Pools with sea water
In most cases, it is not always possible to often visit the sea and be treated in salt water, but this is now an alternative. Currently, many hospitals, sanatoriums, sports clubs and health centers offer to visit the pool with sea water. Occupations in salt water are not only useful, but also profitable - the pool will cost less than a trip by the whole family to the sea.
In recent weeks, there have been four cases of children with a drowning picture. Like almost the majority of those who visit. "I can hardly think of the children who drowned on the beach, but in the pools they come to me quite a lot in a short time," admits the doctor, who believes that this is because on the beach, since the child is embarrassed while he will not reach the sea at a height where he can drown, "pass a few minutes," while in the case of the pool it is a matter of a second. In addition, there are a lot of people on the beach, "he adds.
Bonet admits that it is "unclear" how long the child's brain can go without oxygen without irreversible damage. But it's enough to make the minute go by. It happens very quickly, "says the pediatrician, who insists that brain damage is the main danger of these cases: The brain is what is most quickly damaged, and there is no recovery. When he gets hurt, everything fails, "he says.
Choose a pool that meets the following criteria:
- Location near the house;
- Average mineralization of water (3-4 g / l);
- The swimming pool is covered and equipped with cleaning equipment.
Types of pools
Modern basins almost completely recreate the microflora of the sea in terms of the composition of the liquid. They are divided into the following types:
Aspiring water Another child was sent to Son Espazes, because he sucked in water and suffered "bilateral pneumonia", that is, he had both lungs. You never know whether there will be something very aggressive in the next few hours, which will further damage the lungs. You may need a respirator or, as it happens, you will recover in a few days without further effort, "he explains. The third also quickly recovered. In the fourth, which occurred this week, the girl could not be revived.
Drowning can lead to brain death: "if you stop the artificial respiration system, the baby will die" - or other damage - "it depends on the affected part, will be the consequence or others." He explains that the only difference between drowning in the sea and in the pool is a type of pneumonia that a child can suffer if he has aspirated water: Fresh water has no salt and tears the cells, it destroys them. With salt water, on the contrary, having salt, sucks water from the cells, dries them.
- Open (installed outdoors, open-air);
- Indoor (the basin of the pool is located inside the room or covered from above by a roof).
An indoor pool requires less energy for heating, wind is not collected in it, garbage is brought, but such a tank requires additional equipment to ensure air circulation. You can buy a small indoor pool and install it at the cottage.
And he adds that these are various ailments, but both are "rather complicated" and ultimately lead to the destruction of the lungs. "In addition, neither the pool water nor seawater is clean, they have bacteria," says Bonet, who points out that this complicates the clinical picture. Of course, he emphasizes that it is easier to swallow water in the pool than on the beach: "With seawater many times there is a spasm of the glottis, and it does not enter." The doctor asks the family that if the child suffers from a small drowning and they think that they could suck the water, they should take it to the doctor. "If they have doubts, let them come," he insists, although he insists that if a small coughing occurs, he becomes aware and plays, if later he has a fever and cough, "this will not be anything sharp."
Benefits from the sea
The effectiveness of the use of salt water is enormous: it helps the body to heal and harden the body. During the reception of sea baths, the circulation of lymph and blood is improved, harmful substances are released from the body.
Everyone knows that water from the sea depths has a powerful effect on the human body. This is due to the fact that the composition of the plasma of human blood is close to the composition of water in the sea, therefore, being in the sea, the body literally restores the loss of minerals, saturating the body through the skin. This explains the pacification and relaxation that we feel when we are in the water. In it, the body becomes lighter, the muscle tone of the body decreases, the puffiness decreases.
Pablo Dies, responsible for emergencies and emergency situations of the Red Cross, asks the family to take precautions when they go to the beach with children or when they are near the pool. And not only with small, but also with people who do not know how to swim well, those who have problems with mobility or the biggest. "These are the three risk groups, the most vulnerable," he says. In any case, there is a real danger in the act of bathing. Whether it's in the sea, in the pool, the river or the lake, "says Dees, who warns that most people" underestimate "the risk that this entails.
Also, the salt water has a mild massage effect on the skin and human organs. It is difficult to overestimate the benefits of exposure to sea air and salt water on the body. It consists of more than 26 trace elements, among which there are iodine, magnesium, sodium, fluoride, potassium, bromine and so on. There is an effect on the cardiovascular, respiratory, nervous system of a person, decreases allergy, eczema, itching, improves metabolism.
Mucus and blows He does not distinguish the dangers between the beach and the pool: In the sea there are currents. Water reaches your knee, and in a second you have a shoulder. In addition, this ensures that most people "do not know about their limitations or their family group". He stresses that there are risks in the pool, such as misses and blows that do not exist on the beach.
This reference in emergency services believes that everyone, especially those who have a pool at home, must undergo a first aid course. "Knowing the basic methods of cardiopulmonary resuscitation can save lives," he insists, before asking them to install an anti-slip surface in the vicinity. In addition, remember that you can not lose sight of children "not even a second". Neither in the pool, nor at sea.
