Condom fatigue is a term used by medical professionals and safer sex educators to refer to the phenomenon of decreased condom use. Condom fatigue can also be used to describe a general weariness of and decreased effectiveness of safer sex messages. This is sometimes called prevention fatigue. The term has particularly been used to describe men who have sex with men , though the term applies to people of all gender s and sexual orientation s. Condom fatigue has been partially blamed for an increase in HIV infection rates, though this has not been substantiated in any study.

There is near universal support that the fatigue experienced by people with MS goes beyond that of people without the disease. Many Multiple Sclerosis patients report sleeping more than 12 hours a night on successive nights and still being too tired to complete their daily duties despite feeling physically rested. This fatigue is also highly variable and there are some with MS who do not experience neurological fatigue as a primary symptom. As this fatigue is an invisible symptom, and because of the difficulty of explaining the tired brain feeling of neurological fatigue, others can misinterpret the behavior of persons with MS as lack of effort, but it is important for those dealing with MS patients to realize that this may not be the case. ref cite journal author Mills RJ, Young CA, Pallant JF, Tennant A title Development of a patient reported outcome scale for fatigue in multiple sclerosis The Neurological Fatigue Index NFI MS journal Health Qual Life Outcomes volume 8 issue pages 22 year 2010 pmid 20152031 pmc 2834659 doi 10.1186 1477 7525 8 22 url ref The specific causes of fatigue in Multiple Sclerosis sufferers are not fully understood.

Listener fatigue can occur when listening for extended periods of time to certain material. The exact cause has been the subject of debate, but it is generally accepted that it can be caused by the introduction of artifacts in the program material. This is an extension of the Equal loudness contour quantifiable psychological perception of sound , adding time variance effects. If listeners get fatigued when listening to a radio station they may tune out, and either consciously or unconsciously they may come to avoid listening to that station. Data reduction systems are another possible reason why listener fatigue can creep in. The constant quest for loudness war greater loudness , an obsession with pushing levels to the maximum, and a lack of understanding of the ways in which digital equipment can generate distortion all seem to lead to an increase in listener fatigue.

voting Unreferenced date June 2008 In politics , voter fatigue is the voter apathy apathy that the electorate can experience when they are required to vote too often. It is often used as a criticism of the direct democracy system, in which voters are constantly asked to decide on policy via Referendum referenda . However, proponents often counter that voter fatigue may be lessened by direct democracy as voters will feel their vote has more effect. Voter fatigue can cause notoriously low voter turnout rates, and potentially more protest vote , and supposedly occurs for a variety of reasons voters are not interested in the issue. voters are bothered by the inconvenience of physically voting. voters feel their vote will not count the election has already been won by one side. voters feel that it is not worth their while to educate themselves as to the issues and hence their vote would not be worth making. This is related to the concept of rational ignorance . voters have to vote for too many institutions too often . Amongst the methods that can be used to combat voter fatigue are Making it mandatory to vote, as e.g. in Australian electoral system Australia , Elections in Belgium Belgium or Elections in Brazil Brazil . Using sortition to choose those eligible to vote thus increasing the worth of a single vote . E democracy , proxy voting and delegated voting .

Olfactory fatigue , also known as odor fatigue or olfactory adaptation , is the temporary, normal inability to distinguish a particular odor after a prolonged exposure to that airborne compound. ref Odors chapter, Fundamentals volume of the ASHRAE Handbook , ASHRAE, Inc., Atlanta, GA, 2005 ref For example, when entering a restaurant initially the odor of food is often perceived as being very strong, but after time the awareness of the odor normally fades to the point where the smell is not perceptible or is much weaker. After leaving the area of high odor, the sensitivity is restored with time. Perfume counters will often have containers of coffee beans which tend to reset olfaction . Anosmia is the permanent loss of the sense of smell, and is different from olfactory fatigue. It is a term commonly used in wine tasting , where one loses the ability to smell and distinguish wine bouquet after sniffing at wine s continuously for an extended period of time. The term is also used in the study of indoor air quality , for example, in the perception of odors from people, tobacco , and cleaning agents. Olfactory fatigue is an example of neural adaptation or sensory adaptation . Our bodies become desensitised to stimuli in order to prevent the overloading of our nervous system, thus allowing it to respond to new stimuli that are out of the ordinary . Our sense of smell is considered to be one of the least developed senses we possess.

The increasing prominence of information technology and the Internet in employment, finance, recreation and other aspects of people s lives, and the ensuing introduction of secure transaction technology, has led to people accumulating a proliferation of accounts and passwords.
