Euphoria (/juːˈfɔːriə/ ⓘ yoo-FOR-ee-ə) is the experience (or affect) of pleasure or excitement and intense feelings of well-being and happiness.[1][2] Certain natural rewards and social activities, such as aerobic exercise, laughter, listening to or making music and dancing, can induce a state of euphoria.[3][4] Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, such as mania.[5] Romantic love and components of the human sexual response cycle are also associated with the induction of euphoria.[6][7][8] Certain drugs, many of which are addictive, can cause euphoria, which at least partially motivates their recreational use.[9]

Hedonic hotspots – i.e., the pleasure centers of the brain – are functionally linked. Activation of one hotspot results in the recruitment of the others. Inhibition of one hotspot results in the blunting of the effects of activating another hotspot.[10][11] Therefore, the simultaneous activation of every hedonic hotspot within the reward system is believed to be necessary for generating the sensation of an intense euphoria.[12]

History

[edit]

The word "euphoria" is derived from the Ancient Greek terms εὐφορία: εὖ eu meaning "well" and φέρω pherō meaning "to bear".[13][14] It is semantically opposite to dysphoria.

A 1706 English dictionary defines euphoria as "the well bearing of the Operation of a Medicine, i.e., when the patient finds himself eas'd or reliev'd by it".[15]

During the 1860s, the English physician Thomas Laycock described euphoria as the feeling of bodily well-being and hopefulness; he noted its misplaced presentation in the final stage of some terminal illnesses and attributed such euphoria to neurological dysfunction.[16] Sigmund Freud's 1884 monograph Über Coca described (his own) consumption of cocaine producing "the normal euphoria of a healthy person",[17] while about 1890 the German neuropsychiatrist Carl Wernicke lectured about the "abnormal euphoria" in patients with mania.[18]

A 1903 article in The Boston Daily Globe refers to euphoria as "pleasant excitement" and "the sense of ease and well-being".[19] In 1920 Popular Science magazine described euphoria as "a high sounding name" meaning "feeling fit": normally making life worth living, motivating drug use, and ill formed in certain mental illnesses.[20] Robert S. Woodworth's 1921 textbook Psychology: A study of mental life, describes euphoria as an organic state which is the opposite of fatigue, and "means about the same as feeling good."[21]

In 1940, The Journal of Psychology defined euphoria as a "state of general well being ... and pleasantly toned feeling."[22] A decade later, finding ordinary feelings of well being difficult to evaluate, American addiction researcher Harris Isbell redefined euphoria as behavioral changes and objective signs typical of morphine.[23] However, in 1957 British pharmacologist D. A. Cahal did not regard opioid euphoria as medically undesirable but an effect which "enhance[s] the value of a major analgesic."[24] The 1977 edition of A Concise Encyclopaedia of Psychiatry called euphoria "a mood of contentment and well-being," with pathologic associations when used in a psychiatric context. As a sign of cerebral disease, it was described as bland and out of context, representing an inability to experience negative emotion.[25]

In the 21st century, euphoria is generally defined as a state of great happiness, well-being and excitement, which may be normal, or abnormal and inappropriate when associated with psychoactive drugs, manic states, or brain disease or injury.[26]

Neuropsychology

[edit]
Main article: Reward system § Pleasure centers

Hedonic hotspots are functionally interrelated neural substrates/structures that (intrinsically or extrinsically) generate the feelings of pleasure. Activation of one hedonic hotspot involves the stimulation of the others. Inhibition of one hedonic hotspot blunts the activation the other ones.[10][11] Therefore, the simultaneous activation of every hedonic hotspot within the reward system is probably necessary for generating the sensation of euphoria.[12]

Types

[edit]

Many different types of stimuli can induce euphoria, including psychoactive drugs, natural rewards, and social activities.[1][27][4][5] Affective disorders such as unipolar mania or bipolar disorder can involve euphoria as a symptom.[5]

Exercise-induced

[edit]
This section is an excerpt from Neurobiological effects of physical exercise § Exercise-induced euphoria.[edit]
Continuous exercise can produce a transient state of euphoria – an emotional state involving the experience of pleasure and feelings of profound contentment, elation, and well-being – which is colloquially known as a "runner's high" in distance running or a "rower's high" in rowing.[28][29][30][31]

