As a rule, your sleep during the night is divided into the following recurring phases:
Phase
Light sleep
Deep sleep
REM sleep
Impacts of lack of sleep
A lack of sleep can have a variety of physical and mental consequences. The impacts range from a lack of
concentration, reduced mental capability and irritability to personality disorders. If your natural sleep rhythm
is unsettled, human body functions such as breathing, blood pressure and metabolism can also be disrupt-
ed, weakening the immune system and accelerating the ageing process. Long-term studies have shown
that there is a link between cardiovascular disease and a sustained lack of sleep (regularly having less than
6 hours of sleep) or breathing disorders during sleep.

Description
Light sleep is divided into two phases. The first phase is very short
and only lasts just under 10 minutes. During this time the tension in
your muscles reduces and they begin to twitch. In the second phase
the muscles are relaxed. Light sleep accounts for around 50% of the
healthy sleeping time. The main difference between light sleep and
deep sleep is the number of stimuli required to wake the sleeping
person. It is significantly easier to wake a person from light sleep than
from deep sleep.
Breathing is now very even and the heart rate slows down. The mus-
cles are now fully relaxed. It is difficult to wake up the sleeper; they
are recovering from physical activity.
REM ("Rapid Eye Movement") sleep kicks in every 60–90 minutes:
Your eyes move rapidly, your brain is very active (you have many
dreams), your breathing becomes irregular and your muscles are par-
alysed.
