Frequently Asked Questions
What is the Jet Lag Calculator?
The Jet Lag Calculator is a tool designed to estimate how long it will take your body to recover from crossing multiple time zones. It provides a schedule for adjusting your sleep and light exposure to minimize the effects of jet lag.
How is the recovery time calculated?
Recovery time is estimated based on the number of time zones crossed, the direction of travel (East or West), and individual factors such as age and usual sleep patterns. Generally, crossing time zones eastward requires more recovery time than westward.
Why is flying East harder than flying West?
Traveling East ('phase advancing') requires you to go to sleep earlier than usual, which is biologically harder for most people than staying up later ('phase delaying'), which happens when traveling West.
What do the 'Light Exposure' recommendations mean?
The calculator suggests specific times to seek bright light (sunlight) or avoid it. Light is the primary signal to your circadian clock; seeking light in the morning helps you wake up earlier, while avoiding it helps you stay awake later.
Can I use this calculator for road trips or train travel?
This tool is optimized for air travel where rapid time zone changes occur. It may not be accurate for ground travel, as your body adjusts more gradually when moving across zones slowly.
Does the calculator account for Daylight Saving Time?
Yes, provided you enter the accurate dates and locations. The tool automatically accounts for time zone offsets, including Daylight Saving Time or Summer Time variations for the specific regions.
