CHAPTER
XIX:
Suggestions
About
Sleep
Sleep
is
one
of
the
first
essentials
in
maintaining
or
in
building
vitality.
There
are
differences
of
opinion
as
to
how
much
sleep
may
be
necessary
to
health,
but
that
sufficient
sleep
is
required
if
one
wishes
to
maintain
the
maximum
of
energy
no
one
can
question.
Sleep
is
far
more
necessary
than
food.
One
can
fast
for
many
days,
or
many
weeks
if
necessary,
and
without
any
special
disadvantage
if
he
is
well
nourished
before
beginning
the
fast
and
has
a
satisfactory
food
supply
after
ifs
conclusion,
but
no
one
can
"fast"
from
sleep
for
more
than
a
few
days
at
a
time
without
experiencing
ill
effects.
One
can
scarcely
endure
an
entire
week
of
absolute
sleeplessness.
It
has
been
found
that
dogs
kept
awake
even
though
sufficiently
fed,
suffer
more
than
when
deprived
of
food
and
permitted
to
sleep.
When
kept
awake
continuously
they
die
in
four
or
five
days.
Man
can
endure
the
strain
a
little
longer
than
the
dogs,
but
five
or
six
days
usually
marks
the
limit
of
human
life
under
such
conditions.
In
early
English
history
condemned
criminals
were
put
to
death
by
being
deprived
of
sleep,
and
the
same
method
has
been
employed
in
China.
Enforced
sleeplessness,
in
fact,
has
been
used
as
a
form
of
torture
by
the
Chinese,
being
more
feared
than
any
other.
The
men
subjected
to
this
frightful
ordeal
always
die
raving
maniacs.
These
facts
illustrate
only
too
well
the
imperative
necessity
for
sleep.
Unfortunately
"late
hours"
prevail,
especially
in
large
cities.
Manifestly,
if
complete
lack
of
sleep
is
fatal,
late
hours
and
partial
lack
of
sleep
is
at
least
devitalizing
and
detrimental
to
health.
The
late
hours
kept
by
large
numbers
of
people
in
civilized
countries
undoubtedly
contribute
very
largely
to
neurasthenia
and
allied
diseases.
Improvements
in
artificial
lights
have
contributed
largely
toward
the
increase
of
the
evil
of
late
hours,
injurious
not
only
through
the
loss
of
sleep
entailed,
but
also
because
of
the
eye-strain
incidental
to
strong
artificial
lights
and
the
drain
on
the
nervous
system.
If
civilized
man
would
follow
the
example
of
primitive
man
and
of
many
of
the
birds
and
animals
in
retiring
to
bed
with
the
coming
of
darkness
and
arising
with
the
appearance
of
daylight,
this
one
change
would
revolutionize
the
health
of
the
whole
human
race.
