The Internet plays an increasingly important role in people’s lives。Now，People can use the Internet on various electronic devices at any time，This makes it easier for people to obtain bet365 horse racing odds from the Internet。A survey of more than 12,000 people in 12 countries around the world，9 countries (Russia、China、India、Mexico、Brazil、United States、Italy、Australia and Germany)，More than 75% of participants use the Internet to search for health-related information，Among them，60% of Chinese Internet users use the Internet to search for health、Medical、Disease related information，56% of people will use bet365 horse racing odds on the Internet for self-diagnosis。This shows，The Internet has become the most popular way to obtain bet365 horse racing odds。

Undeniable，This way of obtaining bet365 horse racing odds is generally positive。For example，Search through the Internet，People can avoid long hospital queues、High cost and other issues，And you can quickly and effectively obtain information about the symptoms you want to know；On some health online forums，People can discuss and communicate with others who have gone through the same experience，Seeking comfort；Due to the anonymity of the Internet，People can search for more private diseases without fear of discrimination。However，Current research shows，For those who are anxious about their health，Searching for bet365 horse racing odds online may exacerbate concerns about their symptoms，In severe cases, it may even cause pain、A series of physical and mental problems such as anxiety，Thus affecting normal work and life。Some researchers pointed out，People who are more anxious about their health search for bet365 horse racing odds on the Internet more frequently，The uncertainty of online information in turn aggravates their anxiety symptoms，For further self-diagnosis or seeking comfort，They will search again，This will form a vicious cycle of "search-anxiety-search"。Excessive or repetitive health-related searches on the Internet caused by excessive anxiety about one’s own health，Abnormal patterns of behavior that result in increased anxiety or fear is called Cyberchondria。

　　bet365 horse racing odds is similar to illness anxiety disorder

　2001，Valley originally began researching cyberchondria as a disorder，He believes that cyberchondriasis is a condition caused by excessive fear of disease caused by searching a large amount of health-related information on the Internet，And there is already a global trend。In recent years，With the development of research on cyberchondriasis，Different scholars have different definitions of it。Recupero defines it as health concerns resulting from increased online searches for bet365 horse racing odds。Proposed by Starcevic，Cyberchondria mainly refers to excessive or repetitive online searches for health-related information，The motivation is to relieve health-related pain or anxiety，But the result is increased anxiety。McElroy and others believe，Cyberchondriasis has a multidimensional structure，Including coercion、Pain、Excessive、Five dimensions of comfort and distrust in medical professionals。

As an emerging disorder, cyberchondriasis does not yet have specific diagnostic criteria in DSM-V。Illness Anxiety Disorder is a disorder similar in concept and nature to cyberchondria，The diagnostic criteria in DSM-V are: (1) Suspecting that you have a serious disease；(2) Physical symptoms are absent or present but of low intensity，And have another disease or are at high risk (e.g. strong family history)，Individual thus exhibits excessive concern for disease；(3) The individual shows high anxiety about bet365 horse racing odds and is easily worried about bet365 horse racing odds status；(4) The individual exhibits excessive bet365 horse racing odds-related behaviors；(5) Symptoms present for at least 6 months，The diseases that individuals worry about will change over time；(6) Other mental disorders cannot explain this symptom。Therefore，The diagnostic criteria for disease anxiety disorder can provide a reference for the diagnosis of cyberchondriasis。Also，Cyberchondriasis and bet365 horse racing odds Anxiety、There is a high correlation between symptoms such as problematic Internet use。Therefore，Research on similar or related diseases of cyberchondriasis，For a deeper understanding of the conceptual connotation of cyberchondriasis、Basic features、Diagnostic criteria、Influencing factors are of great significance。

Currently，Most studies show that，Online Health Research can lead to negative emotional reactions，such as fear and excitement，And excessive search for bet365 horse racing odds will aggravate the individual’s own anxiety，It may even eventually develop into some mental disorders，such as anxiety disorder、Mood disorders, etc.。Internet hypochondriasis, which is mainly characterized by online health searches, is also extremely harmful to individuals and society。First，The results obtained by searching for bet365 horse racing odds online are extremely inaccurate。Secondly，Excessive search for bet365 horse racing odds can increase your own anxiety and may even lead to serious mental illness。Cyberchondriasis has been linked to health anxiety、There is a high correlation between intolerance of uncertainty and symptoms such as obsessive-compulsive disorder，And there is a research finding，After repeatedly searching for health-related information on the Internet，4%-6% of patients show pathological grade disease concerns，Severe enough to meet DSM-IV diagnostic criteria。In addition，Excessive search for health-related information may also lead to excessive use of medical resources。

　　Affected by individual bet365 horse racing odds and network environment bet365 horse racing odds

