1, how to protect skin by swimming in summer
Ultraviolet rays not only directly project on the skin and hair, but also do harm to the skin and hair through the reflection of water when you swim outdoors.
Dermatologists believe that ultraviolet rays and chlorine-containing swimming pool water are the enemies of hair health in summer. Long-term exposure to the sun's ultraviolet rays will lead to the loss of water on the hair surface, showing a dry, light color; Long-term contact with chlorine-containing swimming pool water will also make hair difficult to comb, and even destroy the surface tissue of hair, making hair easy to break, split and turn yellow.
In this case, the skin will be more seriously damaged than on land because of the high reflection of water on ultraviolet rays, and it is easy to dry and wrinkle because of the loss of water, which can also explain why many people find dandruff and fine lines on their skin after soaking in water for so long. There are also some special bathing products for swimming in the market. These products are said to be able to sterilize skin care, chlorine and bleaching powder, which is very suitable for people who often swim in the water.
2, the whole body high sun protection
Outdoor swimming pools and beach swimming need to apply high-efficiency sunscreen products. Because of the reflection of sunlight, the amount of ultraviolet rays absorbed by the skin in water will double. Therefore, we should not only choose sunscreen products with SPF30 above 30, but also choose sunscreen products with PA+++. This year, sunscreen products have been upgraded to pa+++ index, which is enough to resist the invasion of outdoor ultraviolet rays.
1. Apply sunscreen with waterproof function all over the body, and choose some oily sunscreen at most, which can prevent the sunscreen from being washed off after swimming for a long time. In addition, reapply sunscreen within two or three hours.
2. The strongest time of ultraviolet rays in sunlight is between 10 and 3 pm. It is best to choose swimming time after 4 pm, especially those who often work indoors. They are less exposed to the sun and are more likely to get sunburned.
3, sunscreen should not be too stingy, wipe out a layer of thickness to be effective, at least 0.05 cm, all over the body, at least one ping-pong ball at a time.
4. If possible, you can choose a sunscreen swimsuit, which has a certain sunscreen ability to the skin.
5. Apply sunscreen waterproof foundation on your face. Now, a new generation of summer foundation not only has sunscreen function, but also allows you to play with water without removing makeup.
6. Strong ultraviolet rays can make keratin in hair lose a lot of water. Wearing a swimming cap is the most direct and effective method. Without swimming cap, you can directly apply disposable hair care essence with sunscreen function to your hair.
3. How to care for the skin after swimming
After swimming, the skin will be dirty, mainly because of the water quality of the swimming pool. Because swimming venues are generally used continuously, it is difficult to guarantee the hygiene standards. The free residual chlorine in water with PH value is greatly reduced, the contents of ammonia, hydrogen and urea are increased, and bacteria such as coliforms multiply in large numbers, which increases the turbidity of water. In swimming pools, chlorine is often added or recycled to keep the pool water clean, which will increase the concentration of chlorine. At 2-3PPM, people will feel the obvious chlorine smell, and of course they will stick to their bodies.
In addition, swimming will inevitably bring skin excrement, shed hair, snot, sweat, body fluids, and even urine and swimsuit dyes and fibers into the water, so the body will be dirty after swimming.
After swimming, you should clean your body carefully, and you can use a bath like "swimming dew" to clean it. This product can help you get rid of fungi and bacteria, and has skin care function. In addition, it can remove chlorine odor and bleaching powder from your body after swimming, making your skin clean, smooth and moist.
In addition, you can also apply anti-chlorine emulsion before swimming. When this emulsion is applied to the body, it will produce a layer of isolation effect on the skin, which will isolate the skin from water containing too much chlorine, thus playing a role in protecting the skin and preventing the skin from feeling dry due to too much chlorine in the water.
4. Precautions for swimming in summer
1, people who are unwell, especially those with skin diseases, open wounds, gynecological diseases and reproductive diseases, are not suitable for swimming.
2. It is not suitable for swimming before meals, after meals, after drinking and after strenuous exercise. In addition, women's physiological cycle, menstrual period and ovulation period are also recommended not to swim.
Don't go swimming in places you haven't been to, especially those who choose outdoor swimming. Try not to go to deep water areas and places unfamiliar with geographical conditions. At the same time, if you want to go, you'd better swim with a partner who is familiar with water.
4. Don't inhale through your nose when swimming. If you feel drowning, you should immediately open your mouth and take a deep breath. Remember to breathe through your nose.
5. Don't fight when swimming. Usually, there will be many people swimming together. It is recommended not to fight during swimming, especially novices. It is best to take necessary precautions.
6. Wash your whole body with cold water before swimming to avoid discomfort and leg cramps. It is recommended to do some necessary warm-up exercises before swimming, so that the joints of your head, neck, shoulders, arms, legs and limbs are all active before swimming.
7. If you have cramps while swimming, don't be nervous at first. Stop swimming immediately, surface on your back and seek the help of your partner.
8. Drink light salt water properly before swimming to replenish physical strength.
9, swimming time should not be too long, because swimming consumes physical strength very quickly, if you soak in water for a long time, it is easy to have fatigue problems.
10, don't dive backwards. Some people think that diving backwards is very exciting, but they don't know that there are many hidden dangers. Both beginners and experienced swimmers should try not to try this swimming method.
1 1. If you are a child or a beginner, you'd better swim in the company of others.
12, don't eat immediately after swimming, it is best to rest for a few minutes and then replenish your physical strength, otherwise it will easily cause gastrointestinal diseases.
13, don't swim outdoors for a long time, otherwise it is very easy to cause sunburn, burns and even acute dermatitis.
14. If someone is found drowning, take measures as soon as possible. If you are a good swimmer, take off your clothes and shoes before you go into the water, approach the drowning man from the back and side, and then take him to a safe place by backstroke. Never let the drowning man hug you, or you may not be able to swim. If you are not a good swimmer and you are not sure that you can save each other, then I suggest you not to try to save people in the water. First, you can throw swimming rings or other floating objects at the drowning person. Secondly, you should call for help at once and ask for help from others. For drowning people, don't be nervous at the first moment of drowning, and try to get help from others. At the same time, if you are sure that someone wants to help yourself, you should pay attention to the rescue methods given by the other party and cooperate with the rescuers. Don't cling to each other, otherwise it's easy for both of them to drown.
