Time difference and jet lag: practical tips
Flying to the Dominican Republic from Europe means travelling west: your day is lengthened and you will go to bed later than usual. From the US East Coast the gap is 1 hour in winter and no difference in summer, so time-zone jet lag is slight. A few simple rules help you adjust to local time:
- Set your watch and phone to local time as soon as you board.
- Align meals and bedtime with local time from the first day.
- Plan a light first day, with no important meetings or long drives.
- Get out in daylight when you arrive and avoid long naps.
- If you take medication at fixed times, ask your doctor how to adapt the schedule to the time difference.

Jet lag: how flight direction affects you in the Dominican Republic
- Outbound from the UK (flying west): you « gain » 4 hours in UK winter and 5 hours in summer; your arrival day is lengthened and tiredness comes early in the local evening.
- Return to the UK (flying east): the opposite applies. Flying east shortens the day: plan a quiet day when you get home.
- Your usual night at home (23:00 – 07:00) corresponds to 19:00 – 03:00 in Santo Domingo from London in UK winter (18:00 – 02:00 during BST), and to 00:00 – 08:00 from New York during EST (23:00 – 07:00 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in Santo Domingo, the sun rises around 07:15 and sets around 18:23 in mid-January, and around 06:12 and 19:20 in mid-July (table above). After flying west, make the most of the late-afternoon light to stay up until the evening; this is the standard advice for shifting your body clock.
