今日の日の入り時刻・・・年間で最も遅い

　国立天文台によると、今日６月２５日の日の出は４時２７分です。ところが、夏至が過ぎても、日の入り時刻は「今日が年間で最も遅く１９時０６分」【いずれも群馬県】です。

　今後７月～８月は昼の時間が長く気温の上昇はこれからが本番です。夏至の頃より夏至の後に暑くなるこのズレの原因は、太陽高度が暫く７０°台であったり、地球の海と陸の割合がおよそ７対３のため、海は陸の2倍以上の面積があることから海水に影響を受ける地球は、夏至でもすぐに温まり難く、一方、冬至より１月～２月が寒冷なのはすぐには冷め難い性質があると考えられます。

　上記の理由で暑さはこれからが本番です。ところで、成人の場合、体重の約60％が水分といわれ、一方、幼児は70％ほどで成人より高いといわれます。ご存じの通り、体内の水分は「血液として酸素や栄養素の運搬、老廃物の排泄や、体温調節」に重要な役割を担うことから、私たちは体内の水分を一定に維持することが各臓器のために必要不可欠なことです。

　体重に対し1～2％程の水分が損なわれるだけでも軽度の脱水症状として現れ、更に進むと熱中症になりやすく、これを未然に防ぐため、私たちは「喉が渇く前の」水分補給が大切です。

　ところで、ここだけの話ですが、「充分な水分補給」があると、結果的に、便秘解消に大きな効果があります。

Dear my friends who are crazy about rehydration and great music.

　The simultaneous interpretation into English for our mutual understanding will be done after my breakfast in Japan time.

　According to the National Astronomical Observatory Japan, today, June 25th, sunrise was at 4:27. However, even though after the summer solstice, the sunset time is "today is the latest of the year at 19:06" [both in Gumma Prefecture which is situated in the center of Japan].

　Generally, the days will be longer and the temperature rise will start from now on. The reason for the delay in getting hot after the summer solstice is that the solar altitude will be in the 70° range for a while, and the ratio of ocean to land on the earth is about 7:3, so the ocean's area is more than twice that of land, so the earth is affected by seawater, as the result the earth does not warm up quickly even at the summer solstice. On the other hand, January and February are colder than the winter solstice because it does not cool quickly.

　For the above reasons, the heat is about to start from now on. By the way, it is said that about 60% of adult's body weight is water, while for infants it is about 70%, which is higher than adult. As you know, water in the body plays an important role in "transporting oxygen and nutrients as blood, excreting waste products, and regulating body temperature," so maintaining a constant amount of water in the body is essential for the health of our each organs.

　If losing even 1-2% of water in our body weight can cause mild dehydration, and if it progresses further, we are more likely to develop heatstroke. To prevent this, it is important for us to hydrate before we get thirsty.

　By the way, just between you and me and lamppost, "sufficient hydration" can ultimately be very effective in relieving constipation.
