You must know in summer! When going out in summer, first "sun protection" and then "mosquito prevention". In the hot summer, "sun protection" and "mosquito prevention" are two important things to go out! Parents want to help their children achieve the complete protection of "sun protection and mosquito prevention", but they should not know which comes first and which comes later. Also, there are many sunscreen and mosquito repellent products on the market. Which is better, spraying or wiping? Please listen to the advice of a professional dermatologist! Sun protection or mosquito prevention first? In sunny summer, if you want to take your baby outdoors, you must fight against two enemies-"sunshine" and "mosquitoes". Before figuring out whether to prevent sun or mosquitoes first, let's first understand why ultraviolet rays are so strong in summer, the causes and possible harm of mosquitoes.

UVB is hot and sunny.

Every summer, I always feel that Grandpa Sun is very hard and the sunshine is particularly strong and dazzling. Dr Huang Yulin, president of Huang Yulin Dermatology Clinic, explained that ultraviolet rays that can reach the earth's surface can be divided into "UVA" and "UVB" according to the wavelength. Compared with UVA, the exposure of UVB in summer is more than that in winter, and UVB will make people feel hot, so parents will feel that the sun in summer is particularly hot and uncomfortable.

For infants, ultraviolet rays, like adults, may cause skin aging, spots, sunburn, sunburn (ranging from redness and tingling to blistering). Infants' skin is thin, only about one-third of the thickness of adults, with less pigment and poor defense against ultraviolet rays. Dr. Huang Yulin pointed out that previous studies pointed out that if you had sunburn before adulthood, you would have a higher chance of developing skin cancer later. Therefore, you should do a good job of sun protection from an early age.

Mosquito bites can produce violent reactions.

In addition to the problem of ultraviolet rays in summer, summer is also the breeding period of many insects, and the mosquito army is out in succession! Dr. Huang Yulin said that mosquitoes prefer to bite people with high body temperature, heavy body odor or fragrance. The baby's metabolism is faster and the body contains more fat to maintain the body temperature. Therefore, the baby is prone to sweating and has a high body temperature, which is why mosquitoes always like to bite the baby.

The baby's reaction after being bitten by mosquitoes is often very intense, not only the days of redness and swelling are longer and wider, but also the degree of itching is more serious and obvious than that of adults. Take your baby out in summer, especially in the suburbs with many flowers and trees, or near the water, pay special attention to prevent mosquito attacks.

Don't rub it wrong! Sun protection first, then mosquito prevention.

You must know in summer! When going out in summer, which effect is better, spraying or rubbing, which is "sun protection" first and then "mosquito prevention"? There are many kinds of sunscreen or anti-mosquito products on the market, including gel, lotion, cream and spray. Which one is better? Dr. Huang Yulin thinks that whether it is spray or emulsion, the most important thing is to have enough sun protection or mosquito prevention ability to play a role and achieve protective effect!

Sun protection: SPF30, PA++

For baby sunscreen, Dr. Huang Yulin suggested choosing SPF30 and PA++. Need to be reminded that if you use spray sunscreen, you should pay special attention to three points. First of all, most spray types contain organic solvents, so they are not suitable for use near fire sources. Second, the spray is too harmful to the mucosa and is not suitable for direct spraying on the face. You can spray it on your hands and apply sunscreen to your face. Third, the ejected aerosol particles are small and may be inhaled into the respiratory tract by children. Therefore, it is recommended to use it away from the nose and mouth. For example, when spraying the left hand, let the child turn his face to the right, or spray it on the adult's hand before smearing it for the child, so as not to burden the respiratory tract.

Mosquito control: effective with deet ingredients.

DEET, which has been approved by the Food and Drug Administration, has been proved to have anti-mosquito effect. However, DEET was considered toxic for a long time in the past, but in recent years, this suspicion has been cleared. Dr. Huang Yulin said that according to American research, babies over 2 months old can use mosquito repellent products containing DEET, adults can use mosquito repellent products with DEET concentration of 30%, and children can use mosquito repellent products with DEET concentration of 10 ~ 15% to avoid causing too much burden.

Don't forget! It takes 2 hours to make up.

Don't think that just putting on a layer of sunscreen or anti-mosquito products when you go out today is like putting on an invincible protective cover once and for all! Whether it is a sunscreen or an anti-mosquito product, you need to wipe it! Dr. Huang Yulin suggested that under normal circumstances, sunscreen should be applied every 2 hours; If you are engaged in swimming or swimming, replenish sunscreen every 30 minutes in the carriage.

