Description
There are attempts in many circles to convince everyone that sunbath- This is a complex and extremely risky procedure that can only be used by a person technically trained in the laboratory or a doctor. When reading an ordinary book on sunbathing, one definitely gets the impression that sunbathing is difficult and also very dangerous. There are so many warnings and so many procedural details to follow, so many times and conditions for avoiding sunbathing, that it's very easy to give it all up in disgust and forget about sunbathing altogether. But there are many claims with commercial overtones. Anyone with enough common sense to be able to sleep, exercise and breathe fresh air can take a sunbath. This bath is as natural as the named treatments.. The ritual used by Dr. Rollier and the other doctors does not make sense. They start by exposing one leg for a few days, then the other, then both legs, then the thigh, then the abdomen, chest, and finally the back. All this ceremony is unnecessary. In my opinion, Rollier is too cautious at the beginning of sunbathing and delays the process after the patient has acquired a good tan.There are a few simple precautions to be taken when sunbathing, and anyone of average intelligence can understand and apply them. For those who have never sunbathed, the following are especially needed: precautions.
Sunbathing is completely different from the common practice of enjoying fresh air. Taking a sunbath without clothes. Care must be taken not to burn the body. The rule should be "better too little than too much". Blondes and redheads should be more careful than brunettes and dark-skinned races.
It is necessary to start a sunbath with exposure of the whole body from six to ten minutes daily and gradually increase the exposure time from half an hour to an hour or more, even up to three to four hours. But time increase slowly. Expose the front exposed part of the body to the sun for three to five minutes, then the exposed back side of the body for three to five minutes. Increase the time each side is in the sun by one minute daily and up to half an hour for each side of the body. Although I often find even this pace too fast and have to slow it down considerably, I don't think it should be scrupulously followed by healthy and active people.
A person lying in a solarium can more easily abuse a sunbath than someone who is messing around on the beach. I also believe that there is more benefit from exposing the back to the sun than the stomach, I cannot prove this now, this is my personal theory.
All you need is natural protection.
Usually strongly insist on sun protection of the head and eyes. But this bad advice. A person does not need glasses and caps just like animals. Sunlight is very beneficial for hair and eyes. It has always amused me to hear sunbathers recommend covering their heads and then hear from them about the amazing results of hair growth from UV radiation. It is well known that sunlight enhances hair growth, and more head exposure can easily reduce the number of bald people through similar baldness prevention. I've been bareheaded for over fifty years in most of Texas under the tropical sun and it doesn't hurt me today. My patients do not cover their heads while sunbathing without being harmed by it. The eyes also benefit from light, and harm from too much darkness. It was found that with poor eyesight, looking directly into the sun brings great benefit. Fish found in dark water caves are always blind. Mules working in underground mines have a great visual impairment, which mules working on the surface of the earth do not have. Men working underground and children living in dark cellars are always very sensitive to light. Both need sunlight, and prescription of dark glasses and safety glasses can only worsen their condition. But this is exactly what doctors and ophthalmologists constantly do, who are constant only in one constancy - to approach everything is wrong. Dr. R. A. Richardson wrote in Psychology (1929): “During my recent trip to Africa, I took the opportunity to find out whether cataracts and blindness, often observed there, are caused by intense sunlight and heat, as I've been told before. To my surprise, I found that the people who were blind from cataracts were among those who did not work for outdoors, but in small shops and in the bazaars of Tunisia. When questioned, I concluded that the cause of their eye disorder was an excessive infatuation with proteins, sugars, starches, nicotine and coffee.
The eyes themselves are not sensitive to light, eyelashes are sensitive to light, which causes them to close when strong sunlight falls on them. Of course, they close to protect the eyes, and we should fully appreciate the significance of this fact by opening our eyes to the light. This is the only cover required for eyes in the sun. Sunglasses for "eye protection" are absurd. In fact, they make the eyes more sensitive to light and damage vision. Squinting is not necessary and no safety goggles are needed to prevent it. You can look directly at the sun in the afternoon without squinting. The development of wrinkles around the eyes is an indicator of thoughtlessness. Any need for glasses and creams will disappear if you just stop squinting. Squinting doesn't do any good.