Music-induced

[edit]
Further information: Frisson

Euphoria can occur as a result of dancing to music, music-making, and listening to emotionally arousing music.[4][32][33] Neuroimaging studies have demonstrated that the reward system plays a central role in mediating music-induced pleasure.[33][34] Pleasurable emotionally arousing music strongly increases dopamine neurotransmission in the dopaminergic pathways that project to the striatum (i.e., the mesolimbic pathway and nigrostriatal pathway).[32][33][34] Approximately 5% of the population experiences a phenomenon termed "musical anhedonia", in which individuals do not experience pleasure from listening to emotionally arousing music despite having the ability to perceive the intended emotion that is conveyed in passages of music.[34]

A clinical study from January 2019 that assessed the effect of a dopamine precursor (levodopa), dopamine antagonist (risperidone), and a placebo on reward responses to music – including the degree of pleasure experienced during musical chills, as measured by changes in electrodermal activity as well as subjective ratings – found that the manipulation of dopamine neurotransmission bidirectionally regulates pleasure cognition (specifically, the hedonic impact of music) in human subjects.[35][36] This research suggests that increased dopamine neurotransmission acts as a sine qua non condition for pleasurable hedonic reactions to music in humans.[35][36]

Sex-induced

[edit]

The various stages of copulation may also be described as inducing euphoria in some people. Various analysts have described either the entire sexual act, the moments leading to orgasm, or the orgasm itself as the pinnacle of human pleasure or euphoria.[37]

Drug-induced

[edit]
A large dose of methamphetamine causes a drug-induced euphoria.[38]

A euphoriant is a type of psychoactive drug which tends to induce euphoria.[39] Most euphoriants are addictive drugs due to their reinforcing properties and ability to activate the brain's reward system.[5]

Psychedelics

[edit]

Traditional psychedelic drugs, such as LSD and psilocybin are capable of inducing euphoria despite lacking addictive qualities. The Global Drug Survey has revealed that out of 22,000 participant reports, MDMA, LSD, and psilocybin mushrooms were ranked most positively on the Net Pleasure Index of all recreational drugs included in the study.[40]

Stimulants

[edit]

Dopaminergic stimulants like amphetamine, methamphetamine, cocaine, MDMA, and methylphenidate are euphoriants.[1][5] Nicotine is a parasympathetic stimulant that acts as a mild euphoriant in some people.[5] Xanthines such as caffeine and theobromine may also be considered mild euphoriants by some.[medical citation needed]

Chewing areca nut (seeds from the Areca catechu palm) with slaked lime (calcium hydroxide) – a common practice in South- and Southeast Asia – produces stimulant effects and euphoria.[41][42][43] The major psychoactive ingredients – arecoline (a muscarinic receptor partial agonist)[42][44] and arecaidine (a GABA reuptake inhibitor)[45][46] – are responsible for the euphoric effect.[47][48]

Depressants

[edit]

Certain depressants can produce euphoria; some of those drugs in this class include alcohol in moderate doses,[49][50] γ-hydroxybutyric acid (GHB),[1][51] and ketamine.[1]

Some barbiturates and benzodiazepines may cause euphoria. Euphoriant effects are determined by the drug's speed of onset,[52] increasing dose,[53] and with intravenous administration.[54] Barbiturates more likely to cause euphoria include amobarbital, secobarbital and pentobarbital.[55][56] Benzodiazepines more likely to cause euphoria are flunitrazepam, alprazolam and clonazepam.[52][57][58] Benzodiazepines also tend to enhance opioid-induced euphoria.[59]

Pregabalin induces dose-dependent euphoria.[60][61] Occurring in a small percentage of individuals at recommended doses, euphoria is increasingly frequent at supratherapeutic doses (or with intravenous- or nasal administration).[62][61][60] At doses five times the maximum recommended, intense euphoria is reported.[60] Another GABA analogue, gabapentin, may induce euphoria.[63] Characterized as opioid-like but less intense,[clarification needed] it may occur at supratherapeutic doses, or in combination with other drugs, such as opioids or alcohol.[63] Ethosuximide and perampanel can also produce euphoria at therapeutic doses.[64][65]

Opioids

[edit]

μ-Opioid receptor agonists are a set of euphoriants[5] that include drugs such as heroin, morphine, codeine, oxycodone, and fentanyl. By contrast, κ-opioid receptor agonists, like the endogenous neuropeptide dynorphin, are known to cause dysphoria,[5] a mood state opposite to euphoria that involves feelings of profound discontent.

