actually wise medical advice. The body can
”sleep itself well“. During sleep, blood pressure
is also lowered and the heart beats more
slowly. Each time you wake at night, the blood
pressure rises again. High blood pressure, cardiac
arrhythmias and cardiovascular diseases
may develop because of this. Those who sleep
well also prevent burnout and depression, as
messenger substances released during sleep
break down the stress hormone cortisol.

BECOME AN EINSTEIN
Anyone who sleeps after studying
remembers newly acquired knowledge
particularly well. In deep sleep, the brain can
optimally store new knowledge. If, for example,
we learn great new marketing terms and
strategies in a training course, we absorb the
knowledge while we are awake. But we only
remember it in sleep. During the day, the brain
saves the new information in a kind of cache.
But only in sleep does it transfer the essentials
into long-term memory.

SEND SIEGMUND FREUD ON
VACATION
After deep sleep, the REM phase (Rapid Eye
Movement) begins. Here, brain activity, breathing,
pulse and blood pressure become almost
as active again as in the waking state. However,
the muscles remain completely relaxed.
Researchers at the University of California at
Berkeley have observed that during the dream
phase, the production of norepinephrine in the
brain decreases sharply. It is a neurotransmitter
that occurs during stress. In dream sleep,
the brain suppresses the release of this stress
hormone. In this way, memories of the day
can be classified and saved without triggering
stress or storing this stress.
This important dream phase during sleep
works like a kind of overnight therapy, in which
the emotional experiences of the day are
processed and the associated impressions of
stress are alleviated. (ts,mb)