With regard to sunbathing, there is an objection to the so-called "drying damage" that is allegedly done to the skin. But this is a consequence of overheating in the sun. rather than sunbathing, if reasonably taken. This is where the manufacturers of lotions and "natural ointments" can be expected to emphasize the vices of "overdoing" by not distinguishing between the abuse of sunlight and its proper use to sell their wares.
But doctors should know better. Facial lubrication creams, lotions and ointments are completely unnecessary for those who have enough intelligence to behave correctly. There is no need to lubricate the skin to prevent dry skin. Dry skin indicates overexposure to the sun. Lubricating the body with olive oil before sunbathing prevents some of the ultraviolet rays from reaching the skin and is therefore not recommended. This seems to be a very old practice, since in ancient times baths with ointments were taken. If sunbathing are taken correctly, then there is no need to lubricate the skin with ointment after it. Excessive sun exposure makes the skin dry and flaky. If you don't get carried away with sunbathing too much, it will leave the skin soft and properly lubricated with its own fatty secretion. If "protective" doses were really as effective as they say, they would interfere with the benefits of sunburn. There is no excuse for being in the sun for so long that the skin becomes dry and hard. Why abuse what we do? An intelligent person does not need any ointment to replace natural lubrication, for he has no guilt for the abuse of excessive exposure of his skin to the sun. The purpose of sunbathing is not to see how much you can burn yourself and even more so become black from a tan, but to supply your body with the right amount sunlight. They also object that sunburn destroys the fine structure of the skin. But what has this objection to do with intelligent sunbathing? It's stupid to get sunburned. There is no reason to let yourself get burned while sunbathing. Due care regarding the duration of the sunbath will always prevent burns. Man of sense will tan gradually and will always avoid burns by all means. Only stupid girls stay in the sun so long that they destroy their skin. Others will change the ointment offered for sunburn for reason. People who can't sunbathe without getting burned belong to the same category of people who can't eat without overeating. They are out of control and without self-discipline. They tend to abuse everything.
This question seems to be strange. But in fact, knowing what time is best to sunbathe, you can get a much more even, lasting and attractive tan. Otherwise, the chocolate shade will come off very soon, or even worse - painful burns will appear on the body, and the burnt skin will subsequently peel off in a layer.
What is the best time of the year to sunbathe?
It's another one interest Ask. But if you figure out how to sunbathe properly, it becomes clear that in reality there is nothing strange about it. The point is that in ideal prepare for the beach season should be in advance. That is, in order to start thinking about what time it is better to sunbathe in June, it is advisable to take sunbaths in May or even at the end of April. It will also be useful for the skin, and you won’t have to feel like a black sheep on the beach (in every sense of this expression).
In the spring, the rays are very soft and it is rather difficult for them to harm the skin. But they will be able to perfectly prepare the epidermis for an intense tan. Before the start of summer, it is recommended to walk as much as possible in the open sun or spend several sessions in. At first, let only the hands and face burn. A little later, if the weather allows, you can afford to undress to a swimsuit. It is not necessary to lie under the sun. On the contrary, it is much better to sunbathe during active sports - playing tennis or volleyball, running.
At what time of day it is better to sunbathe in the spring, it is difficult to say. Many people prefer sunbathing with morning exercises. And it’s not scary if it can’t be done on the street. Open the window on the balcony and work out here. Of course, this is less efficient, but still.
When is the best time to sunbathe at sea?
At local resorts, you need to sunbathe in the morning and in the evening, and the most “dangerous” sun is from 11 am to 5 pm. This period of time is better to sit out somewhere in the shade. And do not rely on beach outfits to protect you from. Lightweight fabric passes enough to burn, the amount of ultraviolet radiation.
