Sunbathing and solar hardening. Sunlight treatment and sunbathing rules
“The sun, like a dear mother, will never offend you.” This saying puts the sun and mother on the same level, and one cannot but agree with this. The sun, really, like a mother, will both praise us and scold us. Will render beneficial features on ours, but also, with strong love, it can cause harm. The sun always makes us happy, we miss it on winter days, we wait for spring to come, then summer. The holidays will come, and it will be possible to sunbathe a little under the bright and warm sun.
Doctors do not advise staying under drugs for a long time bright sun, especially in the afternoon. All these walks can result in a burn or heatstroke. Children suffer more severely from such complications. But this does not mean at all that you need to give up sun exposure. So that our joy is not darkened, we need to know what pros and cons we gain from our love for this “hot” planet.
The benefits of the sun and sunbathing
The most noticeable benefit from the sun is the regulation of our daylight hours, or in scientific terms - the sleep cycle. Sunbathing gives us vitamin D. It is known that this component comes to us through food ( chicken eggs, butter, Cheddar cheese, cream, powdered milk whole), but for it to transform, chemical transformations are needed. Under the influence of ultraviolet radiation on our skin, a group of vitamins - ferols - is activated, as a result of which calciferol is produced, known to us as vitamin D. This useful element regulates the absorption of many minerals and is involved in the metabolism of phosphates and calcium. All these actions normalize the functioning of the kidneys, intestines, parathyroid glands, stabilize the skeletal system, skeleton, prevent osteoporosis, have an impact on us antibacterial effect.
Ultraviolet radiation itself also helps us and, when used in small doses, can be beneficial. It heals small wounds, dilates blood vessels, which leads to high-quality blood circulation. It has a beneficial effect on the condition of the skin - acne disappears, becomes elastic and healthy. Do not avoid sun rays, because every time you expose your skin, you receive ultraviolet radiation, thereby producing a pigment in the body that can scatter and absorb these rays. And by getting a tan, your skin shows that you are provided with protection from radiation.
The radiation cannot be seen with the ordinary eye; it is outside the range of the spectrum we can see. But science has proven that it has three divisions - A, B and C. Two of them act harshly on us and can harm us. These are rays B - they “work” in the middle of the day, so it is not advisable to walk between 12 o’clock and 15-16 o’clock; group C - mostly climbers are familiar with it - it acts high on mountain tops and is considered very harmful; Ray A, which occurs in the evening, is considered the softest and most harmless. In this regard, it is best, and healthier, to sunbathe in the evening, after 18 o’clock, less problems and the skin color turns out beautiful and even.
In medicine, this ultraviolet light is used in cosmetology (note that during frequent drying with a UV device, when doing nail extensions, you can get skin), dentistry (it is harmless for the patient, but doctors need to be careful), dermatology. The device created by physicists uses light to treat severe forms of tuberculosis, psoriasis, and pustular diseases.
Harm from excess sun
As a rule, the damage from sun rays that we encounter most often is burns on our body. They appear because we forget ourselves and spend a long time under the sun, and then pain and burning sets in, and we notice redness. Areas of skin begin to peel off. These are all signs sunburn. Our skin is divided into five phototypes, and each of them has its own perception of ultraviolet radiation. Light-colored people are at risk. They have skin phototypes 1 and 2 and the sun's rays are the most dangerous for them, it dries out their skin, signs of premature aging appear, and they are destroyed. useful material, proteins. Staying in the sun puts them at risk of developing diseases such as melanoma and skin cancer. These are blondes, they can also include redheads, light-eyed, often with freckles.
Also, the sun may cause harm to the eyes and brain. In the first case, from exposure to sunlight on our vision, we can get a retinal burn. Best protection- This Sunglasses, which is an important accessory in winter and summer. The cause of heatstroke is exposure to the scorching sun with your head uncovered. Symptoms - heat(40-41 g), nausea, headache, possible loss of consciousness. Sometimes, heat stroke can be fatal.
