Stop Breath-Holding at Work: Techniques to Reduce Dizziness and Nausea

Unconscious breath-holding during concentration ("email apnea" or "screen apnea") causes CO₂ buildup and O₂ drop, leading to dizziness, nausea, and cognitive fog.

Evidence-Based Strategies

1. Breath awareness: Periodic check-ins; set hourly timer. Notice pauses/shallow breathing.
2. Diaphragmatic breathing: 5–10 min daily: inhale 4s (belly rises), hold 2s, exhale 6s. Activates vagus nerve, lowers stress.
3. Visual cues: Sticky note "BREATHE" on monitor; phone vibration reminders.
4. Micro-breaks: Every 60 min: stand, stretch, walk 2 min. Resets breathing, improves circulation.
5. Identify triggers: High-stakes emails, debugging, meetings. Pre-empt with 3 slow breaths before starting.
6. Ergonomics: Monitor at eye level, lumbar support, relaxed shoulders → reduces physical tension that restricts breathing.
7. Professional help: Persistent breath-holding → respiratory therapist, CBT for anxiety, medical eval for sleep apnea/asthma.

Consistent practice rewires the habit. Benefits: better focus, less fatigue, lower stress.
