What are the benefits of the sea and sea water

Active research into the benefits and harms of the sea began less than 100 years ago. But even in ancient times, doctors prescribed walks along the sea coast to recuperate. The sea is not only healing water and a lot of entertainment. This is oxygen-rich air, sun-warmed sand and stones that burn the skin, polished for centuries. In the complex, it is the most powerful natural healer, which can be visited almost without restrictions.

The chemical composition of sea water

In all seas and oceans, the composition of water is almost the same, but the concentration of substances varies. So the Dead Sea is considered the saltiest, and the Baltic Sea is the most "fresh". In the classical sense, seawater is an oxygen molecule combined with two hydrogen molecules. But it is sea water that contains a huge amount of impurities.

These are mainly metal salts. It is estimated that 1 kg of liquid contains an average of 35 g of salt. That is why the extraction of table salt from sea water is developed in tropical countries. Here is a list of the elements that are present in the water:

• sodium;
• bromine;
• iodine;
• magnesium;
• potassium;
• fluorine;
• chlorine;
• calcium.

These are the main 8 elements, the ions of which are present in any seawater. Less than a century ago, German scientists found gold in the composition of water, albeit in insignificant amounts. The water of the oceans and seas contains the most chlorides and the least carbonates. This significantly distinguishes it from fresh river. And that is why the sea water tastes salty with bitterness.

The benefits of a seaside holiday

A seaside vacation involves close contact with natural healers. These are water, sand, air, sun and stones. Together, they have a unique effect on the strength of the impact on the external integument and internal organs of a person. It is not for nothing that health improvement at sea is considered so popular, and most importantly, effective.

Under the influence of external natural factors in the human body, many processes are activated:

• metabolism;
• skin regeneration;
• cleansing mucous membranes;
• stimulation of heart contractions;
• breakdown of cholesterol;
• oxygen saturation;
• lowering blood pressure.

The benefits of bathing in seawater are based on direct contact with the elements, and it is the body massage with waves that gives a positive effect. Under their light pressure, blood circulation and metabolism are stimulated in the upper layer of the skin. The bronchi expand and the depth of breathing improves - this is a good workout for the lungs and prevention of bronchitis.

2-3 weeks in the coastal zone allow you to strengthen the immune system, cleanse the mucous membranes of the upper respiratory tract, and lightly harden the whole body. Children are especially sensitive to this, who remain charged with solar and sea energy for many months after returning from the resort.

The benefits of sea air in saturating the body with ions of useful metals through the respiratory system and partially through the skin.This is a passive wellness that suits people with cardiovascular diseases, weakened by long-term illnesses or operations.

The benefits of sea water for the body

Purified seawater is now found in many medicinal and prophylactic nasal sprays and throat rinses. Its alkaline environment has a positive effect on the skin and especially the mucous membranes. It has been proven that regular swimming and diving for 2-3 weeks give a stable remission for sinusitis, rhinitis, tonsillitis and other diseases of the ENT organs.

Sea water, rich in salts, has antibacterial properties. Its components, upon systematic contact with mucous membranes and skin, kill pathogenic microbes and fungi. They are afraid of her ubiquitous staphylococcus and streptococcus - the main causative agents of inflammatory diseases of the nasopharynx. If fungus lives on the skin or nails, sea baths will help get rid of them or achieve a stable remission.

Bromine is a natural sedative, regulates the transmission of nerve impulses, reduces emotionality and nervousness, and gives a good sleep. Iodine is useful for the thyroid gland, both for the prevention of pathologies and for maintaining normal functioning. Calcium is responsible for the strength of teeth and bones, the normal functioning of the immune system.

The sea for children is an opportunity to partially cope with vitamin deficiency, weakened immunity, chronic diseases of the ENT organs. Through the skin and nasopharynx, sea water nourishes the skin cells with oxygen, increases hemoglobin, and helps to eliminate toxins and toxins. If you alternate sand baths with sea baths, the healing effect increases significantly.

Sea water treatment

Thalassotherapy - this is what the official medicine calls sea water treatment. This method of recovery is used in all seaside health resorts. The benefits of the sea for the human body is a comprehensive health improvement that covers all systems and organs. Diseases for which treatment with sea water is indicated:

• metabolic disease;
• obesity, cellulite;
• psoriasis, dermatitis;
• allergy;
• sinusitis, vasomotor rhinitis, sinusitis, adenoids;
• tonsillitis, pharyngitis, laryngitis;
• depression, irritability, neuroses;
• asthma, bronchitis, pneumonia;
• arthritis, arthrosis, osteochondrosis;
• rheumatism;
• gynecological diseases.