Cannabinoidergics

[edit]

Cannabinoid receptor 1 agonists are a group of euphoriants that includes certain plant-based cannabinoids (e.g., THC from the cannabis plant), endogenous cannabinoids (e.g., anandamide), and synthetic cannabinoids.[5]

Inhalants

[edit]

Certain gases, like nitrous oxide (N2O, aka "laughing gas"), can induce euphoria when inhaled.[5][66]

Glucocorticoids

[edit]

Acute exogenous glucocorticoid administration is known to produce euphoria, but this effect is not observed with long-term exposure.[5]

Fasting–induced

[edit]

Fasting has been associated with improved mood, well-being, and sometimes euphoria. Various mechanisms have been proposed and possible applications in treating depression considered.[67]

Neuropsychiatric

[edit]

Mania

[edit]

Euphoria is also strongly associated with both hypomania and mania, mental states characterized by a pathological heightening of mood, which may be either euphoric or irritable, in addition to other symptoms, such as pressured speech, flight of ideas, and grandiosity.[68][69]

Although hypomania and mania are syndromes with multiple etiologies (that is, ones that may arise from any number of conditions), they are most commonly seen in bipolar disorder, a psychiatric illness characterized by alternating periods of mania and depression.[68][69]

Epilepsy

[edit]

Euphoria may occur during auras of seizures[70][71] typically originating in the temporal lobe, but affecting the anterior insular cortex. This euphoria is symptomatic of a rare syndrome called ecstatic seizures,[72][73] often also involving mystical experiences.[74] Euphoria (or more commonly dysphoria) may also occur in periods between epileptic seizures. This condition, interictal dysphoric disorder, is considered an atypical affective disorder.[75][76] Persons who experience feelings of depression or anxiety between or before seizures occasionally experience euphoria afterwards.[77]

Migraine

[edit]

Some persons experience euphoria in the prodrome – hours to days before the onset – of a migraine headache.[78][79][80] Similarly, a euphoric state occurs in some persons following the migraine episode.[78][80]

Multiple sclerosis

[edit]

Euphoria sometimes occurs in persons with multiple sclerosis as the illness progresses. This euphoria is part of a syndrome originally called euphoria sclerotica, which typically includes disinhibition and other symptoms of cognitive and behavioral dysfunction.[81][82]

Gender euphoria

[edit]

Gender euphoria is satisfaction or enjoyment felt by a person due to consistency between their gender identity and gendered features associated with a gender different to the sex they were assigned at birth. It is considered to be the positive counterpart of gender dysphoria.[83] Related euphorias have also been recorded in studies of alignments between sexual identity and social recognition such as support in schools for lesbian and gay people, and experiences of intersex variation and their diagnoses such as receiving a diagnosis of congenital adrenal hyperplasia which explained physical differences for example.[84]

Recent human data have demonstrated that the SEEKING brain circuitry, as predicted, is involved in the emergence of a characteristic appetitive affective state, which may be described as "enthusiastic positive excitement" or "euphoria" (Drevets et al., 2001; Volkow and Swanson, 2003) and that do not resemble any kind of sensory pleasure (Heath, 1996; Panksepp et al., 1985) ... However, in our view, cognitive processes, are only one "slice of the pie", and gamma oscillations may be more globally viewed as the overall emotional–motivational neurodynamics through which the SEEKING disposition is expressed, accompanied by a feeling of excitement/eurphoria (not 'pleasure') that is evolutionarily designed to achieve a diversity of useful outcomes

Depressed mood and anhedonia (lack of interest in pleasurable activities) in depressed individuals, and euphoria and increased involvement in goal-directed activities in patients, who experience mania, may reflect opposing abnormalities in the nucleus accumbens, medial prefrontal cortex, amygdala, or other structures. ... Although short-term administration of glucocorticoids often produces euphoria and increased energy, the impact of long-lasting increases in endogenous glucocorticoids produced during depression can involve complex adaptations such as those that occur in Cushing syndrome (Chapter 10). ... Exposure to addictive chemicals not only produces extreme euphoric states that may initially motivate drug use, but also causes equally extreme adaptations in reinforcement mechanisms and motivated behavior that eventually lead to compulsive use. Accordingly, the evolutionary design of human and animal brains that has helped to promote our survival also has made us vulnerable to addiction.

