Atmosphere And Elements 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.

The ozone layer and sun tanning lotions is a concern that many worry about when spending time at the beach. Studies show that the ozone in actuality is a gas and forms part of the lower portion of the stratosphere. This portion of the stratosphere is located approximately between twenty and thirty kilometers above the surface of the earth. Ozone is a chemical and it is an effective chemical to say the least in acting as a protector against the harsh ultraviolet rays of the sun just as Sun tanning lotions will do too.

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.

One does not realize it when your skin starts to burn and usually the after effects are only realized a lot later. In order to prevent dry skin and lined skin later on in life parents are starting to realize that by using sun tanning lotions whilst in the sun is imperative. Today many different types of sun tanning lotions can be bought.

This is why when you buy a sun tanning lotions of this kind, they are labeled according to their protective factor. The ozone layer was discovered in the early nineteen hundreds by French physicists namely Charles Fabry and Henri Buisson. Eventually with the help of a British meteorologist G. M. B Dobson, a device was devised called the spectrophotometer or the Dobson meter.

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.

The reasons for studying subjects that involve sun tanning lotions is important as understanding them provides producers of Sun tanning lotions with valuable information as to how to combat the effects of harmful radiations. It is advisable however according to many not to sit or bathe in the sun for long periods of time. By minimizing the amount of time you spend in the sun you are able to counteract the harmful side effects that radiations such as these cause.
