A food-based solution that tastes pleasant and requires no prescription
En un mundo donde el insomnio se ha convertido en una queja cotidiana de millones, la ciencia y la naturaleza parecen encontrarse en un pequeño fruto verde: el kiwi. El cardiólogo Aurelio Rojas propone que consumir uno o dos kiwis una hora antes de dormir puede reducir a la mitad el tiempo necesario para conciliar el sueño, gracias a su contenido en serotonina, el neurotransmisor que regula el descanso. En un momento en que muchos buscan alternativas a los fármacos, esta recomendación invita a reconsiderar el papel silencioso pero poderoso de la alimentación en nuestra salud más íntima.
- El insomnio afecta a una proporción creciente de la población, agravado por el estrés y el ritmo acelerado de la vida moderna que fragmenta el descanso nocturno.
- La dependencia de medicamentos para dormir genera preocupación entre quienes buscan soluciones sin efectos secundarios ni receta médica.
- El cardiólogo Aurelio Rojas afirma que comer uno o dos kiwis una hora antes de acostarse puede acelerar la conciliación del sueño hasta en un 50%, rivalizando con ciertos fármacos.
- El mecanismo propuesto apunta a la serotonina presente en el kiwi, que actuaría sobre la causa fisiológica del insomnio en lugar de enmascarar sus síntomas.
- La solución se perfila como accesible, económica y sin necesidad de supervisión médica, lo que aumenta su atractivo para quienes padecen insomnio leve o moderado.
El cardiólogo Aurelio Rojas, con notable presencia en redes sociales, ha puesto el foco en el kiwi como aliado natural del sueño. Su recomendación es concreta: tomar uno o dos kiwis aproximadamente una hora antes de acostarse podría reducir a la mitad el tiempo necesario para dormirse. La clave estaría en la serotonina, un neurotransmisor presente en la fruta que la investigación ha vinculado directamente con la calidad del sueño. Según Rojas, el efecto sería comparable al de algunos medicamentos para el insomnio, lo que lo convierte en una alternativa atractiva para quienes prefieren evitar intervenciones farmacológicas.
El insomnio es hoy un problema extendido, alimentado por el estrés y la sobreestimulación constante de la vida contemporánea. Aunque el ejercicio y los relajantes naturales son recursos habituales, el papel de la dieta en el descanso suele subestimarse. Lo que comemos en las horas previas al sueño puede influir de forma significativa en cómo y cuánto descansamos.
Más allá de la serotonina, el kiwi es un fruto nutricionalmente denso. Aporta fibra, vitamina E, vitamina K, folato, potasio y una cantidad destacada de vitamina C —el kiwi verde dobla la de la naranja o la fresa, y el amarillo la triplica—. La Fundación Española de Nutrición lo reconoce como fuente tanto de nutrientes como de sustancias bioactivas con valor documentado para la salud.
La propuesta de Rojas resulta especialmente atractiva por su sencillez: un alimento agradable, barato y sin necesidad de prescripción que, consumido en el momento adecuado, podría actuar sobre el mecanismo fisiológico del insomnio en lugar de limitarse a aliviar sus síntomas.
Aurelio Rojas, a cardiologist with a visible social media presence, has begun promoting kiwi as a natural sleep aid, claiming that eating one or two of the fruits an hour before bed can accelerate the onset of sleep by roughly half. The assertion rests on the fruit's serotonin content—a neurotransmitter that research has linked to sleep quality and the ability to fall asleep without difficulty. According to Rojas, the effect is substantial enough to rival certain pharmaceutical sleep medications, making it an appealing option for people struggling with insomnia who prefer to avoid chemical interventions.
Insomnia has become a widespread problem, driven in part by the stress, constant stimulation, and relentless pace of modern life. Many people find their sleep quality degraded and their ability to rest compromised by these pressures. While exercise, natural relaxants, and chemical sleep aids are common approaches, the role of diet in sleep quality is often underestimated. What we eat throughout the day—and particularly what we consume in the hours before sleep—can meaningfully influence how quickly and deeply we rest.
The kiwi's reputation as a sleep aid extends beyond its serotonin content. The fruit is nutrient-dense, containing moderate amounts of carbohydrates in the form of natural sugars, along with substantial fiber, primarily insoluble. Its vitamin C content is particularly notable: green kiwis contain roughly twice the vitamin C found in strawberries or oranges, while yellow kiwis contain approximately three times as much. The fruit also delivers significant quantities of vitamin E, vitamin K, folate, carotenoids, potassium, and various phytonutrients—compounds that provide both nutritional and health benefits beyond basic caloric intake.
According to the Spanish Nutrition Foundation, kiwis represent a source of both nutrients and non-nutritive bioactive substances with documented health value. The combination of these elements makes the fruit more than a simple carbohydrate delivery system; it functions as a concentrated package of compounds that support bodily function across multiple systems. For those seeking to improve sleep without pharmaceutical intervention, the fruit offers a straightforward, accessible alternative that can be incorporated into an evening routine with minimal effort or cost.
Rojas's recommendation is simple and specific: consume one or two kiwis approximately sixty minutes before bed. This timing appears to matter, as the window between consumption and sleep onset seems to be when the fruit's serotonin and other compounds exert their effect. For people whose insomnia stems from low serotonin levels—a documented physiological cause of sleep difficulty—this approach addresses the underlying mechanism rather than merely masking symptoms. The appeal is clear: a food-based solution that tastes pleasant, costs little, and requires no prescription or medical supervision.

Why would a cardiologist be the one promoting a sleep remedy? That seems like an odd fit.
Cardiologists understand the cardiovascular system's relationship to sleep quality—poor sleep raises blood pressure and stress hormones. For Rojas, it's probably not a stretch from his specialty; it's an extension of it.
The claim is that kiwis work 50% faster. That's a very specific number. Where does it come from?
He's citing research, though the source material doesn't specify which studies. The precision of the number suggests there's actual data behind it, but the claim would need independent verification.
Is serotonin actually present in kiwis in meaningful amounts?
Yes—kiwis do contain serotonin, which is unusual for a fruit. Whether the amount you consume orally translates to measurable brain serotonin is a different question, but the compound is there.
So this could be placebo, or it could be real.
It could be either. The mechanism is plausible—serotonin does affect sleep—but the 50% figure and the equivalence to medications are claims that deserve scrutiny.
Why is he promoting this on TikTok and Instagram rather than publishing in a medical journal?
Social media reaches more people faster and requires no peer review. It's effective marketing, though it also means the claims bypass the gatekeeping that would normally apply to medical assertions.
