The solar light produces infrared beams (heat), visible light (color), ultraviolet (GRAPE, UVB) that there produce the bronze-colored one and the cellular changes that they predispose to the cancer. This radiation is major between 10 of the morning and 4 p.m. At these hours the level of radiations UV is major and more aggressive and carcinogenic. How long a day can we be to the sun without running risks? What aptitude to brown become does our skin have?The bronze-colored one is a mechanism of defense of the skin, since he exercises an effect of filter of beams UV. The exhibition to the sun in normal skins must be realized increasing 10 minutes of exhibition every day, from the first one that must not exceed 15 minutes, avoiding the hours of the midday. To 10 days the skin will be prepared to support the sun without problems except those of accumulation of solar radiation (important to prepare the leather cancer). It is necessary to bear in mind that type of skin has each one: the red-haired ones and the blonds it has very little aptitude to tolerate the solar radiation; the chestnut-trees it can be considered that they have a normal tolerance, and those of dark skin tolerate major speed in the capture of the sun. Must we always use solar protectors? Of what protection factor? Every how long do we apply them to ourselves?The factors of solar protection only offer an increase in the tolerance time to the solar beams (especially for beams UVB), but in fact they can allow to take a normal life. They are demonstrated useless in wide bogeys of action and to leak beams GRAPE and visible light (except the Avene 60). In these cases it can be effective the filters by means of titanium dioxide. The protection factors must apply 30-45 minutes to themselves before the exhibition begins to the sun, being eliminated by the perspiration and the water. The protection indexes are the factor for which it is necessary to multiply to know how long it protects us, example: A protection factor 20 allows to exhibit to the sun 20 minutes as if 1 minute was alone. The filter 50 allows 50 minutes as if it was 1. We will be able to find filters from factor 2 up to factor 50 or more that they are called entire or screens. Since age the children can sunbathe? How must they take it? Is it a "crime" to take a baby to the beach?The newborn babies and the minor babies of 5 months must not be exhibited to the sun. Up to three years with a lot of care. The biggest of this age have to of be exhibiting to the sun, since he is a vitamin producer D, but an intense broceado must not be exhibited and especially to burns, it leaves the skin much predisposed to cancer in the adult, his skin is much more fragile to modifications for the solar radiation. Always with solar filters. The solar radiation accumulates and his carcinogenic effect is accumulative with the age... Not to forget the topic of the dehydration for the heat! Is good to sunbathe during the pregnancy?The problem in the pregnancy with the sun is the appearance of solar spots what is called a Cloasma, which appears in the face and usually does not yield after the pregnancy. Must the women who take the birth-control pill have major care with the sun?It is a medicine called photopoisonous, that is to say that produces major absorption of the solar radiation and only for areas what there produces the cloasma or the spots of white coffee, very badly tolerated esthetically. With the wet skin, if we are in the beach or the swimming pool, there increases the risk of burning usThe water increases at least 10 % the absorbed beams, does an effect magnifying glass, in addition to which it sweeps the effect of the solar protectors. In a cloudy day or we even being to the shade can burn ourselves because the beams ultraviolet are reflected in the soil (snow, sand, grass, water...) and they reach our skin: no?The clouds leak the infrared beams and those of visible light but not the UV, for it the apparent protection effect is an enemy, it is not hot so... and it is not like that. The clear surfaces, sand, snow are very reflecting and they increase the solar radiation, taken care. If we have given ourselves some cream or perfume: also must we be specially careful with the sun?The cosmetics with perfumes produce solar spots for the photopoisonous effect, the sun has to of taking with the clean skin and with protective filters, nothing more. What care or precautions must be had by the persons who take beams GRAPE to become brown? The GRAPE do they favor or harm the health of the skin?The beams GRAPE, they were considered to be less aggressive than the beams UVB, but it has a sufficient risk to be a carcinogen, his effects are accumulative in addition to his effect of cutaneous aging. The less the better... We have sunbathed the whole life and in the last years they repeat to us repeatedly that it is necessary to have precaution: why now is the sun so bad?The solar radiation is less leaked by the ozone layer and penetrate with more intensity. The function of this layer placed to 25 Km high is that of leaking the solar light and it is getting lost. What are the dangers of sunbathing in excess? (aging, cancer...)How can we distinguish a tumor of a normal spot?A spot melánica or spot can be a cancer injury if it is asymmetric, of irregular rims, of diverse colors (black - red), and if they are bigger than 6 mm. Under these circumstances it is necessary to think of coming to a Dermatologist as soon as possible. Four factors that they induce to think about a bad spot?Is the leather cancer treated if it is taken on time? What is the treatment?In leather cancer it is one of the most frequent illnesses on a global scale, occupying approximately 10 % of all the cancers. The World organization of the Health, has thought that in Europe approximately approximately 250.000 new cases will happen every year. What persons have major risk of enduring a leather cancer? |
