What makes the Las Vegas–Dallas route different

Arrival strategy for Dallas
Arriving in Dallas after a 2-hour eastward shift, your body will think it is 2 hours earlier than the local clock shows. If you arrive in the morning, push through fatigue and get outside in bright daylight. If you arrive in the evening, eat a light meal and go to bed at the local time — you may wake early, but resist getting up until at least 05:00.

How your body clock maps to local time upon arrival, before any adjustment.
| Dallas Time | Your Body Clock (Las Vegas) | How You Feel | Recommendation |
|---|---|---|---|
| 06:00 | 04:00 | Early wake phase. Groggy, low energy. | Light physical activity helps. Coffee is acceptable if 8+ hours before target bedtime. |
| 09:00 | 07:00 | Morning alertness building. Moderate energy. | Good window for bright light exposure if adjusting eastward. |
| 12:00 | 10:00 | Peak morning alertness on body time. | Productive window. Use this energy for important tasks. |
| 15:00 | 13:00 | Post-lunch dip. Moderate energy. | Brief 20-min nap acceptable if severely fatigued. Avoid long naps. |
| 18:00 | 16:00 | Afternoon alertness on body time. | Good window for light exposure if adjusting westward. |
| 21:00 | 19:00 | Evening wind-down. Melatonin starting to rise. | Dim lights and avoid screens if you need to stay awake longer. |
| 00:00 | 22:00 | Natural sleep window on body time. | Ideal time to sleep if it aligns with local night. If not, use bright light to delay. |
| 03:00 | 01:00 | Deep sleep phase. Intense drowsiness likely. | If awake, use bright light to push clock forward. Avoid driving or complex tasks. |