It is believed that salty sea water is more active on the body when it is heated to body temperature. It is these baths that sanatoriums offer their patients. A greater effect is achieved by combining water heating with a hydromassage or shower.

An active jet of water produces a massage effect. Thanks to this, the skin heats up, the pores open, and beneficial trace elements enter its deep layers. From there, through the blood vessels, they go to the internal organs, bones and joints.

The hydromassage procedure is especially useful for people with problems in the work of the musculoskeletal system or those who have suffered injuries or surgeries. In this case, sea water stimulates the healing processes of wounds and scars, and also activates the restoration of the integrity of the cartilage. The benefits of swimming in the sea, although not as high as in the shower or in the hot tub, also have a good effect, especially when combined with heating sand baths.

Purified and heated seawater is used to wash the sinuses in case of sinusitis and rhinitis, seawater relieves inflammation of the mucous membrane and in case of allergies. In case of chronic diseases of the ENT organs, it is also recommended to rinse with sea water every day for 1-2 minutes 5-6 times.

Sea water is also good for weight loss.When bathing, all metabolic processes are activated, from the skin to the blood flow. Thanks to this, the processes of burning fat and breaking down cholesterol are triggered. The main thing is not to make up for the lack of energy spent while swimming with sweet buns.

Hardening is another healing effect of seawater. Its temperature in the world's oceans varies depending on the region, but is always lower than body temperature by more than 10 ° C. With regular water procedures, blood vessels are trained, which narrow and expand under the influence of contrasting temperatures. In addition, the body increases its adaptive capacity. Best of all, this hardening is reflected in children's health.

Sea water for skin

Problem skin reacts positively to sea water. For the effect to be visible, baths must be regular. After bathing, they do not immediately go to the shower, but allow useful minerals to be absorbed into the skin. Sea water is good for skin and hair due to the following properties:

• disinfects;
• saturates with oxygen and minerals;
• improves microcirculation of blood in the surface layers of the skin;
• regenerates;
• promotes tanning.

With acne, acne, acne, they dry out, inflammation disappears, wounds from old rashes heal. The antibacterial properties of the water prevent the growth of pathogenic microbes, which protects the skin from repeated breakouts.

With atopic dermatitis of an allergic nature, sea bathing is also useful. When combined with sunbathing, a long-term remission is achieved. New rashes do not appear, but old ones heal.

Seawater increases the production of melanin, the pigment that provides tanning. In moderation, it is beneficial and protects the skin from burns.

Walking along the seaside

Walking along the coastal area is also good for your health. The main thing is to do it right. Firstly, walks are performed barefoot, alternating entry into the water with a walk on the sand. Secondly, it is important to choose areas of land with sand and pebbles. Thirdly, do not interrupt walks for 2-3 weeks, regardless of the weather.

During walks, blood oxygen saturation increases, blood circulation and heart rate normalize, lymph accelerates. Through the respiratory system and partially the skin, ions of useful metals enter the body, which reduces the concentration of free radicals and their negative effect on humans. Walking on sand and pebbles activates points on the feet, which are responsible for the work of internal organs.

Walking is useful for absolutely everyone, but it is especially valuable for people with nervous disorders and cancer.

Why sea air is useful

The first, and most important, how the sea air differs from others is its purity. There is no dust, gases, slags in it. Active oxygen, ozone and seawater particles make it very useful for children, people with respiratory diseases and allergy sufferers. The sea air cures asthma, bronchitis, helps the lungs to recover from pneumonia.

It is best to walk and breathe the sea air at the very edge of the water no further than 200 meters. Here the air is saturated with the smallest particles of water. This is almost a healing aerosol that moisturizes and disinfects mucous membranes. This air is good for the skin as well.

Breathing is useful not only when walking or swimming. Actively increases the level of health by taking a nap in the fresh air under a canopy. At this time, the heart rate is normalized, the blood pressure level returns to normal, and the immune system is strengthened.

Benefits of swimming in different seas

The benefits of swimming in the sea is to activate the work of muscles and all internal organs. But due to the peculiarities of the chemical and ionic composition of water in different water bodies of the world, the degree of this benefit is different. To understand where it is better to recover, you can study information about the seas from experts.

