Jet Lag: The Desynchronosis Problem

**Jet lag**, or "desynchronosis," occurs when you travel across multiple timezones so quickly that your internal biological clock is no longer in sync with the local solar time.

Why West is Best

Most travelers find it easier to adjust when traveling **West** (lengthening the day) than when traveling **East** (shortening the day). This is because the human internal clock naturally runs slightly longer than 24 hours. Extending the day slightly aligns better with our biology than forcing ourselves to go to sleep "early" relative to our home timezone.

The Recovery Rate

The general rule of thumb is that it takes about **one day per timezone crossed** for your body to fully adjust. During this time, your body is struggling to shift its core temperature, hormone production, and digestion cycles to match the new "anchor" points of light and dark.

The Solution of Light

The fastest way to cure jet lag is through strategic light exposure. By seeking bright sunlight at specific times of the day (relative to your destination), you can "force-reset" the SCN in your brain, accelerating the synchronization process.

Conclusion

Jet lag is a modern ailment caused by our ability to outpace the sun. On the Epoch Clock, the time changes instantly when you land, but your body remains a ghost in the machine of your previous location.
