๐Ÿง  Circadian Rhythm & Jet Lag Optimization

โœˆ๏ธ Direction of Travel: Westbound (Easier)

Flying West lengthens your day cycle, which is generally easier for the body clock to adapt to. Stay awake until local evening bedtime.

๐Ÿ’ง In-Flight Hydration Rule

Aircraft cabin humidity is typically 10-20% (dryer than Sahara desert). Drink at least 250ml of water for every hour in flight and avoid alcohol/excess coffee.

๐Ÿ’ฌ Frequently Asked Questions

Got questions about Flight Duration & Time Zone Calculator? Here are the most common answers.

How is the flight duration estimated?โ–ผ

We calculate the spherical Great Circle distance using the Haversine mathematical formula, assuming an average commercial jet cruising speed (~830 km/h) plus 35 minutes for ascent, descent, and vectoring.

Does this account for time zone differences upon landing?โ–ผ

Yes. The destination arrival time is converted into the destination citys local clock time, including date changes (+1 day or -1 day).

Why do flights eastward feel harder for jet lag?โ–ผ

Flying East shortens your natural 24-hour body rhythm, making it harder for your brain to advance its internal sleep clock compared to westward travel.
