لماذا ينام بعض الأشخاص أربع ساعات فقط يومياً؟

ما يعرفه ريفو عن الخبر

تساهم العوامل الوراثية في تفسير الاختلافات الكبيرة بين البشر في عدد ساعات النوم اليومية.
تعد طفرة جينية نادرة تسمى قصر النوم الطبيعي العائلي سبباً لتمكين البعض من النوم لفترات قصيرة مع الحفاظ على الصحة.
تحمي بعض الطفرات الجينية المصابين بها من الآثار السلبية لقلة النوم مثل ضعف الذاكرة وزيادة خطر الإصابة بالزهايمر.
تساعد الأبحاث الجينية في فهم آليات النوم لتطوير أدوية لعلاج اضطرابات النوم ومساعدة العسكريين على التكيف مع قلة النوم.

يحتاج الشخص البالغ الذي يتراوح عمره بين 26 و64 عامًا إلى حوالي سبع إلى تسع ساعات من النوم كل 24 ساعة ، وفقًا لأحدث مراجعة للأدلة العلمية أجرتها المؤسسة الوطنية الأمريكية للنوم.