From all of the above, we see that vitamin D plays a significant role in many processes in our body. By avoiding the sun and hiding from ultraviolet rays, we may experience a lack of this vitamin, which will lead to a decrease in immunity.
We all dream about summer, plan trips to the sea... To make a walk on the beach bring you a good mood, the editors of the website gomer.info advise you to drink more fluids, avoid standing in the sun, apply sunscreen to your skin, determine your skin phototype, use hat, umbrella. Do not forget that sunbathing is best taken in moderation, but we have just discussed the benefits and harms of the Sun! Remember that during treatment and when taking medications, a drop can be medicine, and a spoon can be poison? This is exactly what happens with sunbathing!
Sunbathing treatment is practiced as an alternative medicine method for healing a variety of ailments. Moreover, sunbathing is used to obtain a beautiful, even tan. Of course, when practicing heliotherapy, it is important not to overdo it. Otherwise, instead of benefit, sunlight will only bring harm, and painful burns will form on the skin.
Sunbathing and health: the benefits of sunlight
Heliotherapy (from the Greek gelios - “sun”, therapeia - “treatment”) is one of the most available methods healing taken into service traditional medicine back in ancient times. This is a method of treatment with sunlight and heat, that is, the use of the radiant energy of the sun for therapeutic and prophylactic purposes.
How is sunlight beneficial for the body? Its impact is multifaceted. Sunbathing gives health: they activate blood circulation and work, strengthen the nervous system, improve the supply of organs and bones, which helps strengthen them.
Benefit sunlight Another benefit for health is that the rays stimulate, stabilize blood circulation, dilate blood vessels, and improve elasticity. After sunbathing, the heart rate increases, blood flow to the skin increases, its color and condition improve. Moderately bright sun helps to get rid of it - after a short stay in the light, brain activity improves.
As you can see in the photo, sunbathing provides the skin with a pleasant tan:
What other benefits are sunbathing and what does solar energy affect in the body? The sun, combined with swimming in the sea or river, or lying on the warm sand, helps relieve joint pain. Solar energy affects sperm production: Sexual activity increases in summer. People who rarely get sun exposure are at greater risk of developing cancer.
It has been noticed that in the summer it is much more... The fact is that the properties of sunlight, combined with increased physical activity, increase metabolism.
What are the benefits of sunbathing and who are they contraindicated for?
Another benefit of sunbathing is that under the influence of the sun, vitamin D is formed in the skin, on which the normal development of bones and teeth depends. Lack of sun is especially harmful for children: They may develop rickets, a disease that causes deformation of the bones, especially the legs.
You should not lie motionless under the blinding sun, you need to move more - run, exercise, exercise, without allowing the body to overheat.
Because vitamin D serves building material for bones, osteoporosis, which causes brittle bones in old age, most often affects those who lead a sedentary lifestyle and rarely spend time in the sun. With a lack of sunlight, hair loss, nail splitting, and many other health problems can occur.
Contraindications to sunbathing: severe heart defects, acute inflammatory infections, nervous system, pulmonary tuberculosis in active form, intense headache. Solar radiation is contraindicated for malignant and benign neoplasms.
There is a risk of getting uneven skin pigmentation and worsening well-being in the sun during pregnancy. Doctors do not advise sunbathing after taking certain medications. Substances with photosensitizing (increasing sensitivity to light) properties contain perfumes and other perfumes. Therefore, on the beach it is better to refuse cosmetics; you can use specially created preparations for summer use with special sun protection factors, which are indicated in the composition by the letters SPF.
How and when is the best time to sunbathe?
Without the sun, which is a source of heat and light, life on Earth is impossible. Our body is affected by both visible light and solar rays, as well as invisible to the eye - infrared and ultraviolet. These rays are absorbed differently by different layers of the skin. During the transition from ultraviolet to infrared radiation the depth of their penetration increases.
Sunlight works wonders: it gives energy, helps to heal the most various diseases, improves mood and appearance person.
