This article issues a call to action for international travelers to participate in a research study aimed at validating chronoacupuncture for treating jet lag. The underlying theory, which has existed for decades but lacks scientific proof, suggests that stimulating specific horary acupuncture points based on the destination's time zone during travel can help resynchronize the body's internal clocks. To finally test this hypothesis, researchers have developed a free mobile app that guides users through a 24-hour schedule of acupressure points. The article provides a concise overview of the science of circadian rhythms, which are regulated by the brain's suprachiasmatic nucleus (SCN) and can be influenced by external cues called zeitgebers. Citing recent studies, it establishes the neurobiological plausibility of acupuncture acting as a non-photic zeitgeber to modulate these rhythms. For practical accessibility during travel, the app substitutes some hard-to-reach foot points with alternative points on the same meridian, such as using GB 20 at the base of the skull for the Gallbladder channel. The authors invite readers to download the app, use it during their next international trip, and complete a follow-up survey to contribute valuable data to this important research.
