昔からこたつが好きです．暖房費が一番かからないとの理由もあって，この10年ほど（いや，もっと長きにわたり），冬の間で自宅にいるときは，ほとんどこたつに当たっています．<\/p>\n\n\n\n
部屋をあまり暖かくせずにこたつに当たると，昔から頭脳労働の生産性が高いとされる「頭寒足熱」の状態になりますが，どうもそんなに生産性が上がる気がしません．というか，むしろ下がっていると思います．<\/p>\n\n\n\n
たぶん，足の血管が拡張して血液がそちらに回り，脳の血流が低下するからじゃないかと，自分では感じています．足が温まった状態で血圧を測ると，明らかに下がっています．<\/p>\n\n\n\n
ぼうっとして，ときどきうとうとして，低い生産性を楽しんでいます．<\/p>\n","protected":false},"excerpt":{"rendered":"
