UVA Radiation And Sun Tanning Lotions

By Haywood Hunter


Sun tanning lotions and electromagnetic radiations are synonymous with each other when developing products of this kind. Studies of electromagnetic radiations are carried out by scientists in their various fields of study when formulating the perfect product to suit each individuals skin type. Some people are just prone to burning when spending lengthy periods in the sun.

This is probably a genetic susceptibility they have towards the harmful rays of the sun and it is because of factors such as these that scientists use devices such as spectrophotometers and others. The spectrophotmeter was developed by G.M.B.Dobson. Early studies of the ozone layer came about in the early nineteen hundreds because of work done by physicists named Charles Fabry and Henri Buisson. Their work entailed studies of the ozone layer since the ozone layer was discovered in nineteen thirteen and has played a vital role when producing sun tanning lotions.

The ozone layer forms a protective band around the earth as this gas, namely ozone, provides consistent protection. However, in the passed few years, carbon emissions from motor vehicles and other machinery have impacted this protective band around the earth. This is one of the reasons why scientists formulating sun tanning lotions require and acquire knowledge of this sort.

This is all dependent on the size of their waves as recorded on a sine graph. They are measured in nanometres and can vary from approximately one hundred nanometres through to over two hundred nanometres. For scientists and biologists that formulate sun tanning lotions these are important criteria to take into consideration.

Each are labelled with their own unique qualities and these are factor dependent. To the layperson, the higher the factor sun tanning lotions they choose to use the better protected they will be. In general this is why many people opt to buy the highest factor sun tanning lotions possible.

People using sun tanning lotions are aware of these detrimental effects that electromagnetic radiations have. The earth has its own sun tanning lotions so to speak and these are protective spheres that are surround the earth as you go upwards from the ground towards the upper reaches of the atmosphere before entering space. Some of these spheres to mention a few are called the atmosphere, hydrosphere and lithosphere.

Ultraviolet radiations are in fact electromagnetic radiations emitted by the sun that the human eye cannot determine. They are packages of electromagnetic energy on a microscopic level that penetrate the upper reaches of the atmosphere of the earth. Should ozone in the ozone layer of the earth become depleted, this could have and is having dire consequences on organic level that so to speak does not have its own sun tanning lotions product.

Skin has its own sun tanning lotions product. It safeguards itself in the same way as a leaf on a tree is protected by its outer membranes of organic material just as the inside of a tree is protected by its bark. It is advisable to give it extra protection when in the sun.