What time of the day is best to sunbathe on the beaches of hot countries? About the same. But you can't spend too much time in the sun at once. On the first day, solar procedures should generally last no more than five minutes. Every day the time spent in the open sun increases.
Do not forget that while swimming, the tan is also taken. Moreover, it happens much faster. Water refracts the sun's rays, so many of the vacationers burn out while swimming.
How to get an even and lasting tan?
To get an attractive tan, you need not only to know what time is best to sunbathe. You should also follow a few simple rules:
- Before going out into the open sun, it is undesirable to use body cosmetics, splash with toilet water or perfume.
- Be sure to use protective body creams.
- When sunbathing, the position should be changed every ten minutes.
- Immediately after returning from the beach, you should rinse in the shower and apply some kind of moisturizer to the epidermis.
- When you get out of the water, do not dry yourself with a towel. Droplets of water contribute to a faster tan. But be careful: this makes it much easier to get burned.
Few people believe this, but the diet during the beach season also affects the quality of the tan. The skin is more likely to turn chocolate if eaten:
It is very useful to drink a complex of vitamins before going to the sea, which must necessarily contain ascorbic acid.
Procedures involving the use healing properties air and radiant energy of the Sun for the purpose of healing and hardening. V. and s. V. form the basis of climatotherapy. They are an essential element a dignity. - hens. treatment. They can be used in everyday conditions (on the recommendation of a doctor).
Air baths. Fresh air affects the whole or partially naked body; form air baths is the so-called verandah treatment, which consists in a long stay on open verandas; while patients are dressed in accordance with the season (in cold weather they use warm blankets sleeping bags). Freely moving air during air baths, irritating the nerve endings of the skin, improves breathing and oxygen saturation of the blood. At the same time, the intensity of oxidative processes increases and the muscular and nervous systems are toned, the body's thermoregulation systems are trained; appetite increases, sleep improves. Especially useful air baths in areas where the air contains an increased amount of oxygen, it is saturated sea salts, light air ions, etc.
Air baths are prescribed by a doctor. They are recommended to strengthen the body, especially for children, increase resistance to adverse effects. environment(see. Hardening of the body), as well as in a number of diseases, in particular in tuberculosis of the lungs and other organs, with anemia, with functional diseases nervous system, certain cardiovascular diseases, etc. Contraindications: acute febrile illnesses, exacerbations of rheumatism, chronic. inflammatory diseases of the joints, neuritis and myositis.
Air baths can be warm (t° above 22°), cool (*° 17-20°) and cold (° below 17°). The course of air baths begins at an air temperature above 20 °; the duration of the procedures at first is 10-15 minutes, then they are increased daily by 10-15 minutes. and bring to 14 / g - 2 hours. Cool baths are first taken for 3-7 minutes, then their duration is increased daily by 3-5 minutes. and bring to 25-60 min. When taking air baths with an air temperature below 17 °, light physical exercises should be performed. exercises to avoid hypothermia. Cold air baths are recommended for trained people, their duration should not exceed 7-20 minutes. Air baths should not be taken until you feel chilly or goosebumps. The time spent outdoors during veranda treatment is 2-3-6 hours, sometimes it is advisable to stay on the veranda around the clock.
Sunbathing. Compound sun rays and their effect on the human body is heterogeneous. Solar radiation consists of visible (light), as well as infrared and ultraviolet rays invisible to the eye. Light rays act Ch. arr. on the retina of the eye, causing color sensations, which is necessary for the perception of the surrounding world. Infrared rays, penetrating into the tissues of the body and having a thermal effect, increase the temperature of the irradiated skin area. Ultraviolet rays have a complex biological action (see Sunburn).
