Jetlag Recovery: How Biological Adaptation Works
Jet lag occurs when our internal biological clock (circadian rhythm) no longer matches the local time at the destination. This leads to fatigue, sleep disturbances, and poor concentration. The key to fast recovery lies in the targeted control of light and darkness.
Our brain uses light signals to decide when to release melatonin. Our planner tells you exactly when to seek bright light to advance your clock (for eastward flights) or delay it (for westward flights). Following a step-by-step plan over three days minimizes symptoms and lets you enjoy your stay sooner.
Tips for Faster Adjustment

No Alcohol: Avoid alcohol on the first day to prevent additional strain on your sleep cycle.
Frequently Asked Questions (FAQ)
helpWhy is light so important for jet lag?
Light is the strongest cue for our internal clock. It suppresses the sleep hormone melatonin. Targeted light exposure at the right time shifts your rhythm faster into the new time zone.
helpHow long does recovery take?
As a rule of thumb, it takes about one day per time zone crossed. Traveling East usually takes longer to adjust than traveling West.
helpShould I sleep immediately after landing?
Only if it's already nighttime at your destination. Try to stay awake until the local bedtime to adjust faster. A short power nap (max 20 min) can help.
helpWhat is the difference between East and West flights?
Westward flights (lengthening the day) are easier for most because the human internal clock is naturally slightly longer than 24 hours. Eastward flights require advancing the clock, which is harder for the body.
