    Have you ever felt that you've been hit on the head after a bad nights sleep？A study shows that if you don't sleep for just one night，it may cause changes in the brain just like you are hit on the head .
    Professor Benedict，from Sweden，said. "We found that their blood pressure（血壓） rose if they didn't sleep for a night.He said the finding showed how the brain relaxes itself by sleeping.Professor Benedict，whose study was published in the Journal Sleep，added， "As a result，a good night's sleep may be important for keeping our brain health."
    Compared with the people who lived 30 years ago，most people now sleep for only seven hours night.So a third of the population in the UK suffers from sleep-related（相關(guān)的） problems.Many scientists believe irregular（不規(guī)律的）sleeping habits can cause heart disease，and less than eight hours sleep night can lower the IQ the next day.
    As a middle school student，I know there are many reasons for our loss of sleep，mostly connected with the pressure of success.For example，we have spend much time on our homework and other study tasks from teachers or parents .A long- term loss of sleep will make us tired and depressed（情緒低落的）.Even worse，it will make some students develop a dangerous behavior of smoking.
    Luckily，some effective actions have been taken to make sure that students have enough sleep.So I think families，schools and the government should take efforts to make students get more sleep.
