هل تتحكم درجة الحرارة في مواعيد نومنا؟

هل تتحكم درجة الحرارة في مواعيد نومنا؟

ملخص الخبر

يرى بعض العلماء أن درجة الحرارة قد تعادل أهمية الضوء في تنظيم الساعات البيولوجية اليومية للجسم.
أظهرت دراسات على سكان أصليين أن مواعيد نومهم تتبع تغيرات درجات حرارة البيئة المحيطة بدلاً من دورات الضوء.
تساهم تقلبات درجات الحرارة في تحفيز هرمون الميلاتونين وزيادة الشعور بالانتعاش عند الاستيقاظ.
تعد دراسة دور درجة الحرارة كإشارة مستقلة لضبط الساعات البيولوجية لدى البشر موضوعاً لا يزال قيد البحث.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

هل يمكن أن تكون درجة الحرارة مفتاحاً خفياً يحدد متى نشعر بالنوم ومتى نستيقظ، إلى جانب الضوء الذي اعتدنا اعتباره المنظّم الأساسي لساعتنا البيولوجية؟
