قاعدة النوم 8 ساعات تحتاج لإعادة النظر… دراسة جديدة تكشف المدة المثالية

ما يعرفه ريفو عن الخبر

تشكك مراجعة علمية حديثة في قاعدة النوم لثماني ساعات كمعيار موحد لجميع البالغين.
تشير دراسات إلى أن مدة النوم المثلى قد تتراوح بين 6.4 و7.8 ساعة حسب الجنس والظروف.
يعد توقيت النوم وانتظامه عاملان أساسيان يؤثران على الصحة بقدر أهمية عدد الساعات.
تختلف احتياجات النوم الفردية بناءً على العمر والظروف المتاحة مع أهمية الحصول على قدر كافٍ من النوم.

ظلّت الإجابة التقليدية عن سؤال عدد ساعات النوم التي يحتاج إليها البالغون واضحة لعقود: 8 ساعات كل ليلة.
