Taking melatonin as a supplement helps reset the sleep-wake cycle during travel across more than 5 time zones, when combined with the avoidance of stimulants.

The use of melatonin to mitigate the effects of jet lag is widely documented and supported by research. A meta-analysis published in The Cochrane Library confirms that melatonin is remarkably effective at reducing jet lag symptoms, particularly when crossing multiple time zones. The mechanism involves helping the biological clock resynchronize with the new light environment, which validates the concept of providing support rather than forced sedation. The observation regarding stimulants like caffeine is consistent with good sleep hygiene practices, as these substances can counteract the beneficial effects on desired sleepiness. The recommendation for short-term use (a few days) aligns with standard practices suggested by experts to avoid long-term interference with natural production. No points here appear to be exaggerated or lacking a solid scientific basis.
