Experts of the World Health Organization are constantly warned: "melanoma (skin cancer) participation, for the thinned ozone layer is no longer protected, as before, the earth from ultraviolet rays.
Their intensity has increased, and that provokes the emergence and development of melanoma. " Hence it is necessary to draw the appropriate conclusions: to protect the body and especially the eyes from direct exposure to UV rays, while relaxing on the sea is not "fry" in the sun to a "tobacco chicken", sunbathe in the shade or under an awning.
Ultraviolet rays - is not wrong, as long as we treat them as a healing process that is taking metered.
That's when the ultraviolet show all its useful properties: antibacterial, and vitamin-erythemal action.
The bactericidal effect is manifested in the ability of ultraviolet rays at a certain dose of radiation to kill pathogens. Ultraviolet rays cause the production of vitamin D, which is required to maintain normal muscle, nervous system, bone apparatus.
Finally, erythematous or pigmented effect of ultraviolet rays is their ability to induce skin reactions - erythema (redness) and pigmentation (tanning). Approximately 77% of people at the same time the sun's rays and cause erythema and pigmentation.
These people have a pink, normally-functioning skin. The second group of about 9% includes people with pale skin who have a skin reaction occurs only in the form of erythema - skin only red, but tan in the conventional sense of the word.
Perhaps, in the best position are the third group of people (about 14%) that quickly tanned in the sun, while their skin is never red. Great value when sunbathing have a combination of the air temperature, its humidity, wind and atmospheric pressure, as well as individual sensitivity to solar radiation and overall health.
When choosing a place on the beach should be borne in mind that the tarmac themselves absorb a lot of heat, and creating favorable conditions for the formation of a stream of hot air, can turn an ordinary bath into a hot sunny dry air.
Previously it was thought that the best time for sunbathing by the sea - the morning (8.00 am), when the sea breezes have a cooling effect, and rock, sand or gravel least running high.
In the morning hours in air less water vapor and more ultraviolet rays. But now, due to the thinning of the ozone layer and increase the flow rate of ultraviolet rays, prolonged exposure to the sun in the morning is not recommended.
It is best at this time to walk on the beach in bright light clothing, a hat and sunglasses, and not to lie on the beach. Avoid sweating and be sure to wipe dry after bathing, as wet skin is more susceptible to burns.
Going on vacation, especially in the hot region, it is also desirable to consult your doctor to know whether you can sunbathe and what dose of ultraviolet radiation is safe for you.
Generally in normal physical condition heliotherapy healthy.
With the help of improved mechanisms of the autonomic nervous system, increases the body's resistance to infections and colds, increases efficiency. As a preventive, heliotherapy means tempering can be assigned to all healthy people.
Especially it is necessary to those who live in the northern parts of the country, or in large industrial cities. Heliotherapy shown for all the manifestations of hypovitaminosis D, with a number of skin diseases (hypodermis, certain types of psoriasis), weak healing wounds, ulcers, fractures, chronic diseases of the musculoskeletal system.
With age, sun baths should be taken less often, their duration should be much smaller and direct radiation should be completely excluded. It is necessary to watch closely for the response of the child's body to the impact of solar radiation.
If the child becomes lethargic, moody, irritable if he loses appetite and sleep disturbance, it is necessary to immediately stop sunbathing.
Of course, totally unacceptable stay many hours with young children on the beach under the scorching sun. Children are encouraged to sunbathe just under an awning or beach umbrella.
Heliotherapy contraindicated in all diseases during exacerbations, bleeding, exhaustion, malignant and benign tumors, progressive forms of tuberculosis, atherosclerosis, angina, hypertension,
bronchial asthma with frequent severe attacks, in violation of the endocrine glands, functional disorders of the nervous system, blood diseases, lupus erythematosus, malaria, increased sensitivity to sunlight.
