Health
General practice for playing a lot of Tekken, and published findings on competing under stress. Nothing here is read from your match history, and none of it is medical advice. Your own numbers on sessions and tilt are on the Sessions & tilt page.
- Micro-breaks: get out of the chair between sets. Your session gap (45m) is the boundary the analytics use, but a minute between long sets is enough to matter.
- Wrists and hands: warm up before you play, not after it hurts. Wrist circles, finger spreads, forearm stretches. Stop on anything that actually hurts — pain that persists is a doctor's problem, not something to grind through.
- Water within reach. Sleep is worth more than one more set: ranked at 3am rarely goes the way the replay in your head did.
- Whether to stop for the night is a question your own record can answer. The Sessions & tilt page compares what happens when you keep queueing after a losing run against what happens when you step away.
Each finding below links its source. The 'assumption' lines are guesswork about how it might matter in competitive play. They are not established research, and none of this is medical advice.
In a study using subliminal emotional priming, anger primes slowed participants' reaction times on decision-making tasks compared to relaxed primes, and this slowing was linked to increases in systolic blood pressure.
assumption · If anger measurably slows reaction time, a tilted player is plausibly later on exactly the skills that live in tight windows — block punishes, throw breaks, whiff-punish launchers. The frames you lose to tilt are the same frames you trained.
Anger in brain and body: the neural and physiological perturbation of decision-making by emotion ↗
Research on 'tilt' in competitive gaming found that taking breaks improved executive functioning among esports players, while seeking distraction was identified as a protective emotion-regulation strategy against tilt.
assumption · This is the research-side echo of a comparison the site makes on your own record: stepping away after losses may restore the executive function that matchup recall and mid-set adaptation depend on, while queueing on may simply spend it. The continue-versus-break split on Sessions & tilt is a personal test of this assumption.
An eye-tracking study found that angry participants looked more, and earlier, toward heuristic (shortcut) cues while making decisions, indicating a shift toward more intuitive and less analytical processing under anger.
assumption · A shift toward heuristic (gut) processing under anger reads, in Tekken terms, as panic habits: mashing after blocked strings, raw power crush on wake-up, ducking on feel rather than on read. Knowledge checks are analytical by nature — this finding suggests anger switches off the very mode that passes them.
Effects of anger and sadness on attentional patterns in decision making: an eye-tracking study ↗
In a study of middle-to-older-aged community-dwelling adults, the more dehydrated participants were, the worse they performed on a sustained attention task, though other cognitive measures such as working memory were not significantly affected.
assumption · Sustained attention is the long-set skill: an under-hydrated player may hold even for two games and fade in the third — dropped combos, late reactions to seen lows. The assumption is that late-session sloppiness is sometimes hydration, not skill.

