Hvorfor du våkner like før vekkerklokka

Geir Werner Hagen

Jeg våkner som regel tidlig, og veldig ofte våkner jeg og slår av alarmen rett før den setter i gang. Grunnen er at kroppen vår er like nøyaktig som ei vekkerklokke. Kroppen din skjønner når du vil våkne og gjør det. Vekker deg til rett tid.

There's evidence you can will yourself to wake on time, too. Sleep scientists at Germany's University of Lubeck asked 15 volunteers to sleep in their lab for three nights. One night, the group was told they'd be woken at 6 a.m., while on other nights the group was told they'd be woken at 9 a.m..

But the researchers lied-they woke the volunteers at 6 a.m anyway. And the results were startling. The days when sleepers were told they'd wake up early, their stress hormones increased at 4:30 a.m., as if they were anticipating an early morning. When the sleepers were told they'd wake up at 9 a.m., their stress hormones didn't increase -- and they woke up groggier. "Our bodies, in other words, note the time we hope to begin our day and gradually prepare us for consciousness," writes Jeff Howe at Psychology Today.
