Tokyo has been extremely hot for 3 days in a row since Sunday 🤪

It’s pretty hot even around 8am 🥵
It’s not safe to exercise outside at 9am 😩

But the jogging course in Komazawa Park has a good environment.

Bec there are many big trees that about half of the jogging course is shaded.

And there are 5 drinking fountains along the course 💧

I think we should wash our face and cool our hands about once every 2 laps 🏃‍♂️

The palm of our hand is crowded with nerve receptors, so we can receive various sensations very sensitively.
So when we cool our palms, our temperature goes down.

人間は二足歩行になり手を自由に使えるようになりました

同時に手のひらや指を痛めると生活に影響がでるので進化の過程で敏感になりました

手で熱い物を触ると瞬間的に手を引っ込める事ができるくらい敏感にできています

手のひらや指には神経の受容体が密集しています

手のひらを冷やすと体温を下げやすいです

夏のマラソンやトライアスロンの大会でも

給水所やエードステーションで氷をもらって

袋に入れて手に持って走ると良いです
