Cuanto más tiempo pasamos despiertos, más lentos somos

Un estudio realizado por científicos del Hospital Brigham y de Mujeres (BWH) de Boston revela que la falta de sueño nos vuelve más lentos, incluso si no nos sentimos físicamente cansados. Concretamente, según explican la neurocientífica Jeanne F. Duffy y sus colegas en el último número de la revista The Journal of Vision, dormir solamente entre cinco y seis horas cada noche puede afectar negativamente al desempeño tareas visuales complejas implicadas en trabajos como el control de tráfico aéreo o la revisión de equipajes de pasajeros en estaciones de tren y aeropuertos. «Este tipo de trabajos exige codificar datos en la memoria, procesar abundante información visual y tomar decisiones constantemente a partir de la información, todo ello de manera rápida y repetida», aclaran los investigadores. En sus experimentos demostraron que cuantas más horas pasamos despiertos más lentos somos desempeñando este tipo de actividades. Por otro lado, cuando dormimos poco, a medida que transcurren las horas de vigilia nos cuesta más identificar qué parte de la información que percibimos es relevante. Y a esto se suma que durante la noche el «exceso de lentitud» se agrava, según concluyen los científicos.

  3. I agree that it’s pretty tacky to use them on planes. It’s not just your peace of mind, but everyone’s peace of mind that you have to be concerned with. Even if you approach it correctly, it still looks too much like a regular cigarette in most cases for the people around you. It’s all about well-being, yours and everyone else’s, not about getting around a smoking ban.