It has a beneficial effect on the skin of the face, strengthens the tissues and muscles of the body. Many say that after the resorts tight flabby skin is pulled, there is a natural stimulation of cell regeneration.
After swimming, it is necessary to wash off the salt, wipe the body dry with a towel and apply the cream, as it dries the skin.
How to create an indoor pool with salt water?
To relax in the salt water and get a helping of health do not necessarily go to the sea. To do this, you can simply organize a seawater pool at home. This requires two components: salt and special equipment. It should be remembered that salty sea water is an aggressive environment for metals and many other materials, so it is necessary to purchase special equipment that is not afraid of corrosion.
In the latter case, he asks families with small, elderly or disabled people to be "near the watchtower", because this is the "safest" area. On the beaches controlled by the Red Cross, in Santa Eulária, there are two guards on the tower. One in it and the other that walks along the shore, "explains Dees, who emphasizes that when they know that there will be a children's walk to these beaches, they increase vigilance.
The head of rescuers asks the family not to rely on floats and hoses. "You can not delegate them, they help you stay on the surface, but the float can turn around," warns Diz, who stresses that this summer they already had to intervene in several rescue situations at sea. Some of them are doubled, the last one from grandfather and his granddaughter. During the season, many parents leave children responsible for grandparents who take them to the beach to mitigate the heat. "Let them come close to the tower," he repeats.
Salt
How much salt you need depends on your preferences and the availability of medical contraindications, but for an approximate orientation, you can cite the mineralization data of natural reservoirs. This indicator is measured in ppm, that is, the amount of salt in grams dissolved in 1 liter of liquid is indicated.
Over time, salt should be added, but, as a rule, not more than 1 time per month. The percentage of mineralization is reduced because the water in the indoor pool is gradually replaced by fresh water when the pure water is added.
Tips for the safety of children in water
For their part, parents should not allow their protection to be at any time. Vacations in the pool or at sea are favorites of children, but there are some dangers. Avoid bathing in the hottest hours, apply sunscreen after each bath and protect the child with sunglasses and a hat. The bathing area is not a nursery, and parents bear the primary responsibility for the safety of their children. If they are group holidays, adults should share the task of caring for two or three children each. Sleeves or float: the basic rule, children who do not know how to swim, are safer with sleeves than with a float. With a float around the waist, if the child is turned upside down, you will not have the strength or the ability of the psychomotor to stand up straight. And, as for the vests, they often go up and stay around the head. Another advantage of the sleeves: the balance in the water is better perceived. Do not get into the water, not wet: the body, overheated by the sun, when it crashes into cold water, can suffer from a hydro-resistor, that is, with a cardiopulmonary arrest. That's why it is necessary to wet the neck of the neck, hands and feet and slowly enter the water. Tips for swimming in the sea: you should swim only in certain areas. You should also follow the flags: with orange, and even more so with red, it is better not to go to the beach. Access to the private pool should be provided with a barrier that closes it. And an adult should never leave the edge of the pool, not even take the phone. When the bathroom is finished, all toys and floating objects must be removed so that the children do not want to catch them. Even in the inflatable pool you should watch the little ones. Give him the confidence: the more comfortable the child will feel in the water, the less he will allow himself to panic if a problem arises. To do this, you need to play with it, gently splash, teach it little by little to raise your head under the water and explain that you need to close your mouth under water. When you swallow the water, you have to smile and congratulate him. Floating relaxed, next to an adult, is within reach of the smallest and is the first step to swimming.
- Sleeves are needed.
- Beware of thermal shock: the baby's skin is especially delicate.
- You should bathe with them and not lose sight of them.
Remember that salt is a natural preservative, therefore, due to this property, the development of microflora in water slows down. This fact also affects the period of use of water, increasing the period of its replacement.
Equipment.
To equip a pool with sea water, technically more expensive equipment is required than for a conventional pond. The reason is that the concentration of salts causes corrosion, therefore, it is more often necessary to change the filters, and the contacting elements must be covered with a special composition. It is better that the elements are made of bronze. This metal is perfectly preserved in salt water.
To maintain water resistance, do not press the buttons of the device under water.
- The water in the pool with a high content of chlorine and sea water is very conductive.
- Problems often arise when measuring the heart rate in water.
The following equipment is needed for the pool:
- The pump is a filter unit made of cast iron or bronze. And if you want to install attractions, slides, then stock up additional pumps. This may not be very cheap, but it fully justifies itself.
- To heat water, heat exchangers with a casing made of titanium will be required, and electric heaters must be equipped with a heating element made of titanium. With regard to mortgages, they can be chosen from stainless steel or bronze. A cheap version of mortgages is made of clay plastic.
- It should be borne in mind that for the disinfection of water can not use a large amount of chlorine as in conventional pools, because because of this all the benefits of salt will be reduced to zero. Use the cell for disinfection. It converts salts dissolved in water into chlorine. Do not be afraid of chlorine in this case, because such a concentration is not harmful to salt water, but it will affect the microflora and bacteria.
