Overstimulation
Stimulation is the encouragement of development or the cause of activity in general. For example, "The press provides stimulation of political discourse." An interesting or fun activity can be described as "stimulating", regardless of its physical effects on senses. ''Stimulate'' means to act as a stimulus to; ''stimulus'' means something that rouses the recipient to activity; ''stimuli'' is the plural of ''stimulus''. A particular use of the term is physiological stimulation, which refers to sensory excitation, the action of various agents or forms of energy (stimuli) on receptors that generate impulses that travel through nerves to the brain (afferents). There are sensory receptors on or near the surface of the body, such as photoreceptors in the retina of the eye, hair cells in the cochlea of the ear, touch receptors in the skin and chemical receptors in the mouth and nasal cavity. There are also sensory receptors in the muscles, joints, digestive tract, and membranes around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sensory Overload
Sensory overload occurs when one or more of the body's senses experiences over-stimulation from the environment. There are many environmental elements that affect an individual. Examples of these elements are urbanization, crowding, noise, mass media, and technology. Signs and symptoms There are a wide variety of symptoms that have been found to be associated with sensory overload. These symptoms can occur in both children and adults. Some of these symptoms are: * Irritability * "Shutting down," or refusing to participate in activities and interact with others * Over-sensitivity to touch, movement, sights, or sounds ** Avoiding touching or being touched ** Irritation caused by shoes, socks, tags, or different textures ** Complaining about noises that do not affect others ** Covering eyes around bright lights ** Covering ears to close out sounds or voices * Excitability * Making poor eye contact * Constantly changing activities without completing any tasks * Having trouble wi ...

Social Media
Social media are interactive technologies that facilitate the Content creation, creation, information exchange, sharing and news aggregator, aggregation of Content (media), content (such as ideas, interests, and other forms of expression) amongst virtual communities and Network virtualization, networks. Common features include: * Online platforms enable users to create and share content and participate in social networking. * User-generated content—such as text posts or comments, digital photos or videos, and data generated through online interactions. * Service-specific profiles that are designed and maintained by the List of social networking services, social media organization. * Social media helps the development of online social networks by connecting a User profile, user's profile with those of other individuals or groups. The term ''social'' in regard to media suggests platforms enable communal activity. Social media enhances and extends human networks. Users access so ...

Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The following process connects a person's concepts and expectations (or knowledge) with restorative and selective mechanisms, ...

Stress Management
Stress management consists of a wide spectrum of techniques and psychotherapy, psychotherapies aimed at controlling a person's level of psychological stress, especially chronic stress, generally for the purpose of improving the function of everyday life. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, Psychological stress and sleep, sleep problems, and Depression (mood), depression. The process of stress management is a key factor that can lead to a happy and successful life in modern society. Stress management provides numerous ways to manage anxiety and maintain overall well-being. There are several models of stress management, each with distinctive explanations of mechanisms for controlling stress. More research is necessary to provide a better understanding of which mechanisms actually operate and are effective in practice ...

Psychomotor Agitation
Psychomotor agitation is a symptom in various disorders and health conditions. It is characterized by unintentional and purposeless motions and restlessness, often but not always accompanied by emotional distress and is always an indicative for admission. Typical manifestations include pacing around, wringing of the hands, uncontrolled tongue movement, pulling off clothing and putting it back on, and other similar actions. In more severe cases, the motions may become harmful to the individual, and may involve things such as ripping, tearing, or chewing at the skin around one's fingernails, lips, or other body parts to the point of bleeding. Psychomotor agitation is typically found in various mental disorders, especially in psychotic and mood disorders. It can be a result of drug intoxication or withdrawal. It can also be caused by severe hyponatremia. People with existing psychiatric disorders and men under the age of 40 are at a higher risk of developing psychomotor agitation. ...

