لماذا يعتقد العلماء أن أجدادنا ربما كانت أجسادهم أعلى حرارة؟

ما يعرفه ريفو عن الخبر

  • تشير الأبحاث إلى أن متوسط درجة حرارة جسم الإنسان كان أعلى قبل 150 عاماً مما هو عليه اليوم.
  • يرجع العلماء انخفاض الحرارة الحالية إلى تحسن الصحة العامة، وتوفر اللقاحات، والتحكم في درجات حرارة الأماكن المغلقة.
  • قد يعود جزء من التباين التاريخي إلى عدم دقة معايرة موازين الحرارة القديمة مقارنة بالأجهزة الحديثة.
  • تتأثر درجة حرارة الجسم بعوامل بيولوجية وبيئية تشمل العمر، والجنس، والوقت من اليوم، والطول، والوزن.

الأبحاث الحديثة تشير إلى أن متوسط ​​درجة حرارة الجسم الطبيعية قد تغير بالفعل على مدى القرن ونصف القرن الماضيين. فهل كان المعيار الأصلي خاطئاً؟ أم أن عالمنا سريع التغير يؤثر على طبيعتنا البيولوجية؟
