Akibat Kurang Tidur

Banyak orang menganggap kurang tidur merupakan hal biasa padahal menurut sebuah penelitian dari Universitas Pennsylvannia, kekurangan tidur sama berbahaya dengan tidak tidur.

Para peneliti menemukan orang yang tidur hanya empat sampai enam jam per malam bereaksi lebih lambat dibanding mereka yang tidur selama delapan jam. Kondisi ini juga sama pada mereka yang tidak tidur selama dua malam walaupun mereka mengatakan tidak merasa lelah padahal ini adalah awal dari sebuah masalah.

Menurut penelitian orang dewasa membutuhkan tidur selama delapan jam dalam satu hari. Jumlah ini akan bervariasi dari satu orang ke orang lain tergantung jumlah kegiatan yang dilakukan.

Penelitian yang dilakukan pada 48 orang dewasa sehat yang berumur 21 sampai 38 tahun, usia dimana paling dikaitkan dengan kekurangan tidur akibat tuntutan pekerjaan.

Kekurangan tidur mungkin tidak terlalu berpengaruh pada penampilan rutinitas sepanjang hari namun dapat memicu masalah fisik seperti:

Obesitas: Tidur memegang peranan dalam kemampuan tubuh untuk mengeluarkan neurohormon karena ketika jumlah pengeluaran hormon menurun, kesempatan bertambah berat badan meningkat.

Tekanan darah: Tekanan darah secara alami akan turun selama tidur. Namun akibat kekurangan tidur dapat memicu hipertensi dan masalah kardiovaskular.

Diabetes: Kemampuan tubuh menggunakan insulin dapat terganggu akibat kekurangan tidur sehingga memicu diabetes.

Menurut National Sleep Foundation dalam sebuah polling tahun 2002 di Amerika ditemukan sebanyak 47 juta orang dewasa tidak mendapatkan jumlah minimal tidur yang mereka butuhkan setiap malam.

Naah…jangan sepelekan istirahat ya..Mari kita coba atur porsi bekerja dan istirahat kita sebaik mungkin agar terhindar dari penyakit di kemudian hari.

  3. hi..Dry, The majority of Japanese seem to spend most of their life at work. A typical day is a 10AM start and a midnight finish.
    According to a recent survey however, it looks like the Japanese are working even more and sleeping much less.

    I’m usually up at an average of 6AM and try to turn in at midnight. Any less than 6 hours sleep means that I get sleepy after lunch. Sometimes I would get into the habit of sleeping even less but usually ends up with me getting sick.

    Whenever possible, I try to make time at night to tidy up my mind a little by going over what I did that day and plan for the next day. By doing that while I’m awake, I find that I sleep better and am guessing that it helps take some burden off the brain from processing these thoughts while I’m asleep? Have no idea but it seems to work.

    A friend of mine was saying that through his studies, humans should be able to get by with only 4 hours worth of sleep.
    I’ve also heard some people say that people who sleep less die at an early age. I find this statement interesting and wonder occasionally if the time allocated to us by fate is predetermined.

    If you knew that sleeping less (and getting more done while you are young) meant dying at an early age (lets say at 55 years)
    For those who find it a bit tough to wake up in the morning – you’ll need one of these. Once you have it, you wont need an alarm clock to get you out of bed. Its what drives me every day.

  4. If you can not sleep soundly and can’t totally focus in class,
    I hace some sleep tips for get sleep soundly.
    * Try visualization. Focus all your attention on your toes or visualize walking down an endless stairwell. Thinking about repetitive or mindless things will help your brain to shut down and adjust to sleep.
    * Get out of bed if unable to sleep. Don’t lie in bed awake. Go into another room and do something relaxing until you feel sleepy. Worrying about falling asleep actually keeps many people awake.
    * Don’t do anything stimulating. Don’t read anything job-related or watch a stimulating TV program (commercials and news shows tend to be alerting). Don’t expose yourself to bright light. The light gives cues to your brain that it is time to wake up.
    * Get up and eat some turkey. Turkey contains tryptophan, a major building block for making serotonin, a neurotransmitter, which sends messages between nerve cells and causes feelings of sleepiness. Note that L-tryptophan doesn’t act on the brain unless you eat it on an empty stomach with no protein present, so keep some turkey in the refrigerator for 3am.
    * Consider changing your bedtime. If you are experiencing sleeplessness or insomnia consistently, think about going to bed later so that the time you spend in bed is spent sleeping. If you are only getting five hours of sleep at night, figure out what time you need to get up and subtract five hours (for example, if you want to get up at 6:00 am, go to bed at 1:00 am). This may seem counterproductive and, at first, you may be depriving yourself of some sleep, but it can help train your body to sleep consistently while in bed. When you are spending all of your time in bed sleeping, you can gradually sleep more, by adding 15 minutes at a time.

    I hope this Tips can help you to get a good sleep !!!