Adrenal Fatigue
Adrenal fatigue is a pseudoscientific term used by alternative medicine providers to suggest that the adrenal glands are exhausted and unable to produce adequate quantities of hormones, primarily cortisol, due to chronic stress or infections. There is no scientific basis for the existence of adrenal fatigue, and the term should not be confused with a number of actual forms of adrenal dysfunction such as adrenal insufficiency or Addison's disease. Definition Neither the condition nor the symptoms have any stable or recognized definition. History The term "adrenal fatigue" was invented in 1998 by chiropractor James Wilson and applied to a collection of mostly non-specific symptoms. Lack of evidence A systematic review found no evidence for the condition, supporting the consensus among mainstream endocrinologists that it is a myth. There is no evidence supporting the concept of adrenal fatigue, and it is not a valid diagnosis recognized by the scientific or medical communities. ...

Burnout (psychology)
The ICD-11 of the World Health Organization (WHO) describes occupational burnout as a work-related phenomenon resulting from chronic workplace stress that has not been successfully managed. According to the WHO, symptoms include "feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy." It is classified as an occupational phenomenon but is not recognized by the WHO as a medical or psychiatric condition. Social psychologist Christina Maslach and colleagues made clear that burnout does not constitute "a single, one-dimensional phenomenon." However, national health bodies in some European countries do recognise it as such, and it is also independently recognised by some health practitioners. Nevertheless, a body of evidence suggests that what is termed burnout is a depressive condition. History Kaschka, Korczak, and Broich (2011) advanced the view that bu ...

Anxiety
Anxiety is an emotion characterised by an unpleasant state of inner wikt:turmoil, turmoil and includes feelings of dread over Anticipation, anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, Somatic anxiety, somatic complaints, and Rumination (psychology), rumination. Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. It is often accompanied by muscular tension, restlessness, Fatigue (medical), fatigue, inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration. Anxiety is closely related to fear, which is a response to a real or perceived immediate threat (fight-or-flight response); anxiety involves the expectation of a future t ...

Stress (biology)
Stress, whether physiological, biological or psychological, is an organism's response to a stressor, such as an environmental condition or change in life circumstances. When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. In humans and most mammals, the autonomic nervous system and Hypothalamic–pituitary–adrenal axis, hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress. Two well-known hormones that humans produce during stressful situations are adrenaline and cortisol. The Sympathoadrenal system, sympathoadrenal medullary axis (SAM) may activate the fight-or-flight response through the sympathetic nervous system, which dedicates energy to more relevant bodily systems to Acute stress reaction, acute adaptation to stress, while the parasympathetic nervous system returns the body to homeostasis. The second major physiological stress-response center, the HPA axis, regulates the release ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drug Withdrawal
A drug is any chemical substance other than a nutrient or an essential dietary ingredient, which, when administered to a living organism, produces a biological effect. Consumption of drugs can be via insufflation (medicine), inhalation, drug injection, injection, smoking, ingestion, absorption (skin), absorption via a dermal patch, patch on the skin, suppository, or sublingual administration, dissolution under the tongue. In pharmacology, a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. A pharmaceutical drug, also called a medication or medicine, is a chemical substance used to pharmacotherapy, treat, cure, preventive healthcare, prevent, or medical diagnosis, diagnose a disease or to promote well-being. Traditionally drugs were obtained through extraction from medicinal plants, but more recently also by organic synthesis. Pharmaceutical drugs may be used for a limited duration, or on a re ...

Recommender System
A recommender system (RecSys), or a recommendation system (sometimes replacing ''system'' with terms such as ''platform'', ''engine'', or ''algorithm'') and sometimes only called "the algorithm" or "algorithm", is a subclass of information filtering system that provides suggestions for items that are most pertinent to a particular user. Recommender systems are particularly useful when an individual needs to choose an item from a potentially overwhelming number of items that a service may offer. Modern recommendation systems such as those used on large social media sites make extensive use of AI, machine learning and related techniques to learn the behavior and preferences of each user and categorize content to tailor their feed individually. Typically, the suggestions refer to various decision-making processes, such as what product to purchase, what music to listen to, or what online news to read. Recommender systems are used in a variety of areas, with commonly recognised ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