The mechanism of exposure to sunlight on humans is well known. The fact is that as a result of metabolism, free radicals are formed in our body - compounds that harm the entire body and contribute to its aging. They destroy genetic information in cell nuclei, promote the formation of atherosclerotic plaques on the walls of blood vessels, and make these vessels fragile. Melatonin, a special hormone whose formation is promoted by sunlight, can stop the negative “activity” of free radicals. It is he who plays the role of a kind of protector, since he intercepts and destroys free radicals, thereby maintaining overall well-being and pushing the aging of the body far into the future.
How to sunbathe outdoors? As a rule, they are beneficial for many diseases, but in order not to harm your own body, you must follow certain rules.
When is the best time to sunbathe to avoid getting sunburned? It is recommended to do this an hour after a meal, and finish the procedure no later than an hour before a meal. The safest sunbathing in the summer is from 8 to 11 a.m., and in the evening from 4 to 6 p.m.
Only by following the rules of sunbathing can you get a lasting and beautiful tan - darkening of the skin under the influence of ultraviolet radiation, as a result of which melanin is deposited in its surface layers.
Duration of sunbathing and first aid for burns
On the first day, the duration of sunbathing in direct rays should be no more than 5-10 minutes. On the second day, sunbathing can be increased to 15 minutes. After this, you should increase your exposure to the sun by 5 minutes every day, bringing the procedure to 50-60 minutes, but staying in the sun for more than 2 hours a day is not recommended.
Children under 12 years of age must be in the shade of trees during the procedure. For this age group Solar procedures should begin with 2-3 minutes and gradually increase to 30 minutes. Children over 12 years old can be in the open sun, and the duration of the procedure at the first stage is usually no more than 5 minutes, gradually increasing the time to two hours. After sunbathing, you need to swim, shower or shower cold water and rest in the shade for half an hour.
If you stay in the sun for a very long time, you are likely to get a sunburn. Urgent first aid is needed when the skin becomes dry, painful, slightly swollen and red. At the first negative signs, you should immediately take cover in the shade, cool the damaged areas of the skin under a cold shower so that the pain subsides. Then take an antipyretic, treat the burn site with alcohol or a special ointment such as Panthenol. If the burn is severe, consult a doctor.
Traditional medicine for sunburn recommends lubricating sore spots with sour cream, fermented baked milk or yogurt. A good remedy is a mixture of equal parts of alcohol (cologne) and vitamin A solution.

That the sun, air and water are ours best friends, is known to every child. Summer is the only time of the year when all these three factors, in combination with each other, have a complex effect on our body, making it healthier. About the healing effect fresh air We already talked about it in one of the episodes of “The Family Doctor”. Today we will talk about the sun, or more precisely, about sunbathing - heliotherapy.
SUN'S rays are essential to the human body. With the wise use of the life-giving energy contained in them, we can strengthen our body, harden it and even cure some diseases. After all, as special studies have shown, the sun, when dosed correctly, effectively heals the body.
Sunbathing contraindicated for malignant and benign neoplasms, as well as for cardiovascular diseases. People with thyroid diseases, liver disease, anemia, leukemia, and skin diseases should not stay in the sun for a long time. In addition, prolonged sunbathing can lead to overheating, skin burns and heat stroke.
The energy carried by the sun's rays spreads in the form of special waves, which, like sound waves, have different lengths. Infrared rays constitute up to 45-50% of solar radiation falling on the earth. Under the influence of these rays, blood flow to tissues increases.
Infrared radiation has anti-inflammatory, metabolic and vasodilating effects. It is useful for chronic and non-purulent inflammatory diseases internal organs, burns and frostbite, slowly healing wounds and ulcers, diseases of the peripheral nervous system (myositis, neuralgia), consequences of injuries to the musculoskeletal system.
Ultraviolet radiation is divided into three components: long-wave, medium-wave and short-wave. Ultraviolet long-wave irradiation causes pigmentation, or tanning of the skin. Under the influence of these rays, the body's immune system is stimulated and its resistance to harmful environmental factors increases.
