Purpose: This study was done to investigate quality of sleep and heart rate variability by the physical activity in high school students. Methods: A survey that measures physical activity and quality of sleep was distributed to 118 students at Y High School. Heart rate variability was obtained using...

수면 시간 부족이 청소년에게 미치는 영향은? | 신체활동과 더불어 수면은 청소년 건강을 위한 또 다른 중요한 요소로 수면 시간 부족과 수면의 질 저하는 기억력 감소, 집중력 저하 등 학생들의 인지 기능에 영향을 미치며 학습에 부정적인 영향을 초래한다[1]. 수면 시간이 충분하지 않다고 느낄 때 학생들은 건강하지 않다고 인식하였으며[10], 수면 시간이 6시간 미만인 학생은 행복도가 낮은 것으로 나타났다[11]. 반면, 수면 시간이 8시간 이상인 청소년 집단에서 행복도는 높게, 스트레스 인지율, 우울 및 자살에 대한 생각은 낮게 나타났다[2]. | |
청소년기란? | 청소년기는 신체적, 정신적으로 성장속도가 빠르며, 외적 자극 또는 환경에 민감한 시기이기 때문에 건강을 유지하기 위해서는 꾸준한 운동이 필요하며, 정서적 안정, 성장, 학습 등을 위해 충분한 수면이 권장 된다[1,2]. 특히 체내 항상성 유지라는 중요한 역할을 담당하고 있는 자율신경계는 스트레스와 같은 내, 외부 자극에 민감하며 이상 시 여러 가지 문제를 야기할 수 있다. | |
신체활동이 청소년기에 중요한 이유는? | 신체활동은 걷기, 달리기, 줄넘기 등 골격근 수축으로 인해 발생하는 움직임으로 일정한 수준의 신체활동은 비만, 고혈압, 당뇨 등 만성질환을 예방하는 역할을 하므로 건강습관을 형성하는 청소년기에 매우 중요하다[5]. 꾸준한 신체활동은 긍정적인 신체적 자기개념을 형성 하게 하며, 자살, 우울 등 부정적인 생각을 감소시키며[4,6], 신체활동 참여 시간이 증가할수록 남학생의 혈압, 중성지방, 인슐린 수치가 감소 하는 것으로 나타났다[7]. |
