Evidence-based recommendations
Each recommendation below is graded by how strongly published research supports it, with the source it comes from. Optimal timing depends on your travel direction, the number of time zones crossed and your own circadian phase, so treat the schedule as a starting point.
Seek morning light
StrongBright light after your destination wake time helps advance your body clock when travelling east.
CDC Yellow Book 2026Limit light in the local evening
StrongLight at the wrong hour can push your clock the opposite way, so dim screens and lights before your target bedtime.
NIH — Circadian rhythmsShift bedtime earlier before departure
ModerateMoving sleep and wake times 30-60 minutes earlier for a few nights gives your clock a head start on an eastward trip.
CDC Yellow Book 2026Live on destination time on arrival
ModerateSleeping, eating and being active on local time gives your body consistent cues about the new day.
CDC Yellow Book 2026Use caffeine early, not late
Practical adviceCaffeine can help you stay awake during local daytime, but late doses tend to delay sleep onset.
CDC Yellow Book 2026Protect sleep around the flight
Practical adviceArriving without a large sleep debt makes the first days easier, even when few time zones are involved.

How we grade evidence
- Strong
- Consistently supported by controlled circadian research and current public-health guidance.
- Moderate
- Supported by research, but effect size and best timing vary between individuals and studies.
- Practical advice
- Sensible travel habits with limited direct evidence for shifting the body clock.
This is general travel information, not medical advice. Talk to a clinician before using melatonin or sleep medication, especially if you are pregnant, take other medication or have a sleep disorder.
Flying the other way?Atlanta → Bogotá
Flying from Bogotá to Atlanta
The flight from Bogotá (BOG) to Atlanta (ATL) covers approximately 3,389 kilometers (2,106 miles) based on the great-circle distance between both airports. This is the shortest theoretical path over Earth's surface, though actual flight paths may be slightly longer due to air traffic routing, weather avoidance, and airspace restrictions.
The estimated non-stop flight time is 4h 19m to 5h 3m, assuming a modern jet cruising at approximately 850 km/h. This gate-to-gate estimate includes time for taxi, takeoff, climb, cruise, descent, and landing. Actual duration varies based on wind conditions — particularly the jet stream — aircraft type, and airport congestion at both ends.
Atlanta is 1 hour ahead of Bogotá. Travelers crossing 1 time zone eastward can expect mild jet lag, with full circadian adjustment typically taking about 1 day.
Since you're traveling eastward, your body clock needs to advance — meaning you'll need to go to bed earlier and wake up earlier than feels natural. Strategic morning light exposure at your destination is the most effective way to accelerate this adjustment.

Flight path, direction and distance
Leaving Bogotá, the great-circle track to Atlanta starts on an initial bearing of about 343° (NNW). The route measures 3,389 km, or 1,830 nautical miles — the unit airlines actually plan with. Because the shortest path on a sphere is a curve rather than a straight line on a flat map, the real track may look like it bends far north or south of the direct line you would draw on a wall map.
At this length the sector is a medium-haul flight of around 4h 41m, typically operated by narrow-body or smaller wide-body aircraft with one full meal service.
This is an international sector, so allow additional time for immigration and customs on arrival — typically 30 to 60 minutes on top of the block time before you are landside.
Departure and arrival times: Bogotá to Atlanta
Using an estimated block time of 4h 41m and the current offset between the two cities, this table shows what local time you would land in Atlanta for common departure times from Bogotá. Use it to pick a departure that puts your arrival in daylight, which makes the first day of adjustment much easier.
| Departure (Bogotá) | Arrival (Atlanta) | Arrival day |
|---|---|---|
| 06:00 | 11:41 | Same day |
| 10:00 | 15:41 | Same day |
| 14:00 | 19:41 | Same day |
| 18:00 | 23:41 | Same day |
| 22:00 | 03:41 | Next day |
Times are estimates based on great-circle distance and current time zone offsets, not airline schedules. Always confirm with your carrier.
Daylight: Bogotá vs Atlanta
Daylight length is what actually resets your body clock, and it differs between Bogotá and Atlanta through the year. In Atlanta the day runs from about 9.9 h to 14.4 h across the four dates below, which changes how much morning or evening light you can realistically get after landing.
| Date | Sunrise Bogotá | Sunrise Atlanta | Sunset Atlanta | Day length vs origin |
|---|---|---|---|---|
| March equinox · March 20 | 06:02 | 07:43 | 19:49 | ±0 |
| June solstice · June 21 | 05:46 | 06:27 | 20:51 | +2 h |
| September equinox · September 22 | 05:46 | 07:25 | 19:36 | ±0 |
| December solstice · December 21 | 05:59 | 07:38 | 17:33 | −1.9 h |
Your light window in Atlanta
Flying east, light in the first hours after sunrise pulls your clock earlier. In Atlanta that puts the useful window at roughly 07:43–10:43. Keep light low around 16:49–19:49, when late light would push your clock the wrong way. Timing depends on your own circadian phase, so treat these as starting points.
Body clock time on arrival in Atlanta
Before any adjustment, your body still runs on Bogotá time. When it is 08:00 in Atlanta, your body thinks it is 07:00 — which is why local mealtimes and meetings can feel so far off on day one.
| Atlanta clock | Your body clock | What your body expects |
|---|---|---|
| 06:00 | 05:00 | Waking up, low alertness |
| 08:00 | 07:00 | Waking up, low alertness |
| 12:00 | 11:00 | Awake and alert |
| 16:00 | 15:00 | Awake and alert |
| 20:00 | 19:00 | Winding down |
| 23:00 | 22:00 | Sleep |
Daylight saving on this route in 2026
Bogotá keeps the same offset all year (America/Bogota), with no daylight saving changes.
Atlanta (America/New_York) changes clocks on March 8 (UTC-5 → UTC-4), November 1 (UTC-4 → UTC-5).
Because the two zones do not switch on the same dates, the gap between Bogotá and Atlanta is not fixed: it is 0 h in January and 1 h in July. Check the offset for your actual travel date, not a generic value.
Estimated adjustment curve
Eastward travel asks your body clock to run earlier, which it does more slowly — roughly an hour a day. For 1 time zone that models out to about 1 day before local time and body time line up.

Return trip: Atlanta back to Bogotá
| Leg | Direction | Time zones | Modelled recovery |
|---|---|---|---|
| BOG → ATL | eastward | 1 | 1 day |
| ATL → BOG | westward | 1 | 1 day |
The trip home is usually the easier half of this route: about 1 day outbound versus 1 day on the way back, since the return direction matches the way your clock drifts naturally.
