do not need to experience being in the sun exposure to UV rays even on cloudy days or through the reflection of sun on the beach under an umbrella, or fluorescent light may be produced.
UV rays are divided, according to its wavelength: UV
• A - 320 to 400 um. Between 30 and 50% of these rays reach deeper levels of the dermis and produce radiation that tans the skin, with some side effects.
• UV B - 290 to 320 um. They have a lot of energy, they penetrate the epidermal level and cause tanning with enough side effects, can alter the cellular DNA and cause cancer, melanogenic action as they develop and inflamed skin.
• UV C - less than 290 um. Rays are the most energy. Are very hazardous to humans and most do not reach the Earth's surface because the ozone layer absorbs from the atmosphere.
was once thought that only type B radiation was harmful, but is now known that the combined effect of UV-A and B affects the skin, UVA rays reach the earth's surface 1,000 times more than UVB and penetrate deep into the skin, altering the tissue and induces collagen photosensitivity reactions and dehydration that dries the skin and elasticity remain and cause injuries characterizing the photo aging and skin cancer.
Not all patients with lupus are sensitive to the sun. Only 30% are affected by it, and there are also a large variety of degrees: Some people may be in the sun for 20 minutes without problems, but they develop fatigue, fever and rash if they are for 45 minutes. This can vary from one person to another. even from one race to another. Recommendations
1. Hours
We must be careful between at 10 am and 4 pm, times where UV rays affect angles and do much damage to the skin, after the 4 pm, UV rays are oblique and start being more easily absorbed by the atmosphere.
2.
La Ropa We choose what cover our skin, taking into account the thickness. The solar protection capacity is expressed as a UV Protection Factor (UPF)
exists in the market UPF clothing as is the case of " Coolibar ( http://www.coolibar.com/ ) and products that raise the level of sun protection clothing, as in the case of " Sun Guard." ( https: / / sunguardsunprotection.com /)
3. Hats
The facial skin is very sensitive to photo-aging, especially the cheeks, nose and chin, a classic baseball cap is not sufficient, wear wide-brimmed hats that protect much of the face.
For example:
4. Eyewear
should use sunglasses to protect U. VA and VB U. absorb these rays to prevent damage, excess solar radiation is responsible for the irritation of our eyes can cause conjunctivitis and inflammation of the cornea ( keratitis).
5. Places open
Beware at beaches, pools, sand, snow and their surfaces act as amplifiers of the sun's rays. (In water up to 80% and 50% sand)
in high places take into account that the distance from the sun to the earth is lower, so the risk increases.
6. Solariums -
Sun Beds Sunbeds emit radiation UV to achieve their objective in a short time, is generally not recommended for use because it can cause skin cancer and even less if you suffer from Lupus or any condition sensitive.
7. transport vehicle
Within the same risk you run out of it, unless you count the moons that absorb UV transmission, these between darker and metallic provide greater protection.
8. sun-protective cream
Sunscreen is used to increase skin tolerance to sunlight, they should be applied half an hour before sun exposure to achieve good absorption, and reapply every couple of hours as the protection factor and having the day is cloudy.
on the market are various brands of sunscreens with various sun protection factors (SPF), the factor indicates how long you can stay in the sun without your skin becomes red, this is how an SPF 15 sunscreen allows you to be in the sun 15 times without use, with SPF 30 will be 30 times more and so on.
A final recommendation is to seek assurance products.