- You can also purchase equipment based on ultraviolet radiation or ionizers based on silver or copper.
Children's pools
Children stay in seawater should last no longer than one hour. It is also very important to wash off all salt after visiting the pool.
In the watch industry, water resistance is usually indicated in meters, which means static water pressure at this depth. Each Polar device that has an indication of water resistance has been checked before delivery to make sure it withstands water pressure. Polar products are divided into four different categories depending on water resistance. Keep in mind that these definitions may not apply to products from other manufacturers. When performing underwater activities, the dynamic pressure created by movement in the water is greater than the static pressure, which means that moving the product under water leads to greater pressure than if the product were stationary.
Unfortunately, we can not always allocate time and money for a trip to the sea. But this problem can also be solved by building a pool with sea water, which has a beneficial effect on health. The realization of such an idea is an excellent alternative: own sea near the house. Salt water contains the necessary substances: zinc, iodine, manganese, phosphorus, copper. Sea water helps to renew the blood composition and stimulates the functions of organs, promotes rejuvenation.
In the basins it is important to ensure that there is little chlorine in the water, because, according to the Spanish Society of Pneumology, a high level of chlorine can cause asthma in children. And if you decide to go to sea, look for beaches that have been awarded, which are given for the quality of water and services on the beach.
How long can a child stay in the water? Children under the age of one year quickly lose body heat, so it is not recommended for them to take a bath for more than 10 minutes, especially if the water is cool. If you are older, you will see their needs; In any case, if you notice that you have goose lips and lips lost their pink color, it's time to remove them.
What is the sea water in the pool? Are there any benefits in the seawater pool? Seawater in the pool is saline water that does not contain marine microflora and does not affect so positively as real sea water. Then the question arises: how does salt water disinfect water? One of the main components of the salt is sodium Na and chlorine Cl. The most effective decontaminating agent is active chlorine Cl, which is obtained in electrolysis plants - cells or as they are also called chlorine generators or chlorinators. When saline water passes through the electrodes of the electrolytic cell under the influence of electric current, Na +, Cl-, OH- and H + ions mix and form NaClO sodium hypochlorite, which, when reacted with H2O water, forms HClO hypochlorous acid and nitrite.
Is it recommended for a child to use floats? The main risk they present is that the child turns and stays with water immersed in water. The float should be viewed more like a water toy if you have not chosen a type of farm with an anti-roll system.
Inflatable cuffs and life jackets are a very good option, although the only thing that is absolutely safe is the absolute vigilance of children when they are in or near water. Even if your child knows how to swim, do not trust yourself: the most amount of quenching occurs 6 months after the child has learned to swim.
Hypochlorous acid promotes oxidation and destruction of bacteria, and also kills viruses. The recommended salt concentration in the pool is 3-4 g / l. that is 9 times less than in sea water. To achieve the required concentration in water, it is necessary to dissolve about 5 kg per cubic meter or 1000 liters. Thus, salt is needed only for the production of chlorine in the course of the reaction occurring in the cell.
Chloramines, which create a sense of the smell of bleach, are destroyed during their passage around the electrodes and produce chlorine, which will be used anew. The electrolyzer is installed in the water treatment system of the pool water after the filter installation and water heating. It is controlled by a microprocessor control unit.
There are two types of electrolysis plants on the market. The first: for the electrolysis process to be possible, a little salt is added to the water. After passing through the electrolyzer, free chlorine forms and the water remains salty, so to speak, marine; the second: salt is poured into the cell and chlorine is formed in the electrolysis cells. In both cases, salt is consumed slowly and add or replenish it should not be more than once a month, or even less. The concentration of salt in water can be measured with a special device for measuring the salinity of water.
The main thing: water treatment with electrolysis increases the pH of the water. It is necessary to combine the electrolyzer with the metering pH adjustment pump, which will allow to adjust and adjust automatically the pH level of the water of your "sea".
Advantages of electrolytic cells, which are described by many companies:
- - simplicity in operation;
- - Chlorine transportation is not required;
- - there is no loss of activity of the disinfecting properties of the reagents;
- - environmental Safety;
- - high reliability of bactericidal action;
- - water is softer;
- - there is no irritation and dry skin;
- - automatic cleaning of electrodes;
- - There is no smell of chlorine.
Despite a number of advantages of "sea" water, there are some nuances: pumps and embedded elements of water treatment should be made of bronze, and heat exchangers of titanium. This significantly increases the cost of building a pool with sea water. It should also be remembered that when installing a flow-through cell (the salt is dosed into water), it is not possible to apply alternative treatments, it is necessary to adjust the salt concentration in manual mode. In the case of using an electrolyzer with a salt backfill in it, we note that the cost of such plants is higher than the cost of the complex - an automatic station based on chlorine and an ultraviolet plant that lowers the concentration of chlorine to a minimum dose, makes the water crystal clear, and it does not irritate the skin and does not smell of chlorine . So it is worthwhile to weigh the pros and cons of choosing a pool with sea water!
