How long does jetlag adaptation take?

Generally about 1 day per hour of time difference. Eastward travel is harder to adapt to than westward.

Does melatonin help?

Short-term use can help with jetlag. A low dose (0.5-3mg) taken 30-60 minutes before desired bedtime is typical.

Why is light exposure important?

Light is the strongest signal for your circadian clock. Timed bright light exposure accelerates adaptation.