Under normal conditions, it is not surprising that sexual activity is physiologically regulated by the reward circuitry of the brain, specifically by dopaminergic pathways (see Figure 1). Moreover, the early stages of a new, romantic relationship can be a powerful and absorbing experience. Individuals in new romantic relationships report feeling euphoric and energetic. They also become emotionally dependent on, desire closeness with, and have highly focused attention on their partner (Reynaud et al. 2010; Young 2009). Human neuroimaging studies have shown that feelings experienced during the early stages of a romantic relationship are associated with neural activations in several reward-system and affect-processing regions of the brain (Young 2009; Aron et al. 2005; Bartels & Zeki 2000; Mashek, Aron & Fisher 2000).

So it makes sense that the real pleasure centers in the brain – those directly responsible for generating pleasurable sensations – turn out to lie within some of the structures previously identified as part of the reward circuit. One of these so-called hedonic hotspots lies in a subregion of the nucleus accumbens called the medial shell. A second is found within the ventral pallidum, a deep-seated structure near the base of the forebrain that receives most of its signals from the nucleus accumbens. ...
         On the other hand, intense euphoria is harder to come by than everyday pleasures. The reason may be that strong enhancement of pleasure – like the chemically induced pleasure bump we produced in lab animals – seems to require activation of the entire network at once. Defection of any single component dampens the high.
         Whether the pleasure circuit – and in particular, the ventral pallidum – works the same way in humans is unclear.

New York: Henry Holt and Company. pp. 119–120. Retrieved 16 April 2017 – via Internet archive. Something was said before about "organic states", under the general head of tendencies to reaction. Fatigue was an example. Now we could include fatigue under the term, "stirred-up state of the organism"; at least, if not precisely "stirred-up", it is uneasy. It is a deviation from the normal or neutral state. Also, it is often a conscious state, as when we speak of the "tired feeling"; not a purely cognitive state, either not simply a recognition of the fact that we are fatigued but a state of disinclination to work any longer. Though fatigue is thus so much like an emotion that it fits under our definition, it is not called an emotion, but a sensation or complex of sensations....
         Many other organic states are akin to emotion in the same way. The opposite of fatigue, the "warmed-up" condition, brought on by a certain amount of activity after rest, is a case in point. It is a deviation from the average or neutral condition, in the direction of greater readiness for activity. The warmed-up person feels ready for business, full of "ginger" or "pep" in short, full of life. The name "euphoria", which means about the same as "feeling good", is given to this condition. Drowsiness is another of these emotion-like states; but hunger and thirst are as typical examples as any.     Open access icon

Euphoria in psychiatric terms always has a pathological connotation and is often an important early sign of organic cerebral disease. It differs from elation in subtle but important ways. It has no infectious quality and no element of gaiety, for its bland contentment is based on lack of awareness and inability to experience sadness or anxiety rather than on anything positive.

The functional connectivity between brain regions mediating reward, autonomic and cognitive processing provides insight into understanding why listening to music is one of the most rewarding and pleasurable human experiences. Musical stimuli can significantly increase extracellular DA levels in the NA. NA DA and serotonin were found significantly higher in animals exposed to music. Finally, passive listening to unfamiliar although liked music showed activations in the NA. ... Music can arouse feelings of euphoria and craving, similar to tangible rewards that involve the striatal DAergic system [16]. Reward value for music can be coded by activity levels in the NA, whose functional connectivity with auditory and frontal areas increases as a function of increasing musical reward [19]. ... Listening to pleasant music induces a strong response and significant activation of the VTA-mediated interaction of the NA with the hypothalamus, insula and orbitofrontal cortex [1].
    Conclusions
    Listening to music strongly modulates activity in a network of mesolimbic structures involved in reward processing including the NA. Music, acting as a positive pleasant emotion, increases NA DAergic activity. Specifically the NA is more involved during the experience of peak emotional responses to music. Reward value of music can be predicted by increased functional connectivity of auditory cortices, amygdala and ventromedial prefrontal regions with the NA. Further research is needed to improve our understanding of the NA role in the influence of music in our lives.

