Jet Lag from India to the USA: A Simple Plan That Works (2026)

Quick answer: Flying from India to the USA moves your body clock back by about 9.5 to 13.5 hours, depending on the city. Most people feel normal again in about 2 to 7 days. You can make it easier by shifting your sleep a little before you fly, setting your watch to US time on the plane, staying awake until local bedtime on the first day, and getting daylight at the right times.

This guide gives a simple plan you can follow, explains why the big gap is tricky, and shows what to do for each US city. It is general travel advice, not medical advice.

Key takeaways

• The gap is 9 hours 30 minutes to New York in US summer and 13 hours 30 minutes to Los Angeles in US winter.
• Start shifting your sleep 2 to 3 days before you fly, even by one hour a day.
• On the plane, switch to US time and sleep only when it is night in the USA.
• On the first day, stay awake until about 9 to 10 PM local time and get outdoor light.
• Keep naps under 30 minutes in the first few days.
• Ask a doctor before using melatonin or sleep aids, especially if you take other medicine or have a health condition.

How big is the time gap?

India uses IST (UTC+5:30) all year. The USA changes its clocks, so the gap is different in summer and winter. You can check the exact gap for your travel date with our India to USA time difference tool.

Under current US rules, daylight saving time ends on 1 November 2026 and starts again on 14 March 2027, so check which gap applies on the day you land.

Why this trip can feel hard

Your body has an internal clock that follows light and dark. When you land in a place where the clock on the wall is 10 to 13 hours different, your body still thinks it is the Indian day. That is why you may feel wide awake at 3 AM in Chicago and sleepy at lunchtime.

A common rule says flying west is easier than flying east, because it is simpler to stay up later than to sleep earlier. That is often true, but with a gap close to 12 hours, as in Denver and Los Angeles, day and night are almost reversed. In that case the rule matters less, and the plan below matters more.

A simple jet lag plan, step by step

2 to 3 days before you fly

If your schedule allows, go to bed and wake up about 1 hour later each day. Even a small shift helps. If you cannot change your routine, do not worry. The steps on the plane and after landing matter more.

On the flight

• Set your watch and phone to US time when you board.
• Drink water regularly. Go easy on alcohol and caffeine.
• Try to sleep only when it is night at your destination. If it is daytime there, stay awake with a film, a book or a short walk in the aisle.
• Wear comfortable clothes and carry an eye mask and earplugs if they help you sleep.

The day you arrive

• Stay awake until a normal local bedtime, around 9 to 10 PM.
• Get outdoor daylight in the afternoon if you can. Light tells your body what time it is.
• If you must nap, keep it under 30 minutes and finish before 3 PM local time.
• Eat meals at local times, even if you are not very hungry.

The next 2 to 5 days

• Wake up at about the same local time each day. An alarm helps in the first days.
• Get light in the morning and avoid bright screens late at night.
• If you wake very early, stay in a dim room and try to fall asleep again.
• Plan lighter days at first. Avoid important meetings or driving long distances in the first day if you can.

The Jet lag plan tab in our time planner shows these steps for the city you choose.

What to do for each city

• New York: the smallest gap. Most people adjust in about 2 to 4 days.
• Chicago: about one hour more than New York. Expect a few days of early waking.
• Denver: a gap of 11.5 to 12.5 hours. Daylight on the first afternoon is especially useful.
• Los Angeles: the biggest gap. Many people need up to a week, so plan an easy first few days.

These are general ranges, and people differ a lot. Age, sleep habits, the flight time and stress can all change how you feel.

Coming back to India

The trip home moves your body clock forward by the same number of hours, which many people find harder. Reverse the plan: go to bed a little earlier in the days before you fly, get morning light after you land in India, and stay awake until your normal Indian bedtime on the first day. Use the direction option in the tool to see the plan for the flight home.

Before you go: a short checklist

• Check the time gap for your travel dates with the India to USA time tool.
• Read our tips for a first long-haul flight.
• Look at flight booking tips if you are still choosing a flight.
• Check entry rules and visa needs on official government websites before you travel.

A note on melatonin and sleep aids

Some travellers use melatonin or sleep medicine to adjust. Rules and products differ from country to country, and they are not right for everyone. Talk to a doctor or pharmacist first, especially if you take other medicine, are pregnant, or have a sleep or health condition. This page does not recommend any product or dose.
