Why do wet places feel colder than arid places when it s cool?

In humid places, the air humidity is relatively high, making the temperature lower.

There is moisture in wet places, and when moisture enters the body, it forms a dampness that makes the body feel colder.

When it's cold, a lot of moisture is formed, and as soon as the moisture enters the bones, people feel cold, and they feel cold.

This is because the air contains a lot of moisture and will absorb heat.

This is because the temperature is lower in humid places.

Because a lot of moisture is formed in the air.

Water that becomes gaseous absorbs heat.

As soon as the moisture gets into the bones, it makes people feel cold.

Because the weather is very dry, the temperature is very low, and people's bodies are also very cold, so they will feel very dry.

1. Different humidity pie bucket molds: wet cold and dry cold, the main difference is the difference in humidity. It is dry and cold, the north wind is strong and dry, although the wind is cool, but this is only the temperature around the drop, and the temperature of the human body does not change much.

Damp and cold, that is, low temperature and high relative humidity of the air, the human body temperature is significantly lower than the surrounding environmental temperature.

2. The impact on ** is different. When the humidity is low and the air is dry, the skin will face severe dehydration. When the blood circulation is slow down when it is wet and cold, it disturbs the balance of water and oil, the absorption of skin care products is slow, and the dry dust and slow wrinkles appear in the air-conditioned environment.

In winter, dry cold is cold, feeling biting cold, and wet cold is feeling cold with water on the body, which is particularly uncomfortable.

Dry cold just stays on the surface, you can wear more clothes. Clammy cold is the kind of cold that seeps into the bones.

At the same temperature, a place with high humidity makes people feel colder than a dry place, because the water needs to absorb heat from the air during the transition from liquefaction to vaporization, and when the heat in the air is absorbed, the surrounding temperature will drop, which causes our body to feel colder. In the same way, just like when we open the lid of a hot pot, it will be very hot when the hands are washed by steam, because the water changes from vaporization to liquefaction, and in the process, it releases heat, so that it feels hotter than the inside of the lid.

The same temperature and humidity make people feel colder than dry places, and this phenomenon is especially noticeable in winter. If a Harbin person goes to Nanjing, with the experience of spending the winter in Harbin over the years, he will definitely feel that the outdoor temperature in Nanjing is much lower than that in Harbin, this is because the humidity in Nanjing is much higher than that in Harbin, which affects the feeling of coldness in the human body. NanjingBecause the humidity in the air is very high, the water changes from liquid to gaseous, it needs to absorb energy to carry out, and in this process, the surrounding temperature will be reduced, and the temperature that the human body can feel will be lower.

Since then, the humidity in the air in the south is high, and the humidity of the clothes people wear is correspondingly high, and the heat emitted by the human body in this process is provided to the damp clothes, resulting in us being wrapped in clothes can not feel warm, so we will feel cold.

In the same way, the increase or decrease in the temperature in the air determines the level of humidity in the air. At a certain temperature, water is mainly in the form of liquid, and then the higher the temperature, the higher the degree, the higher the moisture in the air. The cooler the temperature, the lower the moisture in the air, because the moisture in the air has been converted to a liquid or solid state.

In summer, the greater the humidity in the air, the weaker the body's ability to evaporate and dissipate heat, which will make people feel hotter, and in winter, because the humidity increases, it will speed up the heat dissipation, so that the human body feels very cold.

In places with high humidity, there is more moisture content in the air, and these moisture contact people's **, and because the human body temperature is higher than the temperature of moisture, water evaporates and absorbs heat, taking away part of the heat of the human body, and it will naturally feel colder.

In a humid place, people feel colder than a dry place, mainly because these moisture will form some cold water droplets scattered in the air, and the human body will feel particularly cold.

Because the heat is low in a humid place, and because the evaporation of water needs to absorb heat, the cold with high humidity is more likely to take away the heat of the human body, so it is colder.

Because in places with high humidity, moisture sticks to people's **, and when it evaporates, it will take away the heat on people, so it is easier to feel cold.

When the temperature is relatively high, the human body needs to dissipate heat. The human body mainly relies on sweating for heat dissipation, and sweat volatilization will take away heat. In places with high humidity, the evaporation rate of water is affected, so the heat dissipation rate is slower, so the body feels hotter.

So when the temperature is high, the humid place will feel hotter than the dry place. You can use this method to predict the perceived temperature, this method is called the heat index, or humiture, which appeared in the late 1970s, and some places have this index in the weather forecast. However, this index does not take into account other weather indicators of the day, such as sunshine, wind speed, rainfall, etc., and now some companies have developed a special calculation formula that takes these factors into account to calculate the perceived temperature.

When the weather is cool, there is also an index used to describe the feeling temperature, the simplest is called the wind-chill index, which is concerned with the wind speed. The greater the wind speed, the faster the warm air outside the surface is replaced by cold air, and the person will feel colder. This index was developed during World War II and used in the polar temperature range, and has been used by meteorological departments of some countries since the 1970s for forecasting, but it seems that there is a lack of uniform standards for each country.

Because just as there is heat outside on a hot day, there is moisture in a humid place.

When it's cool, the moisture will unconsciously eat away at your bones, so it's colder than in arid places.

The moisture will continue to vaporize, so it will be colder.

Because water vapor evaporates in wet places, it will be colder.

Because wet places will get your clothes wet, and it will be colder.

Because moisture penetrates into the human body, it can't be stopped, and clothes can keep out the cold in arid places.

The more humid the place, the heavier the moisture, and the moisture will unconsciously invade the body.

Wet places are magical attacks, and arid places are physical attacks.

Because when the gas evaporates, it will absorb heat.

Water evaporation will absorb heat, so people will feel cold.

Humid air makes it easier to lower the temperature.

Because this kind of place will make people even colder.

Because humid places have heavier moisture in the air.

Because the water on the ground will absorb heat, and it will be colder.

Humid places have more moisture and are more likely to get cold.

Because where there's water, it's actually colder.

It's like it's a physical reaction.