Mosquito-killing products with deet concentration of 65,438+00% should be supplemented every two hours, especially the common spotted mosquitoes and house mosquitoes in Taiwan Province Province, which are more active at 9: 00 am, 65,438+00 am and 4: 00 pm. Therefore, it is necessary to supplement it during these two peak hours outdoors, so as not to lose the effectiveness of the product with sweat and time.

You must know in summer! When going out in summer, which is better, "sun protection" or "mosquito prevention" to physically cover V.S. chemical products? Whether it is sun protection or mosquito prevention, doctors will recommend wearing long-sleeved clothes to prevent ultraviolet rays or mosquito kissing. So which effect is better, physical shielding or chemical products?

Which effect is better, wearing long sleeves or wearing sunscreen?

Dr. Huang Yulin suggested that wearing hats, holding umbrellas, wearing long-sleeved clothes and applying sunscreen products must be used flexibly to achieve the best sunscreen effect. For example, although holding an umbrella to shade the sun, it is possible to reflect ultraviolet rays through the glass window or walking on the asphalt road. Therefore, in addition to wearing an umbrella and long-sleeved clothes, the back of the ear, neck, back of the hand or instep will still be exposed, and it is necessary to apply enough sunscreen to the skin of * * * to completely defend against ultraviolet rays.

Sufficient dosage is effective.

How much sunscreen is enough? The SPF of sunscreen products is measured by applying two milligrams of sunscreen milk per square centimeter. So in theory, if you want to achieve the SPF or PA defense rate marked on the bottle, you must apply such a dose. Dr. Huang Yulin explained in simple terms that a child's face needs the weight of about 5 yuan coins; If it is a woman with a small face, the usage may be 10 yuan coin; If you are a boy or a person with a big face, you should use sunscreen the size of a 50 yuan coin.

Do I need sunscreen to wear long sleeves?

In theory, skin that has been covered by clothes does not need sunscreen. However, the knitting density of clothes is the key. Dr. Huang Yulin pointed out that, for example, sweaters or woolen goods that girls like to wear have large gaps, and the sunscreen effect may not be so good. If you wear such clothes, it is recommended to apply a layer of sunscreen lotion. If you wear tightly woven clothes, you don't need to wear sunscreen. There is a simple way to judge the density of clothes. Put the clothes in the sun and check their light transmittance. If the light transmission is good, the sunscreen effect may not be ideal.

Can children use adult sunscreen?

Generally speaking, children and adults will choose sunscreen products separately. As mentioned above, children's skin is delicate and sensitive, so it is recommended to choose physical sunscreen products to reduce the probability of allergies. In addition, they will choose aquatic products that are not strong, easy to clean, and contain no pigments, spices and alcohol to reduce the possibility of skin * * *.

It sounds that sunscreen products specially designed for children are mild. Can adults use sunscreen for children? Dr. Huang Yulin said that this is a physical sunscreen with a slightly moist texture. If the adult's skin is oily, it may feel greasy and uncomfortable after application; Or choose a sunscreen that suits you.

Can wearing long sleeves prevent mosquito bites?

Wearing long-sleeved clothes outside can achieve a certain anti-mosquito effect, but the effect is not 100%. It is recommended to use anti-mosquito products on the skin. Not all long-sleeved trousers have the same anti-mosquito effect. Dr. Huang Yulin reminded two key points. First, the cuffs and trouser legs are designed into bundles, so that mosquitoes will not take the opportunity to bite; Second, the sleeves and trouser legs should be loose. If the clothes are too close to the skin, the mosquito mouthparts are about 2 ~ 3 mm long, and they can bite the skin through the clothes.

Is it effective to spray mosquito repellent on clothes?

Because anti-mosquito products want to prevent mosquitoes from biting the skin, Dr. Huang Yulin suggested using them directly on the skin to achieve anti-mosquito effect; If you just spray it on clothes, the effect will be greatly reduced. The Department of Disease Control of the Ministry of Health and Welfare also reminded that before using anti-mosquito products, you should carefully read the label instructions and use them according to the packaging instructions to avoid spraying them on wounds or mucous membranes such as eyes, nose and mouth. Children should avoid using it on their hands to avoid eating anti-mosquito ingredients by mistake because of contact with eyes, nose and mouth.
