[고1] 2025 09월 – 32번: 수면 부족을 감지하고 수면을 유도하는 아데노신(adenosine)의 역할

 

Although you may put off going to sleep in order to squeeze more activities into your day, eventually your need for sleep becomes overwhelming and you are forced to get some sleep. This daily drive for sleep appears to be due, in part, to a compound known as adenosine. This natural chemical builds up in your blood as time awake increases. While you sleep, your body breaks down the adenosine. Thus, this molecule may be what your body uses to keep track of lost sleep and to trigger sleep when needed. An accumulation of adenosine and other factors might explain why, after several nights of less than optimal amounts of sleep, you build up a sleep debt that you must make up by sleeping longer than normal. Because of such built-in molecular feedback, you can't become accustomed to getting less sleep than your body needs. Eventually, a lack of sleep catches up with you.

구분	내용	원문
주장	잠을 미루더라도 결국 수면 욕구가 쌓여 잠을 자게 된다	Although you may put off going to sleep in order to squeeze more activities into your day, eventually your need for sleep becomes overwhelming and you are forced to get some sleep.
근거	수면 욕구는 아데노신이라는 화합물 때문인데, 깨어 있는 동안 혈액 속에 쌓이고, 수면 중에 분해된다	This daily drive for sleep appears to be due, in part, to a compound known as adenosine. This natural chemical builds up in your blood as time awake increases. While you sleep, your body breaks down the adenosine.
설명	아데노신은 잃은 수면을 기록하고 필요한 때 수면을 유도하는 역할을 한다	Thus, this molecule may be what your body uses to keep track of lost sleep and to trigger sleep when needed.
근거	아데노신 축적과 다른 요인으로 인해 수면 부족이 누적되면 ‘수면 부채’가 쌓여 보충 수면이 필요하다	An accumulation of adenosine and other factors might explain why, after several nights of less than optimal amounts of sleep, you build up a sleep debt that you must make up by sleeping longer than normal.
결론	이런 분자적 피드백 때문에 필요한 수면량보다 적게 자는 생활에 익숙해질 수 없고, 결국 수면 부족이 쌓인다	Because of such built-in molecular feedback, you can't become accustomed to getting less sleep than your body needs. Eventually, a lack of sleep catches up with you.