Sunbathing is used as prescribed by a doctor for a number of diseases of the skin, joints, sciatica, neuritis, tuberculosis of bones and joints, etc. respiratory tract etc. Sunbathing is contraindicated in acute diseases, exacerbation of chronic. lung diseases, went. - kish. a path, etc. Solar baths can be the general (irradiation of all body) and local (irradiation of a part of a body). During irradiation, the total radiation of the Sun is used, which is made up of direct exposure to sunlight, diffuse radiation (in the shade, without exposure to direct sunlight), reflected from the walls of the building, the surface of the earth, water, etc. Diffuse radiation (from the blue sky) contains less UV rays than direct, and is more gentle. Exposure to the sun (direct radiation) of healthy adults begins with 5 minutes. and, gradually adding 5 minutes, bring to 40 minutes, taking into account general state, fitness and degree of hardening. With scattered radiation, baths are taken initially for 10 minutes, increasing the duration of the procedure to 1-2 hours. in warm weather. Sunbathing should be taken lying on a couch or sitting in a deck chair, exposing the sun to different sides of the body. It is advisable to take an air bath before sunbathing. In case of direct radiation, it is necessary to cover your head with an umbrella or shield. To protect the eyes, dark glasses should be used (the mucous membrane of the eyes - the conjunctiva, which does not have a protective stratum corneum, is more sensitive to radiation than the skin, and its inflammation may occur). It is not recommended to sunbathe on an empty stomach, immediately before and after meals. Finish the sunbath with a rest in the shade, after which you can swim or take a shower. Directly after swimming, sunbathing is not recommended. In people weakened after certain diseases, the sensitivity of the skin to ultraviolet rays is increased. Often such hypersensitivity is observed in northerners, people who are forced to spend most of the day indoors, adolescents, the elderly, pregnant women, and especially young children.
Children should be especially careful when sunbathing. The head of the child must be protected by panama; when the heat sets in, children should not be immediately exposed: at first they should walk in shorts and light shirts, then in shorts and a T-shirt, and only then in shorts and panama. In order to prevent overheating and excessive ultraviolet radiation, it is necessary to periodically alternate exposure with rest in the shade (see Toddler age, preschool age). The action of ultraviolet rays is stronger in the south, in the mountains. Northerners vacationing in the south should sunbathe in the morning, and it is better to start sunbathing in a sparse shade under a cellular canopy or on cloudy days when the ground reaches Ch. arr. scattered solar radiation. IN middle lane and sowing areas best time for sunbathing from 11 am to 1 pm. People aged 55-65 years are recommended exposure for no more than 20-30 minutes, people over 65 years of age should avoid exposure to direct sunlight. They are more useful air baths in the shade until 11 o'clock. in the morning or after 4-5 pm. Ultraviolet rays in a moderate dose cause an even skin tan.
Excessive exposure to radiation adversely affects the body, causing sunburn skin, sometimes with necrosis, heat stroke, irritability, fatigue, headaches, insomnia, fever, exacerbation of certain diseases. V. and s. V. take in summer time on the beaches, where special canopies are arranged over the trestle beds, in solariums, aerosolaria located in parks, on the banks of the river, reservoirs, on special verandas. IN winter time in resorts for air baths, insulated climate pavilions are used, and for sunbathing - verandas covered with a special film that transmits ultraviolet rays. see also
“The sun, like a mother, will never offend” This saying put the sun and mother on the same level, and one cannot but agree with this. The sun, indeed, is like a mother, and will praise us, and may scold us. Will render beneficial features on our body, but also, with strong love- bring harm. The sun always makes us happy, we miss it on winter days, we wait for spring to come, then summer. Holidays will come, and it will be possible to sunbathe a little under a bright and warm luminary.
Doctors do not advise to spend a lot of time under the bright sun, especially in the afternoon. All these walks can end with a burn or heat stroke. Children are more susceptible to these complications. But this does not mean at all that you need to abandon the sun's rays. So that our joy is not overshadowed, it is necessary to know what pluses and minuses we get from our love for this “hot” planet.
