Timeshifter and Melatonin are two methods that can help with adjusting to different time zones and combating jet lag.

Timeshifter is a mobile app that provides personalized advice on how to adjust your sleep schedule, exposure to light, and caffeine intake to minimize the effects of jet lag. It takes into account your travel itinerary and provides a plan to gradually shift your body’s internal clock to the new time zone.

Melatonin, on the other hand, is a hormone that is naturally produced by the body to regulate sleep-wake cycles. It can also be taken as a supplement to help adjust to new time zones. Melatonin supplements are most effective when taken at the appropriate time, usually a few hours before bedtime in the new time zone.

Both Timeshifter and Melatonin can be useful tools for travelers who frequently cross time zones and want to minimize the impact of jet lag on their sleep and overall well-being.