Such training of the immune system is especially necessary for people who are weakened chronic diseases. Indications for this type of irradiation are also chronic inflammatory diseases of internal organs (especially the respiratory system), diseases of the joints and bones, burns and frostbite, poorly healing wounds and ulcers, eczema, seborrhea, fatigue. Lichen squamosus (psoriasis) responds well to treatment when exposed to ultraviolet irradiation.
At the same time, excessive and uncontrolled ultraviolet radiation leads to skin aging and can cause cell mutation, that is, subsequently lead to malignant neoplasms. Contraindications to long-wave irradiation: benign and malignant tumors, cardiovascular diseases, acute inflammatory-purulent diseases, liver and kidney diseases with severe dysfunction, increased sensitivity to ultraviolet radiation.
When irradiated mid-wave ultraviolet rays superficial layers of the skin, the provitamin contained in it is converted into vitamin D3 - necessary component phosphorus-calcium metabolism in the body. In the kidneys, vitamin D3 regulates the excretion of calcium and phosphate ions in the urine. Calcium accumulates in bone cells with the help of this vitamin. If there is not enough of this element in the body, mental performance decreases, the excitability of the nerve centers increases, calcium is washed out of bones and teeth, and blood clots worse. If there is a lack of vitamin D3 in a child’s body, children lag behind in development.
The reactions that occur when irradiated with medium-wave rays of the ultraviolet spectrum stimulate the activity of almost all body systems. Mid-wave ultraviolet radiation is useful for inflammatory diseases of internal organs (especially the respiratory system), consequences of wounds and injuries to the musculoskeletal system, diseases of internal organs (pneumonia, bronchitis, gastritis), rickets, metabolic disorders, diseases of the nervous and muscular systems (neuritis, radiculitis), bones and joints, and skin diseases.
Shortwave ultraviolet radiation has a high bactericidal effect. It is very useful for wounds, cuts, skin diseases (abscesses, pimples), purulent inflammation. Like other types of radiation, it is contraindicated for malignant and benign neoplasms, and cardiovascular diseases.
Sun rays are divided into direct, oblique, diffuse and reflected. The influence of straight, vertically incident rays is most powerful. Oblique rays pass through the atmosphere longer distance and therefore have a weaker effect on the body. Scattered rays are formed when sunlight passes through clouds and tree foliage; their effect is even weaker. The reflected rays of the sun represent daylight.
Staying in direct sunlight for too long is not only not beneficial, but, on the contrary, can be fraught unpleasant consequences for the body. To prevent sunbathing from harming the body, there are basic rules.
You need to exercise self-control using your own feelings. If severe redness and pain appear on the skin, you should stop sunbathing to avoid severe burns and overheating of the body and lubricate the affected areas of the skin with a special after-sun cream or fermented milk products, which will have a tonic effect, relieve redness and inflammation of the skin, and also reduce the temperature bodies.
The time spent in the sun depends not only on the age and physical condition of the body, but also depending on skin type. Dark-skinned people are least at risk of sunburn, since their skin contains more pigments that protect against sun exposure. But those with fair skin should stock up on UV protection products in the form of creams and emulsions before going out into the sun.
It is best to lubricate the skin with a special one before sunbathing. tanning product. Similar products - milk, oil, gels - are produced by all reputable cosmetic companies. Moreover, the method of their use and the principle of action are the same: they are applied to clean skin half an hour before sunbathing. Each product has a so-called coefficient - the degree of protection from sunlight. By multiplying it by 15 (15 minutes is the time it takes for unprotected skin to burn), you will find out how much time you can spend under the sun without fear of getting a sunburn.
For those who have not yet tanned and people with sensitive fair skin, it is better to use a product with a high degree of protection (25 or 30), and for dark-skinned and already tanned people it is better to use a product with a lower degree of protection (10-12) or an intense tanning product. It is important to remember that any tanning product can be easily washed with a towel and washed off with water. Therefore after water procedures it needs to be reapplied.
