The weather in the north is dry, and southerners don't adapt here. The nose is particularly dry and uncomfortable. what can I do?

2. Eat more fruits and vegetables.

3. Vitamin supplements

4. Add humidifiers indoors

5. Keep the humidity of indoor air.

The difference between north and south is closely related to the geographical location of China and the different climate characteristics between north and south. To sum up, there are several main points:

China is a vast country. The distance between north and south is far, geographically speaking, it is lower in the south and higher in the north, with a difference of more than 30 degrees. In the northern hemisphere, the sun shines directly into the southern hemisphere in winter, which leads to stronger or longer solar radiation intensity and sunshine duration and higher temperature in the south than in the north. This is due to the latitude position. Different latitude positions lead to different solar radiation.

In summer, the sun shines directly in the northern hemisphere. Although the radiation intensity in the south is still greater than that in the north, the sunshine time in the north is longer than that in the south, so the difference of solar radiation between the north and the south will not be as great as that in winter. The temperature difference is not that big.

2. In the north, affected by the cold high pressure in Mongolia and Siberia in winter, cold air often goes south to form a cold wave, which greatly reduces the temperature. The south is affected by the warm and humid air flow from the ocean, and the winter is mostly mild. This is caused by the climate.

3. East-west mountains, such as Qinling Mountains, block the southward movement of cold air mass, which makes the temperature in the south high and the temperature in the north low, and the temperature difference naturally increases. This is due to the terrain.

Under the comprehensive effect of many geographical factors (solar radiation, climate and topography), the temperature difference between north and south in China is much larger in winter than in summer.

Avoid licking your lips frequently:

Some people think that chapped lips can be licked with the tongue, but the result is just the opposite. Saliva is secreted by salivary glands and contains amylase and other substances, which is relatively viscous. After licking your lips, it seems to be covered with a layer of paste. When the water evaporates, the lips will be drier. If your lips are dry and uncomfortable, apply lip balm without pigment and fragrance.

Avoid pure glycerol:

People usually use glycerol containing 20% water. If pure glycerin is used, its water absorption capacity is too strong, which will absorb the moisture in the skin, but it will make the skin drier.

Avoid wearing too much:

If you wear too much and too thick, the blood vessels in the skin will expand, and the blood flowing to the skin will increase, thus increasing heat dissipation. This reduces the body's ability to adapt to changes in external temperature.

Keep your skin moist and take a scientific bath;

There are four taboos in bathing in winter: avoid being too diligent, the water is too hot, the rubbing is too heavy, and the soap is too alkaline. Otherwise, it is easy to destroy the original sebum on the skin surface, making the skin drier and therefore more itchy and chapped. The number of baths should be 2-3 times a week. After bathing, you can rub some licorice oil, antipruritic cream, moisturizing cream and so on. Keep the skin moist and prevent the skin surface from drying off.

Thermal insulation and cold protection:

In winter, the temperature is low, and exposed parts of the skin are prone to frostbite, such as hands, head and neck. Others, such as feet, are also prone to freezing, so we should pay attention to the cold and warmth of these parts, such as wearing scarves, gloves, earmuffs and cotton shoes to keep warm, rubbing hands and ears at any time, and exercising in time. Avoid wearing wet clothes, shoes and socks. Meanwhile, dry your hands and face before going out.

Avoid using inferior skin care products:

Inferior skin care products are toxic to the skin because of impure texture or heavy lead content. Some cosmetics contain some sensitizing spices, some people will be allergic after using them, and even increase the skin pigment, causing harm to the skin. In winter, under the condition of less sebum, the damage is greater.

Strengthen exercise:

Strengthen skin exercise and enhance skin adaptability to adapt to the cold environment. You can take a cold bath, an air bath, sunbathing, massage, etc. Still insist on washing your face with cold water and wiping your body with cold water.
