Treatment
Medicines are not usually needed for jet lag. Jet lag often improves after a few days as your body clock adjusts to the new time zone. Sleeping tablets may be helpful if you're having problems sleeping (insomnia). But they can be addictive so should only be used for a short time and if symptoms are severe. Melatonin is a natural hormone released by the body in the evening to let your brain know it's time to sleep. Melatonin tabletsare not recommended on the NHS for jet lag because there's not enough evidence to show they work.
