Stand, roll your shoulders, and perform ten slow squats or a gentle stair climb. Add a doorway chest stretch and ten calf raises. This minute lifts circulation, brightens alertness, and counters prolonged sitting. If you can, open a window or step onto a balcony for fresh air. Keep it consistent and time-bounded. The predictability helps your brain trust the break, releasing tension without dissolving the focus you carefully established minutes earlier.
Every twenty minutes, gaze at something twenty feet away for twenty seconds to relax eye muscles and reduce strain. If daylight is available, catch a minute outside or near a window to cue healthy circadian signals. Soft peripheral viewing also calms the nervous system. Pair this with a sip of water. Your mind often returns refreshed, with stubborn sentences resolving and problem steps becoming obvious, as if your attention learned to breathe again.
