    ### 5 simple tips on how to organize your workspace at home

    1. **Proper lighting.** Place a cold light lamp 4000–4500 K on the left (on the right — for left-handed people) to avoid shadows.

    2. **Ergonomic chair.** A backrest with lumbar support and height adjustment reduces spinal fatigue by 30% (WHO data, 2024).

    3. **"Clean desk" zone.** Keep only what you need today on the desk; store everything else in a drawer.

    4. **Cable management.** Clips and flexible sleeves eliminate wire chaos and free up ≈ 20% of useful space.

    5. **Micro-breaks.** The Pomodoro timer (25/5) increases concentration by 15% according to *Harvard Business Review*, 2025.

    > Even one implemented tip will noticeably increase productivity and preserve health.
