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

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

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