Tidur Tepat Waktu Tiap Malam Pertanda Orang Sukses? Hasil penelitian baru menunjukkan orang yang tidur pada waktu yang sama setiap malam jauh lebih sehat dan sukses daripada rekan mereka yang tidur secara spontan.
Sementara perkembangan penelitian tidur yang semakin meningkat cenderung berfokus pada jumlah waktu yang kita tidur, para ilmuwan di Rumah Sakit Brigham dan Wanita telah menemukan rutinitas sama pentingnya.
Sebuah tim mengukur ritme tidur pada 61 mahasiswa di Harvard College selama 30 hari dengan menggunakan buku harian tidur, kemudian membandingkan data tersebut dengan kinerja akademis mereka.
Secara luar biasa, siswa dengan pola tidur dan begadang yang tidak teratur memiliki nilai rata-rata lebih rendah daripada yang lain.
Mereka juga cenderung tidur sejenak lebih sering, daripada tidak tidur, dan berjuang mengantuk, karena melatonin yang tidak teratur, sebuah hormon yang membuat kita ingin tidur.
Penelitian ini merupakan salah satu studi pertama yang mempertimbangkan atau mengukur secara akurat efek pola tidur biasa.
Ini menunjukkan bahwa rutinitas yang tidak konsisten mencegah tubuh melepaskan hormon pada saat yang tepat untuk membuat kamu merasa mengantuk dan terjaga, sehingga melepaskan ritme sirkadian (jam tubuh).
Dalam studi tersebut, para peneliti mengukur keteraturan tidur menggunakan indeks keteraturan tidur (SRI), sebuah metrik yang baru dirancang.
Mereka meneliti hubungan antara SRI, durasi tidur, distribusi tidur sepanjang hari, dan prestasi akademik selama satu semester.
"Hasil penelitian kami menunjukkan bahwa tidur dan bangun pada waktu yang hampir bersamaan sama pentingnya dengan jumlah jam tidur seseorang," kata Dr Andrew JK Phillips, seorang biofisik di Divisi Gangguan Tidur dan Sirkular dilansir dari Daily News.
'Tidur secara tertatur adalah faktor yang berpotensi penting dan dapat dimodifikasi yang terlepas dari durasi tidur,' kata Dr Phillips.
Siswa dengan pola tidur yang lebih teratur rata-rata memiliki nilai sekolah yang lebih baik.
Namun periset tidak menemukan perbedaan signifikan dalam durasi tidur rata-rata antara kebanyakan siswa dengan pola tidur tidak teratur dan tidur biasa.
