Tips for sun protection in three winters: Many people think that ultraviolet rays are strong in summer, so we should pay attention to sun protection. However, the weather is getting colder and the sunscreen has just been used up, and few people will "make up for it". In fact, even if winter comes, we should pay attention to sun protection, which is something we have to do every day all year round.

Tips (1)

Don't change what you shouldn't.

Many people think that sunscreen will not be absorbed by the skin anyway, and it should not have any big impact if it is changed. In fact, according to some dermatologists, many sensitivities are caused by using inappropriate sunscreen.

Although the composition of sunscreen is relatively simple and will not be absorbed by the skin, it has a "running-in" process with the skin. Just like some masks, if they are uncomfortable to wear, there may be some adverse reactions on the skin. So, if you are used to a sunscreen, don't change it easily. Long-term use is recommended.

Some skin care products have been used for a long time, and the skin has a certain "immunity", which seems to have no effect. It should be replaced. Sunscreen does not have this problem, but the skin will have a "memory function" and adapt to a sunscreen. If you change it easily, it may be counterproductive.

Suggestions for Scholars (2)

What needs to be changed still needs to be changed.

Of course, it is not absolute to say that you should try not to change sunscreen. Because from summer to autumn, there will still be a seasonal change, and the ultraviolet intensity and life schedule may be adjusted relatively. If it is not replaced according to the actual situation, it may make sunscreen a burden on the skin.

In summer, we are generally in favor of using sunscreen with SPF30 or so. If we are exposed to the outdoors for a long time, the index can be higher. In autumn and winter, the intensity of ultraviolet rays may not be so strong, and there are fewer events like swimming. We suggest that you can adjust the SPF index to 15-25. Because the higher the index, the greater the pressure on the skin, so there is no need to be too high.

It is also a good choice to buy SPF foundation in winter. For summer, the foundation may be too thick, and it is easy to blush when sweating, but in autumn and winter, it is a good thing to kill two birds with one stone, which can not only protect the sun, but also modify the skin.

Tip (3) Who decides to change or not?

Do you want to change or not? Actually, you have to ask your own skin. Everyone's skin will be different, so it is not absolute.

For example, people with different skin colors have different skin structures and different requirements for sun protection. According to the simplest data, with the same ultraviolet intensity, European and American white-skinned women will have sunburn symptoms in 5 minutes, while oriental yellow-skinned women can support 15 minutes, a difference of three times. Therefore, students with white skin should pay more attention to sun protection, and can appropriately improve the sun protection index.

For another example, oily skin should choose a liquid sunscreen with strong penetration; Dry skin should choose cream sunscreen; Normal skin is suitable for both In different seasons, your skin may take on different states. It may be oily in summer and neutral in autumn and winter, so whether to adjust sunscreen products depends on your skin.

The cold current in winter often makes people cringe and tremble, so many people try their best to keep warm-curl up and sleep under the quilt; Indoor air conditioning, doors and windows closed; In order to keep out the cold, it is equipped with thermal underwear, sweaters and trousers, plus "supporting facilities" such as down jackets, hats, scarves, masks and gloves. So which part of your body should you pay attention to to to keep warm in winter? Take a look at these tips for keeping warm in winter.

First, common sense of keeping warm in winter: the head, chest, abdomen and feet are the key points.

1, keep your head warm

Medical research has found that when the ambient temperature is 15℃, the heat lost from the head accounts for 30% of the whole body heat, and the heat lost at 4℃ accounts for 60% of the whole body heat. In addition, the cold weather makes blood vessels contract, and people will have headaches and dizziness. For people with cerebrovascular diseases, it is easy to induce cerebrovascular diseases. It can be seen that it is very important to keep your head warm.

2. Keep your chest and abdomen warm

People often say that wearing a scarf in winter is like wearing an extra dress. After catching cold in the chest and abdomen, it is easy to break the body's yang and lead to a heart attack. In addition, it can also induce gastrointestinal diseases, so keeping warm in the chest and abdomen is also a link that cannot be ignored.

Step 3 keep your feet warm

Feet are farthest from the heart, blood supply is slow and less, subcutaneous fat layer is thin, and warmth retention is poor. Once caught cold, it will reflexively cause the capillary contraction of respiratory mucosa, which will reduce the disease resistance and lead to upper respiratory tract infection. Therefore, we should strengthen the warmth of our feet in severe cold. Old people should wear thick socks and cotton shoes as soon as possible in winter to warm their feet and strengthen their kidneys. People with a history of frostbite should wear it early. In addition, before going to bed at night, scalding your feet with hot water and rubbing the Yongquan point in the center of your feet to maintain good peripheral blood circulation is conducive to health care. For people with a history of frostbite, you can wash and iron your feet with hot water with scallion and pepper.

Step 4 keep your back warm

Traditional Chinese medicine believes that the back is inhabited by kidney veins, and colds often start from the back. Therefore, keeping the back warm can not only prevent colds, tonify the kidney and strengthen the waist, but also prevent the recurrence and aggravation of old diseases. Therefore, it is best for the elderly to add a vest in winter. It is advisable to use cotton or silk floss, which has good heat preservation and cold preservation performance. Wear clothes when you get up at night to prevent catching a cold.

Second, you should also protect yourself from the sun in winter

The sun in winter is comfortable and warm. It is good to sunbathe for a while every day, because proper sunbathing is beneficial to the body's absorption of calcium, but sunbathing should also be limited. If the time is too long, it will be harmful to your health. Because too much Sun Long exposure will damage the skin, destroy the natural barrier of human body, make harmful chemicals and microorganisms in the atmosphere invade human body, cause infection and induce many diseases. Infants and young children have delicate skin and cannot be directly exposed to the sun for a long time.