Neuroimaging studies show that the reward system of the human brain is central to this experience. Specifically, the dorsal and ventral striatum release dopamine when listening to pleasurable music, and activity in these structures also codes the reward value of musical excerpts. Moreover, the striatum interacts with cortical mechanisms involved in perception and valuation of musical stimuli. ... Development of a questionnaire for music reward experiences has allowed the identification of separable factors associated with musical pleasure, described as music-seeking, emotion-evocation, mood regulation, sensorimotor, and social factors. Applying this questionnaire to a large sample uncovered approximately 5% of the population with low sensitivity to musical reward in the absence of generalized anhedonia or depression. Further study of this group revealed that there are individuals who respond normally both behaviorally and psychophysiologically to rewards other than music (e.g., monetary value) but do not experience pleasure from music despite normal music perception ability and preserved ability to identify intended emotions in musical passages.

Listening to pleasurable music is often accompanied by measurable bodily reactions such as goose bumps or shivers down the spine, commonly called "chills" or "frissons." ... Overall, our results straightforwardly revealed that pharmacological interventions bidirectionally modulated the reward responses elicited by music. In particular, we found that risperidone impaired participants' ability to experience musical pleasure, whereas levodopa enhanced it. ... Here, in contrast, studying responses to abstract rewards in human subjects, we show that manipulation of dopaminergic transmission affects both the pleasure (i.e., amount of time reporting chills and emotional arousal measured by EDA) and the motivational components of musical reward (money willing to spend). These findings suggest that dopaminergic signaling is a sine qua non condition not only for motivational responses, as has been shown with primary and secondary rewards, but also for hedonic reactions to music. This result supports recent findings showing that dopamine also mediates the perceived pleasantness attained by other types of abstract rewards (37) and challenges previous findings in animal models on primary rewards, such as food (42, 43).

(1) present evidence that enhancing or inhibiting dopamine signaling using levodopa or risperidone modulates the pleasure experienced while listening to music. ... In a final salvo to establish not only the correlational but also the causal implication of dopamine in musical pleasure, the authors have turned to directly manipulating dopaminergic signaling in the striatum, first by applying excitatory and inhibitory transcranial magnetic stimulation over their participants' left dorsolateral prefrontal cortex, a region known to modulate striatal function (5), and finally, in the current study, by administrating pharmaceutical agents able to alter dopamine synaptic availability (1), both of which influenced perceived pleasure, physiological measures of arousal, and the monetary value assigned to music in the predicted direction. ... While the question of the musical expression of emotion has a long history of investigation, including in PNAS (6), and the 1990s psychophysiological strand of research had already established that musical pleasure could activate the autonomic nervous system (7), the authors' demonstration of the implication of the reward system in musical emotions was taken as inaugural proof that these were veridical emotions whose study has full legitimacy to inform the neurobiology of our everyday cognitive, social, and affective functions (8). Incidentally, this line of work, culminating in the article by Ferreri et al. (1), has plausibly done more to attract research funding for the field of music sciences than any other in this community.
    The evidence of Ferreri et al. (1) provides the latest support for a compelling neurobiological model in which musical pleasure arises from the interaction of ancient reward/valuation systems (striatal–limbic–paralimbic) with more phylogenetically advanced perception/predictions systems (temporofrontal).

Patients in the 'classic' subgroup (approximately 20% of all migrainers) experience a characteristic aura before the onset of migraine head pain.... A much larger proportion of patients describe prodromal symptoms, which may be visceral, such as diarrhea or nausea, but are more commonly alterations in mood or behavior. Food cravings, mild euphoria (conversely, yawning), and heightened sensory perception, particularly of smell, are surprisingly common....
         The attack often terminates with sleep.... Many patients report a 'hangover' on waking after a migraine, but others report complete freedom from symptoms and a sense of euphoria.     [emphasis added]
