The body perspires (sweats) when the body works or overworks. In this sense is not a 9 to 5 job that one goes to. Work in this sense is the body in motion either internally or externally. The body at work generates heat and this heat produces sweat. This sweat/perspiration is secreted through the skin and it main purpose is to cool the body. Some forms of work that cause the body to heat or overheat and thus cause the body to perspire are physical labor, sports and exercise, sickness such fever (caused by internal work, the immune system combating the illness), and sweating can also be caused by overdressing. Perspiration is an odorless substance that is mostly water with urea and dissolved salts. Offensive body odors are produced when the perspiration comes in contact the with bacteria found on the skin.
Deodorants are classified as cosmetics and fall under the watchful eye of the Federal Food & Drug Administration (FDA). Deodorant with antiperspirants contain aluminum and the FDA has several warning regarding aluminum. First, the FDA has classified aluminum as a neurotoxin. Large amounts aluminum can be destructive to the blood brain barrier. The FDA has acknowledged that aluminum in antiperspirants can be absorbed through the skin and warns that those suffering from renal dysfunction maybe a higher risk when using antiperspirants daily. Plus the Alzheimer Society has noted the connection to there being a higher level of aluminum in the brain of those with Alzheimer.
There has been a large Internet scare that the use of antiperspirants have been linked to the development of breast cancer. The American Cancer Society and the National Cancer Institute has stated the studies have not shown any link or they are not aware of any link between antiperspirants and the development of breast cancer. However a study in the European Journal of Cancer Prevention has found a connection to breast cancer and the use of antiperspirants. A further study reviewing the early finding came to the conclusion that though a connection may have been found in test animals, but the does not exist any reliable evidence that is the case for humans.
With the above warning, acknowledgements, possibilities, and plus the simple fact that some people are allergic to the aluminum in antiperspirants people may want to look for alternatives for the daily use of antiperspirants. There does exist alternatives to the use of antiperspirants such as the use of deodorants that do not contain antiperspirants, more frequent washing of the skin, plus the use of lotions, oils, powders.
