Stretching your day
This is the “I have extra hours somehow” situation. Usually westbound. Usually easier. Still very easy to mess up if you wing it.
What it feels like
You can often stay awake later than local time suggests. That can help adaptation, but it can also push you into a weird second wind and late-night drift.
Simple stretching playbook
- Use in-flight sleep only as needed for fatigue, not as a full reset by default.
- Stay active after landing and ride local evening.
- Keep caffeine early enough that bedtime still works.
- If you nap, keep it short and deliberate.
Common failure mode
Feeling good in the afternoon, taking a long nap, then lying awake at 2am wondering how this happened.
