いろいろ工夫し、猛暑を乗り切りましょう。

　毎日、猛暑続きです。皆様、いかがお過ごしでしょうか。暑い暑いと言っても、今日は夏至からすでに１ヶ月と１週間が過ぎました。

　因みに、夏至の日の出時刻は４時２６分(群馬県)でしたが、今日７月１７日の日の出時刻は４時４６分ですら、すでに２０分も日の出が遅くなってます。同様に、日の入りも早くなってるので、昼の長さは夏至の頃より４０分も短くなってます。これを知ると寂しくなります。

　しかも、一週間後は二十四節気の一つ「立秋」ですから、暦の上ではもうすぐ秋です。このように実際の気温と暦にずれがある理由は、以前に書きましたが、私たちの環境である「地面は温まり難く、冷め難い性質がある」からと考えられます。

　一方、南半球のニュージーランドなどでは現在が真冬で、南極の昭和基地では現在、毎日が夜が続いています。想像を絶する寒冷地ですから、越冬隊員はどれほどか寒いことでしょう。

　私が住む群馬県も連日猛暑ですが、山岳地方に行って涼んだり、日帰り温泉で汗を流すとサッパリし、生きる力が湧いてきます。写真は群馬県北部にある鳥の巣のように大木の途中に作った山小屋で、風が吹くと揺れ、涼しさが満喫できます。

Dear my friends abroad

　The heatwave continues every day in the Japanese archipelago. How are you all doing, my friends on Facebook? Even though it's hot, it's already passed a month and a week since the summer solstice.

　Incidentally, the sunrise on the summer solstice was 4:26 (Gumma Prefecture), but even today, July 27th, the sunrise is 4:46, which is already 20 minutes later. Similarly, the sun sets earlier, so the length of a day is 40 minutes shorter than at the summer solstice. It makes us sad to know this.

　In addition, one week later is the beginning of autumn named "Risshu", one of the 24 solar calendars, so autumn is just around the corner according to the calendar. As I wrote before, the reason for this discrepancy between the actual temperature and the calendar is thought to be because in our environment "the ground has the property of being difficult to heat up and difficult to cool down."

　On the other hand, it is currently mid-winter in New Zealand in the southern hemisphere, and at Showa Station in Antarctica, night continues every day. It is an unimaginably cold place, so I wonder how cold it must be for the wintering team members.

　

　Gumma Prefecture where I live has been experiencing scorching heat every day, but going to the mountainous regions to cool off or washing off the sweat in a day spa makes me feel refreshed and gives me the strength to live.

　The photo shows a mountain hut built halfway up a large tree like a bird's nest in northern Gumma Prefecture, it sways when the wind blows, allowing us to fully enjoy the coolness.
