A
new
study
reports
that
lack
of
deep
sleep
contributes
to
the
aging
of
males.
Sleep,
which
affects
the
regulation
of
growth
hormone
and
cortisol
secretion
in
young
adults,
decreases
in
duration
and
diminishes
in
quality
with
normal
aging.

Journal
of
the
American
Medical
Association)
In
this
cross-sectional
study
of
149
healthy
men
aged
16
to
83
years,
Van
Cauter
and
colleagues
found
that
from
early
to
mid-adulthood,
deep
slow
wave
sleep
and
growth
hormone
secretion
decreased
markedly,
but
total
sleep,
sleep
fragmentation,
REM
sleep,
and
cortisol
secretion
did
not
change.
From
midlife
to
late
life,
REM
sleep
decreased,
wake
time
increased,
and
nocturnal
cortisol
release
increased.
In
an
editorial,
Blackman
reviews
the
effects
of
aging
on
sleep
regulation,
age-related
changes
in
neuroendocrine
function,
and
their
interrelationship.
