🐝 Pourquoi une abeille perd autant de chaleur en hiver ? La réponse est physique, pas instinctive. C’est la loi de Stefan-Boltzmann : plus un corps est chaud, plus il rayonne de chaleur… et à la puissance 4 ! 🔥 Une abeille à 36°C rayonne énormément. ❄️ Si la paroi est à 5°C, elle absorbe toute cette énergie → énorme perte. Résultat : surconsommation, stress thermique, grappe figée. 👉 La solution ? 1. Isolation continue des parois pour limiter les pertes. 2. Film thermoréflecteur pour renvoyer