Reported by Penn State University on a study published in the American Journal of Human Biology.
The U.S. National Academies (Institute of Medicine) set Adequate Intake reference values for total water — from all beverages and food combined — at 2.7 liters (91 ounces) per day for women and 3.7 liters (125 ounces) per day for men in temperate climates, with higher needs for very physically active people or those in hot climates.
assumption · A reference intake is a baseline, not a target to chase mid-set; the assumption is that sessions run far below it are the ones where the attention fade above becomes likely.
Harvard Health notes that brain health depends on adequate nutrition, and that dietary patterns such as the Mediterranean diet are associated with a lower likelihood of mild cognitive impairment and slower progression to dementia in those who have it.
assumption · Long-horizon assumption: a dietary pattern associated with slower cognitive decline protects, over years, the faculties ranked Tekken leans on hardest — matchup memory and processing speed. This is about a career of play, not tonight's session.
A systematic review and meta-analysis found that both acute (single-session) and chronic (repeated, long-term) exercise can improve executive function — including working memory, inhibitory control, and cognitive flexibility — in children and adolescents.
assumption · If a single exercise session can sharpen executive function, a pre-session workout plausibly improves inhibitory control — in fighting-game terms, the discipline of NOT pressing when minus. (The cited study population is young; the assumption extends it to adults.)
Effect sizes varied by domain: moderate for working memory, small for inhibitory control and cognitive flexibility.
The U.S. 2018 Physical Activity Guidelines Advisory Committee found strong evidence that high amounts of sedentary behavior (e.g., prolonged sitting) increase the risk of all-cause and cardiovascular disease mortality, as well as incident cardiovascular disease and type 2 diabetes.
assumption · The risk pattern named by this evidence is exactly the marathon seated session. The assumption: breaking long sessions up serves long-term health and — via the break findings under Tilt — possibly same-day win rate too.
A U.S. government advisory-committee scientific report, hosted on NIH PMC.
A one-year Mayo Clinic follow-up study of frequent computer users (averaging about 6 hours of daily use) found that computer/keyboard use does not appear to pose a significant occupational hazard for developing carpal tunnel syndrome, with rates of confirmed carpal tunnel syndrome similar to the general population.
assumption · Reassuring assumption for controller hours as such: time alone doesn't appear to be the wrist threat it's often assumed to be. The heavy-mouse caveat maps loosely onto intense repetitive grip — so persistent wrist pain during play points at grip, posture, or something that deserves a professional's eyes, not simply the hour count.
Computer Use and Carpal Tunnel Syndrome: A 1-Year Follow-up Study ↗
Some association was noted with heavy mouse use (>20 hrs/week); established RSI risk factors such as forceful grip and vibration are more clearly linked to carpal tunnel syndrome than computer use itself.
A 2023 controlled study testing scheduled screen breaks (every 5, 10, 20, or 40 minutes) during a 40-minute digital reading task found no significant effect of the break schedule on reported eye-strain symptoms, reading speed, or accuracy, and concluded the results do not support scheduled 20-second breaks as a therapeutic intervention for digital eye strain.
assumption · The popular 20-20-20 rule may not, by itself, fix eye strain — the evidence is genuinely mixed. The assumption: comfort in long sessions depends more on the whole setup (viewing distance, lighting, sleep) than on any single timed micro-break ritual.
20-20-20 Rule: Are These Numbers Justified? ↗
The authors caution this is not evidence that breaks cannot help — only that scheduled 20-second breaks were not a proven intervention in this task.
In a study of Korean adolescents, both male and female participants reporting excessive high-caffeine drink consumption exhibited higher anxiety levels, and this association was strongest among those sleeping six or fewer hours per night.
assumption · Energy-drink-fueled late-night queues stack two performance risks this research names: anxiety (jitter where clean execution wants calm hands — KBD and just-frame timing are the obvious casualties) and short sleep, which amplified the association. The assumption is that the third energy drink is trading execution for alertness.

Acute cannabis use is associated with slower reaction time, with a study of occasional users finding measurable reaction-time decrements after inhalation, whereas daily users showed no significant change, consistent with tolerance.
assumption · Slower reaction time in occasional users maps directly onto later throw breaks and missed punish windows. The assumption: ranked play shortly after use costs frames precisely where frames decide rounds — and the tolerance finding cuts both ways, describing adaptation, not safety.
Nicotine withdrawal is described by NIDA as producing cognitive and attention deficits, including problems with attention or memory, alongside irritability, anxiety, and sleep disturbances.
assumption · For a player who smokes and is cutting back, withdrawal's documented attention and memory deficits plausibly show up as mid-set matchup amnesia and irritability that reads like tilt but isn't match-caused. The assumption: expect a temporary floor drop during withdrawal and judge your results accordingly — the finding describes withdrawal, it does not argue for or against nicotine.
During acute stress, sympathetic nervous system activation increases heart rate, alters breathing into rapid shallow patterns, and can exacerbate musculoskeletal tension.
assumption · Stress has a physical signature you can check between rounds: heart rate, shallow breathing, tense shoulders and forearms. The assumption: your body announces tilt earlier than your results do — a match history can only show a losing streak after it happened; your grip tension shows it now.
A moderate, statistically significant association has been found between self-reported bruxism (teeth grinding/jaw clenching) and self-reported stress in a student population.
assumption · Jaw clenching mid-set is, by this association, a candidate stress tell. The assumption: catching yourself clenching during a losing run is a cheap, immediate tilt check — no data required.
Correlational/self-report study (n=328 dental students); association, not causation.
In a controlled study, slow-paced breathing altered the balance of cardiac autonomic activity, increasing the LF/HF heart rate variability ratio compared to resting baseline, though average heart rate itself did not change significantly.
assumption · Slow breathing measurably moves autonomic balance, with the researchers' own hedges intact. The cautious assumption: a slow breath between rounds may nudge arousal in a useful direction — a small lever, not a reset button.

Authors interpret this as shifting sympathovagal balance, not simply increased parasympathetic dominance.
An 8-week body-scan mindfulness intervention was associated with measurable improvement in interoceptive accuracy (heartbeat perception), with scores rising from 0.60 to 0.71 on a standard interoception task between the start and end of the study.
assumption · Interoception — reading your own body — is trainable, per this study. The assumption: a player who practices noticing internal signals detects their own tilt signs sooner, which complements the statistical tilt measures this site computes from your match history.
Improvement of Interoceptive Processes after an 8-Week Body Scan Intervention ↗
Interoceptive accuracy = the ability to detect internal bodily signals like heartbeat; a within-group pre/post improvement in a body-scan practice group.
