Garrrrrr!
Just remember that i haven
Do my coursework!><.
Next week pass up.
Dont feel like doing.hahaha.
But i have to =/.
Then give it a best try then!=).
Later doing project.
Maybe after that play
Left 4 dead ><.hahaha.
Long time didnt play lerhh.
Then after playing must
Faster do homework.ahhh!><.
Can someone invent a machine or
Robot that can do homework?
Then no need do homework!=DDD.
Or even a machine that can be your
Brain helps you to remember things
& study for you!
Then we all no need study lerhh!=P.
That will be the greatest invention =).
LOL!i know i dreaming ><.
Actually i am.hahaha xD!
Exams coming in 4 weeks time!
Got alot things haven study &
Revise..school stuffs,cca have
Alot of things,activitys to do!
Stress up sia..
How i wish i got all the
Time to study..
Maybe can use the sleeping time ><.
I should ask,WHY WE NEED TO SLEEP!
If humans no need sleep then
I got all the time to study =/..
Then no need so stress up =(.
Scare i cant pass this,pass that..
Done a research.
I guess quite long ><.
But for those who always sleeps
Late or never sleep at all,
Mybe you should read &
Understand the importence of sleep ><.
As the field of sleep research is still relatively new,
Scientists have yet to determine exactly why people sleep.
However, they do know that humans must sleep and,
In fact, people can survive longer without food
Than without sleep. And people are not alone
In this need -all mammals,reptiles and birds sleep.
Scientists have proposed the
Following theories on why humans require sleep:
-Sleep may be a way of recharging the brain.
The brain has a chance to shut down
And repair neurons and to exercise
Important neuronal connections that might
Otherwise deteriorate due to lack of activity.
-Sleep gives the brain an opportunity to
Reorganize data to help find a solution
To problem, process newly learned information
And organize and archive memories.
-Sleep lowers a person’s metabolic
Rate and energy consumption.
-The cardiovascular system also gets
A break during sleep. Researchers have found
That people with normal or high blood pressure
Experience a 20 to 30% reduction in blood
Pressure and 10 to 20% reduction in heart rate.
-During sleep, the body has a chance to replace
Chemicals and repair muscles,
Other tissues and aging or dead cells.
In children and young adults,
Growth hormones are released during deep sleep.
-When a person falls asleep and wakes up
Is largely determined by his or her
Circadian rhythm, a day-night cycle of about 24 hours.
Circadian rhythms greatly influence
The timing, amount and quality of sleep.
For many small mammals such as rodents,
Sleep has other particular benefits,
As it provides the only real opportunity for physical rest,
And confines the animal to the thermal insulation of a nest.
In these respects sleep conserves much
Energy in such mammals, particularly as sleep
Can also develop into a torpor,
Whereby metabolic rate drops significantly
For a few hours during the sleep period.
On the other hand, humans can usually rest and
Relax quite adequately during wakefulness,
And there is only a modest further energy saving
To be gained by sleeping. We do not enter torpor,
And the fall in metabolic rate for a human adult sleeping
Rather lying resting but awake, is only about 5-10%.
More than 20% of Americans are shift workers
Who work and sleep against their bodies’
Natural sleep-wake cycle. While a person’s
Circadian rhythm can not be ignored or reprogrammed,
The cycle can be altered by the timing of things such
As naps, exercise, bedtime, travel to a different
Time zone and exposure to light.
The more stable and consistent the cycle is,
The better the person sleeps. Disruption of circadian rhythms
Has even been found to cause mania in people with bipolar disorder.
Garrrrrr!it seems sleeps not only apply to us humans,
Even mammals,reptiles & birds sleep.
& it is importent to sleep..
So,i think i cant use my sleep time to study.
Ahhhhh!the only way should be find time
From the busy schedule ><.
Hope i can cope,& make it for my CA!xD.
