Insensitive to hot and cold weather

I come from Guangzhou and often work in the north. I feel that the biggest difference between north and south is humidity. So not only the temperature but also the humidity should be considered.

In Xi 'an, 42 degrees, it was dry, and the specific humidity was not measured. My throat is like a fever and my body is not sweating.

In Guangzhou, under the temperature of 42 degrees, the humidity is probably above 80%, sweating all over, sweating all over, and my underwear is wet. But my throat is not dry.

Body contact temperature, such as sitting on the sofa, feels a little hot when the temperature exceeds 3 1 degree.

The same temperature of 28 degrees, in the humid weather in the south, will feel sultry, in the dry weather in the north, will feel neither cold nor hot, just right.

When the temperature is below 24 degrees, clothes are usually added, so it is not sensitive to temperature.

In the cold storage where the temperature is -2 1 degree, I have been working in a single coat, trousers and a thin down jacket 1 hour. Cold hands and feet, slow movement. After eating at 35 degrees for 40 minutes, I didn't feel hot at all. My hands and feet returned to normal just after dinner.
