest medicines — small, steady changes help most.

Favor these

• Plenty of water and watery fruits and vegetables
• Light, simple plant-based meals eaten on the new local schedule
• Calming herbal teas like chamomile or lemon balm before bed

Go easy on

• Caffeine, especially later in the day
• Alcohol, which fragments sleep
• Heavy, rich meals late at night

Eat by the new clock and hydrate well — lining up meals and light with local time helps your body catch up faster.

📜 A note from history

Travelers have long found that fresh air, sunlight, and easing onto local meal and sleep times settle the body after a long journey.
