Jet lag happens when your body clock is out of sync with local time. Arriving in New York from Europe, you’ll feel tired in the early evening and wake very early; from Asia, the shift is larger and harder; from the West Coast, a red-eye leaves you short of sleep. The most effective tools are light exposure at the right times, a smart first-day schedule, hydration, and strategic rest. A general rule of thumb is that the body adjusts by roughly one time zone per day, so plan important meetings accordingly.

By origin

Arriving from Typical challenge Strategy
Western Europe (5–6 hours ahead) Sleepy by evening, early waking Get afternoon daylight; stay up until local evening
Asia (12–13 hours) Major disruption Consider arriving a day early; nap briefly
West Coast red-eye Sleep deprivation Rest before meetings; light breakfast; daylight

Before the flight

  • Shift your sleep an hour or so toward New York time in the days before.
  • Choose flights that land in the afternoon or evening when possible.
  • Plan light meals and hydration.

On arrival

  • Get daylight, especially in the afternoon after flights from Europe.
  • Avoid long naps; a short one (20–30 minutes) can help.
  • Schedule demanding meetings for your body’s best hours.
  • Let your chauffeur handle the drive — don’t drive yourself while jet-lagged. Read red-eye arrival tips.

Caffeine, alcohol and supplements

Use caffeine strategically in the morning, limit alcohol, and consult a doctor before using sleep aids or supplements.

First-day schedule

A good first day: arrive, check in, walk outside in daylight, light dinner, early night. Read international travel checklist.

Returning home

Jet lag hits again on the way back. After returning to New York from Asia or Europe, plan a lighter schedule for the first day or two, and book a car home rather than driving from the airport.

Frequent travelers

Travelers crossing time zones often keep a consistent routine: the same sleep strategy, exercise on arrival and regular meal times. Consistency helps the body adjust faster.
