Which hormone naturally present in certain grapes regulates the sleep-wake cycle?
Answer
Melatonin
Grapes offer an unexpected benefit related to rest and recovery because certain varieties naturally contain melatonin. Melatonin is the essential hormone responsible for governing the body’s internal sleep-wake cycle, also known as the circadian rhythm. Consuming grapes, particularly in the evening, provides a small, natural source of this hormone. This offers a gentle method to support the body’s own production of melatonin, signaling the appropriate time for the body to transition into a resting state, acting as a soft cue for rest compared to higher-dose supplemental forms.