Dermatologists remind that sunscreen protection should also be done in winter, because ultraviolet rays in winter can also cause harm to the skin.

Second, winter sports.

Because of the cold weather in winter, people are reluctant to go out for exercise. In fact, the colder you are, the more you should exercise, because exercise is the best way to drive away the cold, and it can also enhance the disease resistance and reduce the occurrence of diseases. For winter sports, you can choose jogging, cycling and playing Tai Ji Chuan. And you can also choose indoor fitness places, such as aerobics, table tennis, bowling and so on. But when the elderly exercise, they must do what they can, and don't choose those sports with too much activity and too much exercise.

Third, keep warm in winter and eat more foods containing iron and calcium.

Fear of cold is related to calcium deficiency and iron deficiency. People's fear of cold is related to their lack of intake of certain minerals. For example, the content of calcium in human body can directly affect the elasticity and excitability of myocardium, blood vessels and muscles; Iron deficiency in blood is an important cause of iron deficiency anemia, which is often characterized by low fever and hypothermia. Therefore, supplementing foods rich in calcium and iron can improve the body's ability to keep out the cold. Calcium-containing foods mainly include milk, bean products, kelp, seaweed, shells, oysters, sardines, shrimp and so on. Iron-containing foods are mainly animal blood, egg yolk, pig liver, soybeans, sesame seeds, black fungus and red dates.

Fourth, keep warm tips

1, often drink boiled water for health.

In winter, the climate is dry and people are prone to lack of water. Drinking boiled water often can not only ensure the needs of the body, but also play a role in diuresis, detoxification and waste removal.

Using 10 jujube and 5 ginger to decoct tea once a night can enhance the cold resistance of human body and reduce diseases such as colds.

It can enhance the cold resistance and disease resistance of human body and prevent colds and colds.

4. Citrus oil or peppermint oil is often placed beside the bed.

Citrus is warm and has a strong smell, which can get rid of viruses. Putting oranges on the bed can prevent upper respiratory diseases; Eating a few petals of oranges before going to bed can relieve phlegm and cough. Put a small bottle of peppermint oil on the pillow and cover it with a leaking cork to let the peppermint oil gas dissipate slowly. It also has the effect of treating headache and nasal congestion.

5, sleep at night mulberry pillow

Winter mulberry leaves and autumn chrysanthemums can clear the eyes and refresh the mind to treat colds. Using it as a pillow core can refresh the mind, make people fall asleep comfortably and prevent colds.

Experts remind people that indoor ventilation should be frequent in winter to ensure that people can breathe enough fresh air. In order to prevent the indoor air from drying, you can put a basin of water indoors or near the heating, or you can choose a humidifier to keep the indoor air moist. At the same time, pay attention to drink plenty of water. It is best to drink a glass of water before going to bed at night and after getting up in the morning to ensure that there is enough water in the body.

4. What are some tips about sun protection?

What are some tips about sun protection? UV ultraviolet UVA UVA UVB UVB UVB BSPF sun protection coefficient PA UVA sun protection index UVA mainly contains two kinds of rays: UVA (long wavelength black spot effect ultraviolet ray) can penetrate the skin, causing cell damage, that is, collagen loss and skin aging.

However, UVB with shorter wavelength (ultraviolet ray with erythema effect) acts on the surface layer of skin, which mainly causes skin redness and sunburn. PA value represents effective protection time: PA+ is about 4 hours, which means effective PA++ is about 8 hours, which means particularly effective pa++ strong protection, which means very effective SPF, that is, the time for skin to resist ultraviolet rays. If your skin starts to turn red after 10 minutes in the sun, you can use SPF 15 sunscreen to ensure that 150 minutes (15x 10 minutes) will not get sunburned.

Therefore, the greater the SPF value, the longer the validity period of sunscreen.

5. About applying sunscreen in winter

It is generally not necessary to apply sunscreen in winter. As MM herself said, using too much sunscreen is always a bit counterproductive.

First of all, ultraviolet rays are not strong in winter. But if your sun is bright, you can apply a layer of isolation cream after applying moisturizing cream. The sunscreen cream is better than the sunscreen cream, and it has a certain effect of isolating and reflecting ultraviolet rays, which can not only effectively protect the sun but also refine the skin. . Of course, when you go back at night, good makeup removal steps are inevitable, otherwise your skin will go bad.

Finally, if you haven't used cream before, or if your cream feels dry or too white, you can mix cream with moisturizing cream and apply it evenly on your face with a puff, and the effect is also very good.

6. Winter safety knowledge 50 words

Some common sense of fire prevention and theft prevention in home safety.

"The weather is dry, beware of fire". The northern winter climate is dry, so fire prevention in winter is very important. I would like to remind you that volatile oils such as gasoline, alcohol and banana oil are easy to cause fires, so don't store them in large quantities at home.

In addition, the dirt and oil in the kitchen should be removed at any time. Special attention should be paid to the fume ventilation pipeline, and a barbed wire cover should be installed to reduce the grease from entering the ventilation pipeline. Kitchen walls, ceilings, stoves, etc. , fireproof materials should be used.

If the window is equipped with anti-theft net, a movable door should be left, and it should be opened when necessary to escape. Lock the windows at ordinary times to prevent thieves from entering.

Before going to bed and going out every day, check whether the appliances and gas at home are turned off and whether the open flame is extinguished. Read the instruction manual of the electrical appliance carefully and use it according to the instruction manual. Especially electric heaters, electric water heaters and other high-power appliances.

Make sure that the door is equipped with a security door chain and cannot be removed from the outside. Don't hide the key outside the door where you feel safe. If you want to leave home for a while, you should tidy up your newspapers and mailboxes to avoid being found that no one is at home for a long time. If you are not at home at night, leave the light indoors.
