Hot and cold seem to be determined by "worst values" rather than averages.

Hot and cold seem to be determined by "worst values" rather than averages.
Today, following on from my recent speech in Hamamatsu, I gave a lecture in Numazu, located in the eastern part of Shizuoka Prefecture.
I got off the Shinkansen at Mishima station and it was only one stop from there, but it was very slow.
However, after the lecture, the attendees were very enthusiastic and asked questions.
There was someone there, but we were heading in the same direction on the way back to Mishima.
I accompanied him to the train on the way home.
By the way, today's topic is a word I've used for the first time, but I've decided to call it "worst value."
What I mean is, for example, even if the average perceived temperature in winter is 21 degrees Celsius,
If the floor temperature is around 16,7 or XNUMX degrees Celsius, it is difficult to feel satisfied.
Another example is when you go out and you take complete precautions to protect yourself from the cold except for your face and hands.
My hands are just extremely cold...
It may be easier to understand if you think of a situation like this.
It is said that the feet are the part of the body that feels the cold most easily, followed by the hands.
When it comes to room warmth, the good and bad points are generally discussed in terms of "average values."
I think there are a lot of things.
However, in my experience, no matter how hot the room is,
Even if the temperature is moderate, if the temperature at the feet does not exceed about 20℃,
It is difficult to receive positive feedback. On the other hand, if you can maintain that temperature at your feet,
I feel satisfied even with a room temperature of around 18°C.
I think the same thing happens when you go out. Even if you take proper precautions to protect your whole body from the cold, your hands can still get numb.
When it is that cold, you will be more aware of your cold hands than the fact that 9% of your body surface is warm.
I'm gone.
I think everyone knows this, but by covering up the most disadvantageous part,
This may be because it was meant to prevent frostbite.
The same can be said about air conditioning. The part of the body that feels the most heat is generally the forehead.
It is said that.
If you try this with a car air conditioner, you'll understand that even if you blow cold air from underneath,
I don't think it's comfortable. On the contrary, it's really comfortable when blowing from above.
Again, mitigating what feels like the "worst" part can have a huge effect.
This is an example.
We named the temperature of the area that feels the worst as the "worst value."
If you consider heating and cooling based on the worst case scenario, you can save a lot on heating and cooling costs while still maintaining comfort.
can be significantly improved.
