healthy sleep

in peoples life, one third of the time is spent in sleep. without

normal

sleep, we cannot sustain other life activities. sleep can refresh

our minds and improve memory ability. ensuring adequate

sleep time and sleeping efficiently is vital for learning and

working.

we sleep every day, but rarely think deeply about it. sleep can

be divided into two periods: rapid-eye-movement sleep (rem

sleep) and non-rapid eye movement sleep (non-rem sleep). the

former can protect the brain, relieve emotions and restore

energy, while the latter can eliminate fatigue, restore physical

strength, enhance immunity, recovery body capacity and

promote growth and development.

what sleep can bring us? perhaps the answer is not very clear.

however, if we put this question in turn, what if we do not sleep

well, then the answer can be surprisingly obvious, or maybe

not obvious but surprising.

today, people are faced with a variety of pressures in life.

students must complete their studies; workers have to

complete their work, so sometimes people have to stay up late.

all these can take up sleep time. the results do harm to our

health severely and may even threat the safety of others.

studies show that lack of sleep can damage our attention,

alertness,

concentration of mind, reasoning and problem- solving

abilities, which easily lead to injuries and accidents.

furthermore, sleep debt can increase the risk of

1210010210

many diseases. for instance, among insomniacs, the

morbidity of heart

disease, hypertension, stroke, diabetes and etc. is higher than

normal people. in addition, lack of sleep and sleep disorders

can also lead to depression, cutis laxa(the skin relaxation) and

pachulosis(rough skin). interestingly, lack of sleep can

enhance peoples sense of hunger. data show that people sleep

less than five hours a day are more closely related with obesity

even the risk of death. and both american and chinese official

data show that fatigue driving caused by sleep deprivation has

been a global road safety problem. unfortunately, the fact is

different with a lot of peoples misunderstanding that a few

hours of sleep after staying up late cannot make up actually.

in many cases, sleep deprivation is caused by our subjective

wills.

however, there are many objectively pathological changes can

make us

sleepless or persistent sleepy. in physiological aspects , it can

be caused by abuse of drugs, alcohol and other substance,

periodic leg movement(

周期性腿动

< p>)

，

restless legs syndrome(

不

宁腿综合症

), cerebral degeneration(

脑退化性病变

)

，

hyperthyroidism

（甲亢），

clim acteric syndrome

（更年期综合

症）

and other somatic diseases. in psychological aspect, it will

easily develop when people experience great mood fluctuation,

such as excitement, grief or fear. under normal circumstances,

sleep deprivation will self-cure in few days or weeks. if it not,

please pay more attention on that, because long term sleep

debt can lead to anxiety, depression and chronic insomnia.

now scientists believe that it

1210010210

is caused by the unbalance of neurotransmitter release(

递质释

放

) and neurons regulate

（神经元调节），

while the accurate

cause of sleep deprivation is still a mystery. in consideration

of the theory is quite complex, it seems wise to obey the

biothythm(

生物节律

) which formed in long evolution of human

biological clock.

so, how can we have a healthy sleep? here are a few

suggestions.

firstly, we should decide sleep time according to our own

situation.

everybody have different need of the quantity of sleep. it is

depended on our different health condition, nutritional status

and labor intensity. of course,

some people can live pretty well without regular life, but if that

make your body occur disorders, please understand that is not

suit for you.

mean the quieter the better, some light music is really helpful.

when it comes to the illumination, the darker the better is in

point. because light will reduce the secretion of melatonin(

< p>褪黑

素

)

，

which can promote sleep during night. so, keeping

curtains totally closed and turning off all lights are useful tips

to have a good sleep.

then, bear this in minds, don’t drink coffee, wine and food not

easy to

digest before bedtime as well as don’t eat too much in dinn

er.

coffee contains

1210010210

cocaine, which makes us nerves excitement. bedtime drink

probably can

accelerate sleep, but it will damage the quality of sleep. for

food hard to digest, such as sweet potatoes and corns, should

be avoided at bedtime. however, fish and milk that contains

calcium(

钙

) and magnesium

（镁）

, can relieve

emotion and help sleep. therefore, to arrange dinner in

reasonable amount is significant.

last but not least, proper activities should be seriously valued.

do not take strenuous exercise in four hours before bedtime.

meanwhile it is effective to do some training for abdominal

breath(

腹式呼吸训练

) and meditation(

冥想

) under the guidance

of a doctor.

in conclusion, we live in a society fulfilled with pressures and

difficulty. it is not easy to sleep without any worry, when

almost everyone tries so hard to expand the width of life by

staying up late. then, how about the length of life? how about

the quality of life? do you really think career success is more

valuable than happy family time and healthy life?

moreover, life is long, what you want desperately time will

give to you

some day. so don’t be so impatient, before we devote

ourselves to do

something big, let we learn how to have a healthy sleep first.
