UVA rays from sunlight and tanning - pros and cons

Sunlight contains UV rays that are invisible to the human eye and are classified according to their wavelength, which is measured in nanometers (nm). It is worth highlighting that the shorter the wavelength, the stronger the energy from sunlight. They are divided into three types:

  • UVC, whose wavelength varies between 200 and 280 nm. These rays are absorbed by the ozone layer before reaching the earth crust and are potentially dangerous to humans
  • UVB or medium wave rays (from 280 to 320 nm) are also largely absorbed by the ozone, yet reach the earth's surface
  • UVA comprising less harmful solar radiation. This wave length is between 320 and 400 nm and most of these rays reach the earth's surface.

UVA rays, while not as dangerous as UVB, penetrate our skin causing serious disadvantages if their use is excessive or if you are exposed to them before you are 30.

Sunbathing gives us many benefits for our health, and this can also be achieved with some sunbeds but both natural and artificial tanning carry disadvantages if we do not take precautions or use it in excess.

The action of sunlight can be direct or indirect, the latter is produced by the reflection of the rays on the Earth's surface and their spread through the clouds. For this reason, a cloudy day does not prevent solar rays to get you a sunburn. Similarly, depending on the area where we are also you receive a percentage of the sunlight reflected on the earth. For example, snow reflects about 85% of the sun, and beach sand about 15%. Which means we must also take care during the winter if we expose ourselves to the sun.

Sunbeds use UVA rays, since they are less intense and harmful, yet it has been shown that this practice also causes damage to the skin.


Sunbathing can be transformed into a kind of healing therapy. In addition to the aesthetic benefits, the sun can gradually bring us many other benefits. Sunbathing treatments  can reinforce the body for certain diseases and help prevent many others.

The body needs to form strong bones and teeth, and calcium, but this is not easily absorbed by our metabolism. To facilitate the absorption of calcium in our body, we need vitamin D. Some foods are naturally rich in vitamin D, but we must consume adequate amounts daily for it to be absorbed. Our body is able to synthesize this vitamin more quickly thanks to the action of the sun. Adequate exposure can act as a additional “medicine” to some treatments.

Today sunbeds have become an increasingly common method when it comes to getting tanned. You can get a nice color in just a few minutes without having to go to the beach at any time of year, but be careful in its use, in particular the total duration of the exposure per session, and check if it is suitable for your skin type.