Benefits of the sun and sunbathing
Everyone notices the benefits of the sun, is to regulate our daylight hours, or speaking scientific language- sleep cycle. Sunbathing gives us vitamin D. It is known that this component comes to us with food ( chicken eggs, butter, cheddar cheese, cream, whole milk powder), but for it to transform, chemical transformations are needed. ultraviolet radiation, the group of vitamins - ferols is activated, as a result of which calciferol is produced, which is familiar to us under the name - vitamin D. This useful element regulates the absorption of many minerals, participates 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, and have an antibacterial effect on us.
In itself, ultraviolet radiation 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, healthy. Do not avoid the sun's rays, because every time you expose your skin, you get ultraviolet, thereby, the body produces a pigment that can scatter and absorb these rays. And by getting a tan, your skin shows that you are protected from radiation.
The radiation cannot be seen with the ordinary eye, it is outside the zone of the spectrum visible to us. But science has proven that it has three divisions - A, B and C. Two of them act hard 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 the tops of mountains, it is considered very harmful; Ray A is considered the softest and most harmless, which happens in evening time. In this regard, it is best, and more useful, to sunbathe in the evening, after 18 hours, less problems and skin color is beautiful, even.
In medicine, this ultraviolet is used in cosmetology (note that during frequent drying with a UV device, when building nails, you can get skin cancer), dentistry (it is harmless for the patient, and doctors need to be careful), dermatology. Created by physicists, the device, with the help of light, treats severe forms of tuberculosis, psoriasis, pustular diseases.
Too much sun damage
As a rule, the damage from the sun's rays that we encounter most often is burns on our body. They appear from the fact that we forget and for a long time spend under the sun, and then comes the pain and burning, notice the redness. Areas of skin begin to peel off. These are all signs of sunburn. Our skin is divided into five phototypes, and each of them has its own perception of ultraviolet radiation. Light people are at risk. They have 1 and 2 skin phototypes and the sun's rays are the most dangerous for them, they dry their skin, there are signs of premature aging, they are destroyed. useful material, squirrels. Staying in the sun threatens them with a disease - melanoma, skin cancer. These are blondes, they can also include redheads, light-eyed, often with freckles.
Also, the damage of the Sun to the eyes and brain may appear. In the first case, from exposure to sunlight on our vision, you can get a retinal burn. The best protection- This Sunglasses, which is an important accessory in winter and summer. The cause of heatstroke is exposure to the scorching sun with uncovered head. Symptoms - heat(40-41 gr.), nausea, headache possibly loss of consciousness. Sometimes, heat stroke can be fatal.
From all of the above, we can see that vitamin D plays a significant role in many processes in our body. Avoiding contact with 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 of summer, plan trips to the sea... So that a walk along the beach will bring you good mood, we and the editors of the site www.site advise you to drink more fluids, do not stand under the sun, apply sunscreen to your skin, determine your skin phototype, use a hat, an umbrella. Do not forget that sunbathing is best taken in moderation, but we have just considered the benefits and harms of the Sun! Remember that during treatment and when taking medication, a drop can be medicine, and a spoon can be poison? This is exactly what happens with sunbathing!
The sun's rays are vital to us. We all know that under their action, the body produces vitamin D, which is so necessary for strengthening bones and increasing immunity. But, in addition, the sun gives us the hormone of happiness - serotonin, and the sun is also needed for its formation. And the sun helps to reduce pressure, prevents the formation of blood clots.
And at the same time the sun can be ours worst enemy: dry skin, premature wrinkles, sunburn, sunstroke and even skin cancer - all this also causes solar radiation.
In order to get the maximum benefit from the sun and not harm your health, you need to know how to sunbathe properly.
How to sunbathe
Taking sunbathing, you must follow some rules.
- Sit in the shade for about 10 minutes before going out into the sun.
- You should start with 5 minutes: 2.5 minutes for the back and chest. Increase the amount of time you spend in the sun by 5 minutes each day. The maximum time spent in the sun is 1 hour.
- Lie down with your feet in the direction of the sun and do not forget to periodically turn over.
- Do not sleep or read in the sun. You may not notice how long you sunbathe and get sunburned.
