Most Pleasurable Things a Human Can Experience

Scientific concepts, discoveries, and nature/biological phenomena

How pleasure works in the brain (neurochemistry and reward pathways)

• Pleasure is subjective and “slippery” to define, so the neuroscience of pleasure remains debated.
• Dopamine
  • A neurotransmitter in the brain’s reward system.
  • Involved in sleep, pain processing, learning, and other functions.
  • Low dopamine is (in general terms) associated with depression and reduced motivation/concentration.
• Dopamine is necessary but not sufficient
  • Example: levodopa increases dopamine availability (used for Parkinson’s) but does not directly increase pleasure/happiness—it primarily improves Parkinson’s symptoms.
  • Dopamine is compared to “petrol for a car”: essential for function, not a direct guarantee of more pleasure.
• Other key pleasure-linked chemicals
  • Endorphins: endogenous opioid neuropeptides (in the central nervous system + pituitary). Also produced artificially by opiate-class drugs. Both can stimulate reward activity and relate to euphoria and reduced pain.
  • Oxytocin (“love hormone”): released during positive social interactions, sexual activity, and physical intimacy.
  • Serotonin: SSRIs affect serotonin absorption. Serotonin is described as more about enabling/smoothing the experience of natural happiness/pleasure rather than directly causing it.
  • Glutamate: activates the reward pathway.
  • GABA: inhibits neural areas involved in anxiety/stress, including the amygdala.
• Brain structures implicated in pleasure
  • Orbitofrontal cortex (behind the eyeballs)
  • Nucleus accumbens
  • Ventral pallidum
  • Presented as a network working together—no single “golden ticket” chemical.

Types/categories of pleasure

• Hedonic pleasure (immediate, sensory-based)
  • Often described in stages: wanting → liking → learning
  • Example flow: anticipation → taste/experience → satisfaction and closure
• Eudaimonic pleasure (meaning-based)
  • Comes from community engagement, positive change, and feeling life is meaningful
  • May feel less pleasurable “in the moment,” but can be rewarding in hindsight

Sex and orgasm as a major pleasure example (sexual response biology)

• Orgasm
  • Happens after genital stimulation (or other erogenous zones).
  • Described as the third stage in the sexual response cycle: desire (libido) → excitement/arousal → orgasm
  • Includes muscle contractions, increased heart rate and breathing, and release of dopamine and oxytocin
• Six types of orgasms (via Healthline, as cited)
  • Clitoral
  • Vaginal (linked to stimulation of the G-spot, described as being along the vaginal wall)
  • Anal (described via stimulation of the prostate, including contractions around the anal sphincter)
  • Blended (simultaneous clitoris + vagina; may involve full-body tremors)
  • Erogenous (non-genital zones such as ears, nipples, neck, elbows, knees)
  • Convulsing (pelvic floor convulsions; potentially linked to edging)
• Injection-based “pleasure” procedures mentioned (as described in subtitles, including names)
  • O-Shot / Orgasm Shot: platelet-rich plasma (PRP) injected into the clitoris and within the vagina
  • G-Shot: hyaluronic acid injected into the G-spot
  • Presented as treatments intended to increase sensation/arousal

Pleasure–pain relationship (“pleasant pain” and contrast effects)

• Paul Bloom (2021)
  • Argues that people sometimes use pain to increase contrast, so relief after pain can outweigh initial discomfort—turning it into pleasure.
• University of Melbourne + University of Queensland findings (as described)
  • If subjects experience discomfort/pain before a pleasurable stimulus, reported pleasure increases
  • Example: cold exposure → chocolate tastes better
• Siri Leknes and colleagues (clinical trial)
  • Context can “flip” pain into relief
  • 16 healthy volunteers experienced moderate pain in two contexts:
    • Control: worst possible outcome is moderate pain → hedonic response negative
    • Relative relief: worst possible outcome is intense pain → moderate pain feels like relief → hedonic response positive
  • Framed as a “hedonic flip,” with increased reward-related activity in:
    • medial orbitofrontal cortex
    • ventromedial prefrontal cortex
• Pain can be pleasurable for some people (examples given)
  • Spicy foods (“makes them cry”)
  • Extreme exercise
  • Tattoos/piercings
  • Sadomasochism

“Runner’s high” and exercise-related opioid/cannabinoid-like mechanisms

• Vigorous exercise releases pain-related signals, described via:
  • Lactic acid activating pain receptors in muscles
  • Endorphins produced via the hippocampus, binding opioid receptors to reduce pain
• Neural overlap
  • Endorphins are described as stimulating brain regions also activated by sex and listening to music
• Anandamide
  • Described as a second “painkiller/bliss chemical”
  • Binds cannabinoid receptors to reduce pain signals and induce “warm/fuzzy” pleasure (compared to effects associated with marijuana)
• Benign masochism
  • Defined as enjoying pain that is not expected to cause lasting damage
  • Examples: spicy foods, consensual BDSM/sadomasochism

Spicy foods and why humans may perceive them differently

• The text claims: animals can’t distinguish burning from actual harm (as stated), while humans can treat spice burn as pleasure/indulgence
• Used to support the “benign masochism” framing

Music/food/art as pleasure triggers (neurochemical associations mentioned)

• Food
  • Cheese (as noted in subtitles) linked to dopamine
  • Chocolate linked to serotonin
• Music
  • Described as lighting up brain areas connected to pleasure associated with sex and food

Stress relief and everyday “pleasure” examples from popular sources

Not presented as controlled neuroscience experiments; compiled as examples.

• Examples include:
  • Good meals, sunsets, relaxing physical comfort (fresh sheets, warm baths)
  • Stretching, cuddling a pet (dopamine via “fluffy face”)
  • Finishing workouts, beach/sand, sleeping in
  • Non-orgasmic pleasures (e.g., laughing, hugs, warm baths after cold, unexpected financial help, skin-on-skin affection, mutual love recognition, major accomplishments)
  • Art and immersion (movies, books)
  • Massage, coffee + croissant, dog companionship, hiking
  • Observing plant growth (“miracle of growth”)
  • Reddit examples: family moments after hospital, lucid dreaming, cooking enjoyment, post-camping shower/bed, school-cancelled relief, hearing “I love you.”
