Stenberg: La gente se rió y dijo que la investigación del sueño no tenía sentido y era asquerosa

Cuando la conversadora de verano de Las Vegas, Tarja Stenberg, comenzó su carrera como investigadora del cerebro y del sueño hace 40 años, muchos se rieron. ¿Qué había para investigar sobre algo tan sin sentido como dormir?

 

 

Han pasado más de 40 años desde que Tarja Stenberg comenzó su carrera como investigadora y profesora en la Universidad de Helsinki.

- Cuando comencé a investigar el sueño, muchos investigadores pensaron que podría haber una razón válida para estudiar el cerebro, pero dormir: ¡fue realmente ridículo!

Pero como investigadora, Tarja Stenberg siempre ha tenido una fuerte convicción: dormir es importante para el cerebro.

- Muchos colegas sonrieron cortésmente cuando les dije que estaba estudiando dormir. Entonces generalmente era la única mujer en la habitación. Algunos colegas se rieron a carcajadas cuando presenté mis ideas sobre las moléculas que inducen el sueño.

También se decía que el cerebro era demasiado complicado para ser estudiado con métodos científicos. También hubo una fuerte reticencia a estudiar el cerebro.

- Se consideró perjudicial para la moral aprender sobre el cerebro, que es lo más sagrado en fisiología humana. El cerebro y la moralidad fueron los que nos hicieron humanos y nos separaron de los animales.

La idea de que hemos evolucionado a partir de animales era bastante desagradable.

- Era simplemente impensable que nuestros buenos pensamientos y sentimientos pudieran ser medidos y analizados.

¿Podría la privación del sueño realmente causar enfermedades graves?

Desde entonces, Stenberg ha estado interesado en la importancia del sueño, especialmente la falta de sueño. Ella menciona especialmente un momento memorable.

- Hace veinte años, recibimos los primeros informes emocionantes de la investigadora Eve van Cauter en Chicago sobre cómo la falta de sueño puede alterar nuestro equilibrio de azúcar y resistencia a la insulina.

Van Cauter realizó un experimento en el que hombres jóvenes y sanos durante cinco días acortaron su sueño a cuatro horas por noche. El descubrimiento sorprendió a Stenberg. Los niveles de insulina en los sujetos de prueba aumentaron.

- Me costaba creer lo que escuchaba, porque la falta de sueño hasta ese momento siempre se había minimizado.

Entonces se pensó que el que menos duerme es un superhumano, el más fuerte y el más sabio.

- Los líderes empresariales exitosos, los políticos y otros se jactaban de lo poco que dormían.

¡Como si fuera algo bueno!

- Muchas personas tuvieron dificultades para creer que algo tan modesto como la falta de sueño podría causar trastornos tan graves en el cuerpo. Durante mi carrera, las actitudes han cambiado y la importancia del sueño se ha tomado más en serio.
Todo el cuerpo se ve afectado cuando dormimos un poco

Más tarde, también se descubrió que la obesidad ocurre con mayor frecuencia en personas que duermen poco, pero también en diabetes tipo 2. y enfermedades cardiovasculares. La enfermedad de Alzheimer y la depresión también están relacionadas con la falta de sueño.

- Como investigador del sueño, a menudo me pregunto "¿Qué pasa si no dormimos lo suficiente?". Creo que todos sabemos lo que está pasando. Nos cansamos, molestamos e incomodamos.

Esto se debe a que la plasticidad del cerebro disminuye, se hace más difícil aprender cosas nuevas, concentrarse y más difícil de recordar. También se vuelve mucho más difícil motivarse para comenzar nuevas tareas.

- La capacidad de resolución de problemas también se deteriora. Se están repitiendo las soluciones antiguas, aunque ya se ha visto que el método anterior no funciona.

El sueño afecta a todo el cuerpo.

Tarja Stenberg habla en el verano sobre lo que sucede en nuestros cerebros cuando nos acostamos por la noche, o cómo nos afecta cuando ignoramos hacerlo.

El programa de entrevistas de verano de Las Vegas se transmite todos los días laborables en 10:03 y 22:15. Puedes escuchar la Arena en cualquier momento.

Without any notice, a 56-year-old actor with no ass- kicking on experience singlehandedly saved action videos.
