استشاري قلب يحذر الطلاب: السهر أخطر من صعوبة الامتحان

حذر استشاري وأستاذ أمراض القلب وقسطرة الشرايين الدكتور خالد النمر، الطلاب والطالبات من السهر ليلة الاختبار، مؤكداً أن العدو الأول للطالب قبل الامتحان ليس صعوبة المادة الدراسية، وإنما قلة النوم التي تؤثر بشكل مباشر على الأداء الذهني والقدرة على استرجاع المعلومات.

وأوضح «النمر» أن الدراسات أثبتت أن نقص ساعات النوم يؤدي إلى ضعف استرجاع المعلومات من الذاكرة، وانخفاض الانتباه والتركيز وفهم الأسئلة بدقة، إلى جانب بطء التفكير والتحليل واتخاذ القرار.

وأضاف أن الطالب قد يكون على دراية بالإجابة الصحيحة، لكن إرهاق الدماغ يمنعه من الوصول إليها في الوقت المناسب، مشدداً على أن النوم الجيد لمدة تتراوح بين 7 و8 ساعات ليلة الاختبار يعد جزءاً أساسياً من عملية المذاكرة والنجاح.