In principle, a special sunscreen can be replaced with any baby cream or nut butter (just not Vaseline!). The oil is also suitable for softening the skin after sunbathing. If the skin is still burnt, a simple old remedy will help: spread the burned areas with thick sour cream or cream, pre-warmed to room temperature. And keep in mind that until your skin stops hurting, you will have to give up beach pleasures.
Despite the fact that, as already mentioned, sunbathing is an excellent prevention of rickets, children should take it with extreme caution. First of all, this concerns children of the first three years of life.
Children of the first year of life are usually taken out into diffused sunlight (this is the so-called chiaroscuro), where the babies receive light-air baths. The temperature in the shade should be at least 23 degrees. The duration of light-air baths for children in the first half of life is from 3 to 10 minutes (this time increases gradually). In the second half of the year, the duration of the baths can be increased by 5 minutes once every 4 days, bringing them to 30 minutes. A course of light-air baths consists of 25-30 procedures.
A child over one year old in the summer should walk on a playground that has equal parts of continuous shade (better from greenery than from canopies) and chiaroscuro ("lace" shadow from tree leaves). Begin taking light-air baths at an air temperature of at least 20 degrees in the shade. In the future, when the child gets used to it, baths can be continued at a lower temperature (15-16 degrees), but in this case outdoor games are organized.
The duration of the first light-air bath is 5 minutes. Then, increasing the duration of the bath by 5 minutes once every 3-4 days, bring total time procedures up to 1 hour.
Taking light-air baths on hot days, a child can overheat even under scattered sunlight. Therefore, during a walk in the summer, you need to give your baby water more often and monitor his general condition. In this case, the child must be dressed so that the clothing protects his body from overheating. The first signs of overheating are facial redness and profuse sweating. In this case, the child is immediately taken into the shade and given something to drink.
Here are some recommendations only for women. When sunbathing, they are advised to protect their skin from exposure to ultraviolet rays, which can cause dangerous changes in the fibers on the surface of the skin. connective tissue. As a result, the skin becomes dry, loses its elasticity, its ability to bind liquid decreases, and as a result, wrinkles form.
The sun is especially dangerous for the forehead, nose, and earlobes. The rays fall almost vertically onto these areas, and the skin instantly gets burned. If this does happen, apply a lanolin mask to the burnt skin.
It is not recommended to use decorative cosmetics while sunbathing. You can only paint your lips to protect them from drying out. In this case, it is advisable to use rich lipstick. Better yet, use this an old remedy: dissolve a pinch of henna in a spoon of warm vegetable oil, then carefully apply the mixture onto your lips with a brush, and wash off after 15 minutes. As a result, your lips will acquire an extraordinary coral shade that will last for two weeks.
Don't forget to “feed” your skin twice a day with hydrating gels and nourishing creams. And no lye soap! Only products with a neutral or slightly acidic reaction.
It is advisable to sunbathe while relaxing in nature or while doing physical exercise in the most revealing clothing. While sunbathing, try not to lie still for the entire time allotted for this procedure. Summer requires activity and movement. It’s good to play volleyball, badminton, swim more often. Enjoy your summer holiday!
Solar energy affects sperm production. Scientists have found that in summer, sexual activity in men increases noticeably. In addition, the sun's rays can charge a person with vigor and lift his spirits. It has been noted that in the summer people are much less likely to become depressed, smile more often, and are more cheerful and friendly.
The sun's rays have a healing effect on the entire body. Blood circulation and the work of the heart muscle are activated, strengthened nervous system, physical activity increases, and the supply of calcium to organs and bones improves. The sun helps produce vitamin D in the body, which is called the vitamin of life.
The Swiss August Rollier, who called himself a heliotherapist, maintained a “solar hospital” in the Swiss Alps and treated tuberculosis, colitis, anemia, gout, atherosclerosis, asthma, skin diseases. At the same time, Rollier used only two remedies - sunbathing and herbs saturated with the energy of sunlight. He argued that the higher the dose of solar radiation to a plant, the better the treatment.
