The cold air is coming. Are you wearing your long johns correctly?

A new round of cold air is coming! The Central Meteorological Observatory predicts that from the night of November 8 to November 13, a strong cold air will successively affect the middle and lower reaches of the Yangtze River and most areas to the north of it from west to east, bringing significant strong winds and cooling weather, and widespread rain and snow in northern China.

It’s getting cold. Have you put on your long johns?

As it is the beginning of winter, many people have stocked up on autumn clothes, autumn pants, and down jackets in preparation for the winter.

But have you ever felt that the weather is hot and cold? If you wear long johns, you will feel hot. If you don't wear them, you will feel cold. How should you wear long johns?

When should you wear long johns?

Have you received frequent reminders to wear long johns since the beginning of autumn?

It’s the beginning of autumn, it’s time to wear long johns.

It’s the Cold Dew season, so it’s time to wear long johns.

It’s the beginning of winter, time to wear long johns.

Although long johns have gradually become a hot word, there are also many people who believe in "cover up in spring and keep warm in autumn" and that a little cold can enhance cold resistance, so they wear long johns from the beginning of autumn to the beginning of winter.

However, in order to keep our bodies warm, we should avoid getting cold, especially for the elderly, people who stay outdoors for a long time, and people who often have cold hands and feet. As soon as the weather gets colder, autumn johns should be put on early.

In terms of temperature, when the temperature drops to 15℃, thin long johns can be worn. When it is 10℃ or lower, fleece long johns can be worn. When the daily minimum temperature is below -10℃, cotton trousers should be worn.

Which long johns are the most comfortable and warm?

Autumn trousers, woolen trousers, thermal trousers; tight, loose; pure cotton, cashmere, polyester...which one should I choose?

In terms of fabric, cashmere long johns are the best for keeping warm, and they are also the favorite of middle-aged and elderly friends. However, people who are allergic to wool should wear them with caution. Polyester fabrics should be carefully selected, as they are prone to static electricity and are not friendly to people with dry and itchy skin. In terms of tightness, long johns should be moderately tight, close-fitting but not tight.

Many people like to wear very tight thermal pants to avoid being bloated and to make their legs look good. But in fact, too tight thermal pants will affect the blood flow in the lower limbs and the transfer of heat, and they will not keep you warm.

In addition to the "bare leg artifact" that can keep warm and show the leg effect, there is another familiar face in this year's autumn trousers fashion items.

That’s right, it’s the old-fashioned floral long johns that we once resisted!

This kind of long johns is generally made of pure cotton and has good air permeability. Many netizens shared their purchase and wearing experience: loose, comfortable and breathable, but it is not easy to buy now.

After many years, fancy old autumn johns have finally regained their dignity!

However, thermal underwear should not be too loose, otherwise the air will flow between the thighs and the thermal underwear, and you will still feel cold.

Will I get cold legs if I don’t wear thermal underwear?

Although wearing long johns has become a trend, there are still some people who retain their last bit of stubbornness: they refuse to wear long johns!

These people may be in the south, and they firmly believe that if they shake off, the winter will pass.

These people may be in the north, where there is sufficient heating and they rarely stay outdoors, so they only feel cold very rarely.

So will those people who refuse to wear long johns get cold legs? The answer is not necessarily!

Old cold legs is also known as "arthritis". The direct cause of arthritis is not cold, but joint injuries caused by exercise and trauma, aging of articular cartilage, inflammation caused by abnormal immune function, etc.

The reason why your joints hurt when the weather gets cold is because there are problems with the joints themselves. The sensory nerves around these diseased joints are more sensitive to cold stimulation and transmit pain signals to the brain, so when the weather gets cold, the cold legs become more serious.

Although wearing long johns cannot prevent cold legs, it can alleviate the pain to a certain extent. So it is still recommended to wear long johns.
