Reaction Time and Fatigue
Why your fifth ranked match is slower than your first.
TL;DR — Reaction time drifts 20–50 ms slower after 25–40 minutes of focused play due to attention fatigue, not muscle fatigue. A 5-minute eyes-closed break fully restores baseline in most people.
The phrase "tilted" maps almost perfectly onto attention fatigue. The cure is mechanical: stand up, look away, breathe for two minutes. Five minutes restores baseline for almost everyone.
How attention fatigue differs from physical fatigue
Muscular fatigue takes hours of effort. Attention fatigue takes 25–40 minutes of sustained focus. The two systems are independent — a marathon runner can fatigue attention in 30 minutes the same as anyone else.
The fatigue curve in a single session
| Minutes of focused play | Reaction drift from baseline |
|---|---|
| 0–25 | 0 ms |
| 25–40 | +10 to +25 ms |
| 40–60 | +25 to +50 ms |
| 60–90 | +50 to +90 ms |
| 90+ | +90 ms or attention lapses |
Why short breaks work so well
Attention is gated by neurotransmitter availability in the prefrontal cortex. A 3–5 minute eyes-closed pause restores those reserves substantially. A 10-minute walk restores them fully. Scrolling on a phone does not — the same attention system stays loaded.
Building anti-fatigue into a session
- 25 minutes on, 5 minutes off — known as the Pomodoro pattern.
- Eyes closed or middle-distance gaze during the break, not screens.
- One stretch and one drink of water per cycle.
- After 3 cycles, take 20 minutes off completely.
Frequently Asked Questions
Is reaction fatigue different from being tilted?
They overlap completely in the short term. Tilt is the emotional label for attention fatigue under competitive pressure.
Can I train to resist fatigue?
Yes, but slowly. Endurance gains take 6–8 weeks of consistent practice.
Does music during play help?
Variable. Familiar instrumental music delays fatigue; lyrical or new music tends to accelerate it.
