We've confused discipline with biology, treating them as if they were the same thing.
En una cultura que ha convertido el madrugador en símbolo de virtud, el psicólogo del sueño Günther Amann-Jennson ofrece una corrección necesaria: el cuerpo humano no es uniforme, y forzarlo a seguir un horario ajeno a su biología no produce disciplina, sino agotamiento. Su argumento no es una invitación a la pereza, sino un llamado a distinguir entre lo que la cultura celebra y lo que la ciencia sostiene. En un mundo donde el noventa y cinco por ciento de las personas duerme menos de lo que necesita, la pregunta no es a qué hora suena el despertador, sino si el cuerpo ha tenido la oportunidad real de descansar.
- El despertador a las cinco de la mañana se ha convertido en un ícono cultural, pero para la mayoría de las personas representa una batalla diaria contra su propia biología.
- Cerca del treinta por ciento de la población son noctámbulos por naturaleza: su mente no alcanza su pico hasta la tarde, y obligarlos a madrugar equivale a pedirle a un zurdo que escriba con la mano derecha.
- La ciencia del sueño señala que lo que ocurre antes de dormir —oscuridad, silencio, temperatura fresca y una cena temprana— importa más que la hora en que suena la alarma.
- El verdadero riesgo no es quedarse dormido, sino seguir confundiendo el cronotipo con el carácter: tratar la biología como si fuera una falla moral.
El despertador a las cinco de la mañana se ha convertido en un monumento cultural a la disciplina. Levantarse temprano, ir al gimnasio, desayunar, llegar al trabajo antes que nadie: la rutina suena virtuosa, casi noble. Pero el psicólogo del sueño Günther Amann-Jennson sostiene que todo ese edificio descansa sobre un malentendido profundo sobre cómo funciona el cuerpo humano.
Según Amann-Jennson, el noventa y cinco por ciento de las personas —desde niños pequeños hasta adultos mayores— duerme crónicamente menos de lo que necesita. El problema no es la pereza ni la falta de voluntad. Es que hemos construido una cultura sobre la suposición de que madrugar genera disciplina, y que la disciplina produce éxito. Lo que se pierde en esa ecuación es la biología misma.
La realidad es más matizada. Algunas personas son genuinamente madrugadoras: despiertan con energía y la mente despejada. Para ellas, levantarse temprano funciona, siempre que también se acuesten a tiempo para completar las siete a nueve horas que el cuerpo necesita. Pero alrededor del treinta por ciento de la población son noctámbulos. No alcanzan su mejor rendimiento mental hasta la tarde. Para estas personas, forzar un despertar a las cinco de la mañana no es disciplina: es combatir su propia neurología.
Lo que más importa, argumenta Amann-Jennson, no es el reloj en la pared sino las condiciones que permiten un buen descanso: oscuridad, silencio, una temperatura fresca en la habitación y cenar con suficiente antelación para que la digestión no interfiera con el sueño. Nada glamoroso, nada que inspire una publicación en redes sociales. Pero sí lo que el cuerpo realmente necesita.
El mensaje de fondo es una invitación a escuchar los propios límites en lugar de conformarse con la plantilla de otro. La variable no es moral: es biológica. Y seguir insistiendo en que todos deben despertar al amanecer, sin importar su cronotipo, es precisamente lo que mantiene a la mayoría de las personas agotadas.
The alarm clock at five in the morning has become a cultural monument to discipline. Wake early, hit the gym, eat breakfast, get to work—the routine sounds virtuous, almost noble. But Günther Amann-Jennson, a sleep psychologist, sees it differently. He argues that this entire framework rests on a misunderstanding of how human bodies actually work.
According to Amann-Jennson, ninety-five percent of people—from small children to older adults—are chronically undersleeping. The problem isn't laziness or lack of willpower. It's that we've built a culture around the assumption that waking early creates discipline, and that discipline automatically produces success. What gets lost in that equation is biology itself. We've confused one with the other, treating them as if they were the same thing.
The reality, he explains, is more textured. Some people genuinely are morning people. They wake hungry, their minds sharp, their energy high. For them, early rising can work—provided they also go to bed early enough to get the seven to nine hours of sleep their bodies need. But roughly thirty percent of the population are night owls. They don't hit their mental stride until afternoon. Their peak performance comes when the sun is already descending. For these people, forcing a five-a.m. wake time isn't discipline. It's fighting against their own neurology.
Most people fall somewhere in between, neither strongly morning-oriented nor deeply nocturnal. And for this majority, the early-rising prescription doesn't fit. Amann-Jennson's point is straightforward: a schedule that works for one person's body may actively harm another's. The cultural insistence on universal early rising ignores this basic fact.
What matters more than the clock on the wall, he argues, is what happens before sleep arrives. The psychologist identifies four conditions that actually shape sleep quality: darkness, silence, a cool room temperature, and finishing dinner with enough time for digestion before bed. These aren't glamorous. They won't make for an inspiring Instagram post. But they're what your body actually needs to rest well.
The deeper message is about listening to your own limits rather than conforming to someone else's template. Before worrying about what time you wake, prioritize what allows you to sleep. For some, that means an early bedtime and early rise. For others, it means protecting afternoon and evening hours for their best work, then sleeping later. The variable isn't moral. It's biological. And pretending otherwise—insisting that everyone should rise at dawn regardless of their chronotype—is what's keeping most people exhausted.
Citas Notables
The entire early-rising movement is built on the assumption that waking early creates discipline, and that discipline automatically leads to success—but this confuses discipline with biology.— Günther Amann-Jennson, sleep psychologist
Night owls reach their peak mental performance in the afternoon, not the morning, making early rising incompatible with their biological rhythm.— Günther Amann-Jennson
La Conversación del Hearth Otra perspectiva de la historia
So when Amann-Jennson says ninety-five percent of people are undersleeping, is he saying they're not getting enough hours, or that their sleep is poor quality?
Both, really. He's pointing out that most people are fighting against their natural rhythm and also not getting adequate duration. The two problems feed each other.
But doesn't early rising work for some people? Why would it be so popular if it didn't deliver results for anyone?
It works brilliantly for the people whose bodies are wired that way—maybe twenty or thirty percent of the population. They become the visible success stories. Everyone else sees that and assumes it's the method itself that's powerful, not that it happened to match those people's biology.
So the real issue is that we've made a virtue out of something that's just... circumstantial?
Exactly. We've turned a chronotype into a character trait. Early rising became synonymous with discipline and success, when really it's just one valid schedule among several.
What about people who have no choice—whose jobs demand they show up at seven a.m.?
That's the hard part. Amann-Jennson isn't saying ignore your obligations. He's saying if you're forced into a schedule that doesn't match your body, you need to be even more intentional about the conditions that support sleep—the darkness, the quiet, the temperature, the meal timing. You're already working against yourself. Don't make it worse.
So the four conditions he mentions—those are non-negotiable?
They're the foundation. Everything else is secondary to that. You can't willpower your way past a room that's too warm or too bright.
