It doesn’t matter whether you get it from the sun or from artificial sources such as sun lamps and tanning beds.
UV radiation is one part of the spectrum of light that reaches the earth from the sun. At the UV end of the spectrum, the wavelengths are too short to be visible to the naked eye. They range in length from 100 to 400 nanometers (nm, or billionths of a meter) and are classified — from the longest to the shortest — as UVA (320 to 400 nm), UVB (290 to 315 nm), and UVC (100 to 280 nm). UVA rays, which penetrate deep into the skin, are responsible for tanning. Tanning beds use fluorescent bulbs that emit mostly UVA, with smaller doses of UVB. The UVA radiation is up to three times more intense than the UVA in natural sunlight, and even the UVB intensity may approach that of bright sunlight. Meanwhile, claims for the healthfulness of indoor tanning. One claim is that it helps build a base that protects against sunburn. It does, but only slightly — the equivalent of a sunscreen rated SPF 4 or less. Another claim is that tanning is a good way to stimulate the skin’s production of vitamin D, a hormone that’s essential to bone health and has been linked to a reduced risk for several cancers.
New and up to date information tells us that reasonable amounts of sun is good for you-to the point that it can protect from some cancers. Basically, a little bit of sun each day is good for you. Found to be helpful with bone health, to muscle mass, reduction in asthma and even help with joy etc. Have heard of one case, where a patient was given tanning bed treatment-so that the patient could get off medication. And to get some real time exposure and info: Check out “Bronzage Marie-Tan, Located at 591 rue Principale, Lachute Qc., Ca. Just talk to Pierre-very helpful.
