Are people from the South really resistant to the cold?

At the beginning, the cold air from the south was also relatively dry and cold, but due to its short duration, the humidity in the south quickly returned to normal. Therefore, the north is dry and cold, while the south is wet and cold. Wet cold does not mean there is a high amount of water vapor in the air; rather, it means the air is filled with tiny liquid droplets with diameters of just a few micrometers. For example: even if the room temperature is higher than that of the pool water, you will feel colder once you get out of the pool – that’s why. Newton’s law of thermal conduction cooling (also known as the cooling law) can also well explain why wet cold makes people feel colder. It’s okay if you can’t understand this sentence; you just need to know that the heat loss of an object is related to both the temperature difference and the thermal conductivity. The thermal conductivity of water is 0.5815 W/m·K, whereas that of still, dry air is only 0.0233 W/m·K – a difference of more than 20 times. Those hidden tiny droplets in the southern air take away all the heat from your body.

God is fair: high temperatures result in humidity, while low temperatures lead to dryness. Now you know that turning on the dehumidification function of the air conditioner at home can make it much warmer, perhaps even more effective than the heating function. 2 Does heating make people feel colder? Almost every person from the South who has spent a long time in the North has had a similar experience: after getting used to life in the North and returning to their hometown, they find themselves too timid to go around without wearing clothes from head to toe. Does heating really make people \"degenerate\"? If one lives in an environment with heating for extended periods, or if the indoor temperature is kept high during winter by other means, the ability to tolerate cold does indeed decline significantly; this is probably what is meant by the saying \"use it or lose it.\"

At the same time, because they are accustomed to a warm environment, they unconsciously set higher standards for indoor temperatures in winter. Northerners who come to the south for the first time* are used to the dry and cold climate of the north, and they have little resistance to the damp and cold weather in the south; this is why Southerners seem more resistant to the cold. The study \"Research on Adaptive Thermal Comfort Based on Regional Climate\" shows that in winter, for people from southern regions living in humid and cold areas, as long as the perceived temperature is around 10°C, they do not feel particularly cold; in contrast, people from northern regions need a temperature of around 20°C to feel that it is not too cold. Within the temperature range that people can tolerate in winter, those from the south still fare better than those from the north. Due to indoor heating, even though it is extremely cold outside in the Northeast, North China, and Northwest regions with very low temperatures, people still consider the temperature to be \"acceptable\" – it’s not too low; such temperatures are around 7°C or higher. The temperatures are particularly high in the northeast and northwest regions, reaching over 10°C. In the humid and hot southern regions, where temperatures that are considered “acceptable – any lower and it would be too cold” are the lowest among all climate zones, at 6.3°C, people from the south clearly have a greater tolerance for cold than those from the north. Finally, for those children who are sensitive to cold, it is important to wear more clothes, consume foods rich in iron and calcium, drink plenty of plain water, and soak their feet in hot water before going to bed at night, so as to have a warm winter!

So it seems the south will need to install heating too

Install it yourself: air conditioning, underfloor heating, electric heaters

A hot water bottle, a household heating device that is filled with hot water and placed under the blankets to raise the temperature. It is a flat, round pot made of copper or magnetite, with an opening at the top equipped with a nut; hot water is poured in through this opening. It is available in various materials such as copper, tin, and ceramic; it generally has a pumpkin shape, a small mouth, and a stopper inside the lid to prevent leakage. The water-filled \"hot compress\" has its nut tightened, and then it is placed in a bag of similar size inside the bedding, ensuring warmth while sleeping at night. It existed already during the Song Dynasty.

As a northerner in the south, I initially thought that people from the south were more tolerant of cold, but now I am tolerant of cold as well. Actually, in the south, the temperature is cold for just a short period of time; you can endure it and it will pass.

I see, I remember when I was a child I would use a glass bottle used for infusions to hold hot water and hug it haha
