Detailed Answer
To avoid speed decay in 2+ hour sessions: 1) Take a 1-minute micro-break every 20 minutes – shake hands, stretch fingers. 2) Stay hydrated – dehydration slows nerve conduction. 3) Use an ergonomic keyboard and keep wrists straight. 4) Rotate between different tasks (typing, reading, mouse work) to prevent overuse. 5) Set a comfortable pace – don't sprint at max speed for hours. 6) Use software like Workrave to enforce breaks. 7) Monitor fatigue signs (increasing errors, slower reaction). 8) Do hand warm-ups before the session. 9) Adjust chair and monitor height periodically. With good habits, you can maintain 90% of your peak WPM for 4+ hours.