Black Sea

It differs from other seas in its high content of hydrogen sulfide in the water and moderate salinity. The Black Sea health resorts are the best place for the treatment of bronchopulmonary diseases and allergies. Hydrogen sulfide has a positive effect on the cardiovascular system. Regular bathing strengthens the lungs, normalizes the heart rate, and tones the blood vessels.

The Dead Sea

Even those who have never been able to swim here swim. The highest concentration of salt is in the Dead Sea. Water contains a lot of bromine, iodine, potassium, iron, chlorides and sulfates. People with skin diseases such as psoriasis, eczema, dermatitis come here.

In addition, sea water, combined with therapeutic mud, enhances metabolism and blood circulation. The high concentration of bromine soothes the nervous system. For the treatment of the musculoskeletal system, they also go to the Dead Sea.

Azov sea

The muddy bottom of the Sea of ​​Azov is a storehouse of 92 microelements. The water here is especially rich in iodine and bromine. People come here with metabolic disorders, pulmonary diseases, problems in the work of the endocrine system. Swimming in the sea helps to restore the functioning of the nervous system.

Mediterranean Sea

The composition of sea water is almost identical to the Black Sea. Swimming in its waters improves lung function and normalizes blood pressure. It is useful to visit the resorts of the Mediterranean Sea for people with vegetative dystonia, asthma, bronchitis.

Baltic Sea

The coolest of all the other seas. Its coast is a pine forest, and the air of the coastal zone is saturated with phytoncides. Swimming in the sea helps to harden and strengthen the immune system. It is useful to take sea baths for people with pulmonary diseases and problems in the cardiovascular system.

the Aegean sea

Has an average salinity, optimal temperatures during the holiday season. It is useful to swim here for people with diseases of the heart and blood vessels. The condition of hypertensive patients and everyone who suffers from vegetative-vascular dystonia noticeably improves. As in all seaside resorts, asthmatics are healed here.

Swimming rules in the sea

In order for sea water and air to bring only health benefits, you need to know some rules for healing. They boil down to the implementation of the following recommendations:

• you can plunge into the sea in 1-2 hours after lunch and cannot be on an empty stomach;
• the optimal time is from 10:00 to 12:00 and from 14:00 to 20:00;
• long distance swims are done after preliminary rest;
• do not dip after prolonged exposure to the sun, you need to sit in the shade for 20 minutes to avoid heatstroke and cramps;
• for hypertensive patients and people with heart disease, long swims are prohibited; short dives or passive water baths are useful for them.

Swimming in the sea should be combined with walking on stones and hot sand baths, then the healing effect will be complete.

Harm to the sea

The sea itself cannot significantly harm human health. In most cases, he himself is to blame for the deterioration of health. Harm of sea water can be expressed in hypothermia, allergic rash, burns, hypertensive crisis and loss of consciousness. This happens when the basic rules of behavior in a new climatic zone are not followed.

Exceptions are cases when a person is unaware of the presence of an allergy to sea water. It manifests itself as hives on large areas of the skin, a rise in temperature is possible. Sometimes a person learns about the pathologies of the thyroid gland only when visiting the resort.

Sea air for a child can also be dangerous in the case of infectious diseases of the bronchopulmonary system. Exacerbation of the disease with bouts of bronchospasm is possible from the influence of salts. People with sensitive skin and disorders in melanin synthesis are susceptible to burns, this is also taken into account when visiting a resort.

Who is contraindicated in the sea vacation

Not everyone can go on vacation to the sea. Here is a list of those conditions and diseases that are an obstacle to visiting the sea coast:

• exacerbation of chronic diseases;
• ulcers and abrasions on the skin, weeping wounds;
• increased body temperature;
• dry and irritated skin;
• kidney disease;
• phlebeurysm;
• hyperfunction of the thyroid gland;
• herpetic eruptions;
• stage 3-4 hypertension.

Being at sea can worsen the condition of people after a stroke, heart attack or undergoing surgery on internal organs. Any climatic fluctuations are contraindicated for them. In the presence of infectious diseases, a trip to the resort is also contraindicated. Water and sea air are good for the baby. But there are children who react sharply to fluctuations in iodine, which causes them a serious allergy. The sea will only harm such a category of young vacationers.

Conclusion

The benefits and harms of the sea are two components of a summer vacation. The degree of effectiveness of healing procedures largely depends on their competent organization. Proper rest will charge you with health for the whole season until the next vacation, which means that visits to doctors will only be preventive.