- It is not necessary to sunbathe lying down. If you are moving: walking, boating or cycling, the sun's rays also affect you. At the same time, they fall at a smaller angle and their action is softer, which reduces the risk of sunburn.
- The best time for sunbathing is morning before 11 am and evening after 4 pm. In the sun, try not to go out into the sun.
- Do not sunbathe immediately after eating, but being in the sun on an empty stomach is harmful.
- If you have fair skin, it is better to sunbathe not under the direct rays of the sun, but under a canopy or umbrella.
- Use a protective cream that matches your skin phototype. If you swim, then apply the cream every time you get out of the water.
- Don't forget the headdress.
- Be especially careful when sunbathing near the water and in windy weather. You can easily and imperceptibly get burned.
- After sun exposure, don't go straight into the water, sit in the shade for a few minutes.
Sunbathing for the elderly
For some reason, there is an opinion that it is harmful for older people to be in the sun. In fact, the opposite is true. Scientists have found that the more time older people spend outside in sunny weather, the lower their risk of osteoporosis, cardiovascular disease and diabetes.
Only when exposed to the sun should the elderly be careful, especially if they have high blood pressure or they suffer ischemic disease hearts.
It is better for older people to take sunbathing not in the open sun, but in its scattered rays: under an umbrella, in the shade of trees.
Sunbathing for children
It must be understood that the skin of a child is very sensitive to solar radiation, and the younger the baby, the stronger the effect of ultraviolet rays on it.
Pediatricians do not recommend sunbathing in direct sunlight for babies under one year old. They are suitable for air baths in the open air, but in the shade in calm weather. The temperature should be above 22 degrees. The duration of the first baths should be 1-2 minutes, then the sessions are gradually lengthened and brought up to 30 minutes.
Sunbathing should begin in diffused sunlight: under a light canopy or lacy shade from trees, then you can go out into the open sun. Remember that the baby's head should be in the shade. Be sure to protect the child's head with a panama hat, a scarf with a visor, a hat with a brim so that the sun does not enter the eyes.
What is the duration of the baths? First take the child out in the sun for 1-2 minutes, after 2 days add a minute. The maximum time spent under the sun is 10 minutes. After this, the baby can be doused warm water. If you notice that the child is overheated: the skin is reddened, he is naughty or, on the contrary, has become lethargic, take him to the shade and let him drink.
Sunbathing is best done in the morning, before 11 am. Do not sunbathe at temperatures above 30 degrees.
Who benefits from sunbathing?
Due to the fact that the sun promotes the synthesis of vitamin D, sunbathing is useful for diseases and conditions such as:
- osteoporosis - vitamin D is essential for bone strength;
- caries - the sun is the prevention of caries. Scientists have found that children living in southern countries are less likely to suffer from this disease;
- age-related decline in vision - vitamin D slows down age-related macular degeneration of the retina;
- menopause - studies have shown that women who are rarely in the sun (less than 1 hour per week), menopause occurs 5 years earlier than those who constantly tan. In addition, during menopause, the development of osteoporosis begins, so women are shown sunbathing during this period.
The sun increases metabolism, and due to this it is useful for people suffering from obesity.
Under the influence of sunlight, the production of testosterone increases, so doctors recommend that childless couples spend their holidays in warmer climes.
The rays of the sun dry and disinfect the skin, so sunbathing has a beneficial effect on skin diseases - neurodermatitis, psoriasis, acne.
Increased production of serotonin in the sun reduces the manifestations of depression. This is confirmed by the fact that in southern countries people suffer from depressive disorders less often than in the north, where the sun is a rare visitor.
To whom the sun is contraindicated
Sunbathing contraindications are:
- cardiovascular diseases with impaired blood circulation;
- oncological diseases;
- organic lesions of the central nervous system;
- significant sclerotic changes in blood vessels;
- increased sensitivity to solar radiation;
- active pulmonary tuberculosis.