About the pathogenesis of cyberchondriasis，Starcevic et al. proposed a related model，This model posits that cyberchondria is essentially a behavior seeking a sense of security through constant online searches for bet365 horse racing odds，It is designed to address increasing anxiety or distress after searching for bet365 horse racing odds and concerns that persist after an initial online health search。These anxieties、Pain or worry is often caused by wrong beliefs，If the search results rank higher (such as brain tumors)，The better it can explain a specific symptom (such as headache)。Individual fails to obtain reassuring information online，As a result, I am more worried and anxious about my health，will search for information again as compensation，Eventually leads to a vicious cycle。Discovered through combing domestic and foreign literature，There is currently little research on the pathogenesis of cyberchondriasis，And most studies have not yet delved into its internal neurophysiological mechanisms。Illness anxiety disorder is a disorder that is conceptually and qualitatively similar to cyberchondria，Characterized by having no or only mild symptoms，Still have excessive fear of having serious illness，Anxiety and excessive health-related behaviors during the process。Research by Grossi et al.，Interoception is more sensitive in patients with illness anxiety disorder。Barsky et al. proposed the “Somatosensory Amplification Model”，And points out that hypochondriacs tend to focus on their physical sensations，and experience it as nervousness and uneasiness。Research has shown，The hippocampus is responsible for receiving sensory and interoceptive information。Functional magnetic resonance imaging studies also show，Higher interoceptive sensitivity in patients with illness anxiety disorder may be related to hippocampal hyperconnectivity。Also，Significantly reduced functional connectivity between the left extrastriate area and paracentral lobule of the brain may contribute to the misjudgment of body representation in patients with illness anxiety disorder，Extrastriatal area、Hyperconnectivity such as the amygdala may also contribute to patients’ higher anxiety levels。In summary，Due to the similarity between cyberchondriasis and illness anxiety disorder，Research on the intrinsic neurophysiological mechanisms of disease anxiety disorder can provide some reference for a deeper understanding of the pathogenesis of cyberchondriasis。

Through literature review，It can be found that the factors that affect bet365 horse racing odds mainly include individual factors and network environmental factors。

Some personality traits of an individual play a key role in the onset of cyberchondriasis。First，Individuals with health anxiety symptoms are more likely to experience negative emotions when searching for bet365 horse racing odds online。There are also studies showing that，Using the Internet for the purpose of searching for bet365 horse racing odds will also increase individuals’ health anxiety，And it is also associated with an increase in depressive symptoms。Secondly，Inability to tolerate uncertainty is one of the risk factors for cyberchondriasis。People often think that they can get more information by searching online，Thereby reducing our uncertainty about the problem，However, due to the ambiguity of network information，Sometimes after searching online，Individual uncertainty may increase，Especially when network information conflicts with each other，People may go overboard to reduce uncertainty、Repeated search。Again，There is a moderate correlation between obsessive-compulsive symptoms and cyberchondriasis。Some researchers proposed，Some features of cyberchondria appear to be obsessive，Research by Starcevic et al.，This compulsion may be due to the fear of not being able to find needed or important bet365 horse racing odds once you stop searching，And the attendant uncertainty about health status。Individuals despite negative effects such as pain and increased health anxiety，But individuals’ search for bet365 horse racing odds or comfort through the Internet will not stop，On the contrary, it may increase。It’s worth noting，In addition to the above factors，Perfectionism Trait、Internet addiction and other individual factors will play a certain role in the occurrence of cyberchondriasis，Visible，Cyberchondriasis is the interaction between multiple factors、The result of joint action。

Except for individual factors，The impact of network environmental factors on cyberchondriasis cannot be underestimated。Although the Internet has penetrated into every aspect of people’s lives，But there are still some problems that cannot be ignored，These issues impact the user experience when people search for bet365 horse racing odds online，Thus affecting their emotions、Cognition、Behavior etc.，Ultimately leading to the emergence of cyberchondriasis。For example，Many web pages will sort them by website click-through rate，The top ones are often the websites with the highest click-through rate，When people search for bet365 horse racing odds online，Often tend to pay attention to those that are rare、Severe illness，Thus causing its click rate to be higher than those of more common and common diseases，So more serious illnesses will be ranked higher，This means other users will notice them more easily，The click rate will also increase further，This may further increase people’s anxiety。

At present, cyberchondriasis has not received widespread attention from domestic and foreign scholars，There are still large gaps in related research topics。First，There are currently no studies that have conducted an in-depth exploration of the internal neurophysiological mechanisms underlying the onset of cyberchondriasis，This greatly limits the intervention and treatment of cyberchondriasis and related diseases，Future research should further explore this aspect，Enrich the theoretical basis of this field。At the same time，Research has shown，Cyberchondriasis and other conditions such as depression、Forced、Anxiety, etc. are highly correlated，But the relationship between cause and effect or interaction is not clear，Strengthening research in this area in the future will help prevent and treat cyberchondriasis and related diseases，It is of great significance to improve the happiness of people’s lives。In addition，Research on cyberchondriasis helps to improve people’s health awareness，Remind people to standardize medical treatment，Don’t blindly trust online bet365 horse racing odds，Has positive social significance。Research on the field of cyberchondriasis can also promote the professional and standardized development of online medical information，And then become a driving force to promote the progress of the national medical system and social welfare system。
